To understand the iSM functions and to use the iSM efficiently, first read through this chapter, then proceed to Chapter 2. 11..11 D Diisskk A Arrrraayy The outline of the disk array which is the object of the iSM management is explained below. (1) 4000 series The 4000 series, high-end disk array, realizes high scalability (up to 10 extended cabinets can be connected to a basic cabinet) and high availability (all components have redundancy) and displays stable performance. Furthermore, it provides the function to replicate logical disks (DynamicDataReplication and RemoteDataReplication) in and between disk arrays, which enables backup and batch processing to be performed in parallel with the main function. (2) 3000 series The 3000 series, mid-range disk array that can handle key business, realizes high scalability (up to 2 extended cabinets can be connected to a basic cabinet) and high availability (all components have redundancy) and displays stable performance. Furthermore, it supports functions equivalent to all of the solutions (DynamicDataReplication, RemoteDataReplication, etc.) provided by the 4000 series, the high-end disk array, thereby efficiently performing business. (3) 2800 series The 2800 series, mid-range disk array, realizes high scalability (up to 16 disk enclosures can be added) and high availability (main components have redundancy). In addition, it provides a function to replicate logical disks (DynamicDataReplication) in the disk array, which enables effective backup and batch processing. Furthermore, the 2800 series can supports an additional parity disk for the high reliability RAID (RAID6) to secure the redundancy against an error in one physical disk. I-2 Chapter 1 Storage Overview (4) 2000 series - S2100/S2200/S2300 S2100/S2200/S2300, mid-range disk array, realizes high scalability (up to 14 disk enclosures can be extended) and high availability (main components have redundancy). Furthermore, it provides a function to replicate logical disks (DynamicDataReplication) in the disk array, which enables effective backup and batch processing. - S2400 S2400, mid-range disk array, realizes high scalability (up to 8 disk enclosures can be added) and high availability (main components have redundancy). In addition, it provides a function to replicate logical disks (DynamicDataReplication, RemoteDataReplication) in and between disk arrays, which enables effective backup and batch processing. Furthermore, this version can support an additional parity disk for the high reliability RAID (RAID6) to secure the redundancy against an error in one physical disk. (5) 1000 series - S1100/S1200/S1300 S1100/S1200/S1300, a low-end model disk array, realizes the little space consuming (one controller and maximum of 15 PDs may be loaded per 3U) and high availability (main components have redundancy). - S1400 S1400, a low-end model disk array, realizes space saving (one controller and a maximum of 15 PDs may be installed per 3U) and high availability (main components have redundancy). In addition, it provides a function to replicate logical disks (DynamicDataReplication) in the disk array, which enables effective backup and batch processing. Furthermore, this version can support an additional parity disk for the high reliability RAID (RAID6) to secure the redundancy against an error in one physical disk. (6) 100 series - S100 The 100 series, entry model disk array designed for Windows/Linux, realizes space saving (one controller and a maximum of 15 PDs may be installed per 3U) and high availability (main components have redundancy). - S400 S400, entry model disk array designed for Windows/Linux, realizes space saving (one controller and a maximum of 15 PDs may be installed per 3U) and high availability (main components have redundancy). Furthermore, this version can support an additional parity disk for the high reliability RAID (RAID6) to secure the redundancy against an error in one physical disk. I-3 Chapter 1 Storage Overview 11..22 D Diisskk A Arrrraayy C Co on nffiig gu urraattiio on n (1) Components The disk array is composed of Disk Array Controller (DAC), which carries the component of control systems, such as host director, disk director and cache, and Disk Enclosure (DE) that carries two or more Physical Disks controlled by DAC. Array Group 2 Array Group 0 Array Group 1 (up to 10 cabinets) Figure 1-1 Disk Array Composition (4000 Series) I-4 Chapter 1 Storage Overview Array Group 2 Array Group 0 Array Group 1 (up to 2 cabinets) Figure 1-2 Disk Array Composition (3000 Series) Figure 1-3 Disk Array Composition (2000/2800 Series) Disk Enclosure (DE) Disk Array Controller (DAC) Physical Disk (PD) Figure 1-4 Disk Array Composition (100/1000 Series) I-5 Chapter 1 Storage OverviewIn the 3000/4000 series disk array, the cabinet composed of Disk Array Controller and two or more disk enclosures is called as “Basic Cabinet (BC)” and the cabinet that is composed of multiple disk enclosures to be connected to basic cabinet is called as “Extended Cabinet (EC)”. The 3000/4000 series disk array can mount 10 or 15 Physical Disks (PDs) per disk enclosure, and 4 disk enclosures are managed as 1 group (array group). Individual PD has identification number per PD management group (PD group) that includes the above 4 array groups. Thus the combination of PD group number and PD position number enables identifying of the physical mounting place of the PDs. In the same way, unique identification number is assigned to other components in disk enclosure (shown below), per controller unit, and this identification number enables components in the same disk enclosure to be specified. But assignment of identification number depends on number of component in disk enclosure. The 2800 series disk array is composed of Disk Array Controller (DAC) and one or more disk enclosures. (There has no concept of basic cabinet and extended cabinet as in the 4000 series). It can mount 15 physical disks (PDs) per disk enclosure. Only one PD management group (PD group) is defined in it (i.e., all physical disks belong to one PD group). There is no concept of array group. The 2000 series disk array is composed of Disk Array Controller (DAC) and one or more disk enclosures. (There has no concept of basic cabinet and extended cabinet as in the 4000 series). It can mount 10 or 15 Physical Disks (PDs) per disk enclosure. PD management group (PD group) is defined depending on the connection relation to disk array controller. (PDs connected to the same group are defined as one PD group) There is no concept of array group. In the 100/1000 series disk array, Disk Array Controller (DAC) and DE which are in different cabinets in the 2000 series are put in the same cabinet. Controller (DAC). 15 Physical Disks (PDs) can be carried in Disk Array Because there is not the concept of array group, the Physical Disks connected to the same group are managed as one group (PD group).

Data on the logical disks is stored into the areas of physical disk associated with the partitions on the virtual medium in which the logical disks are composed. The virtual medium is called a pool or RANK, and it supports different logical disk configurations depending on the disk array. • Pool Disk arrays with pool *The disk arrays with pool are the following: S400/S1400/S2400/S2800 In the disk array indicated above, multiple physical disks put together to make up a virtual medium for RAID is called a pool. The logical disks usually belong to one pool, and the required amount of space is assigned from the pool. There are two types of pool available as described below. They function in different manners. Basic pool The basic pool is a virtual medium, which manages the space on the pool using a continuous address space. As you handle logical disks on RANK, assign the continuous space on the pool to the logical disks. In addition, like a multi-RANK configuration, the basic pool supports a striping configuration for distributing and storing data into multiple RAID configurations. For the practical configurations of physical disks that bind a basic pool, refer to C.3 “List of Pool-Configurable RAID Types”. Note that the basic pool does not allow using any additional features such as pool capacity expansion or logical disk capacity expansion. I-18 Chapter 1 Storage Overview Dynamic pool The dynamic pool is a virtual medium, which manages the space on the pool using a virtual storage space. Like block management in a file system, the dynamic pool manages used space and unused space. When making up logical disks, separate unused space from the pool according to the required capacity, then assign the physical disk space corresponding to the logical disk space. The dynamic pool moderates the limit on the number of constituent physical disks and enables flexible configurations. In addition, the dynamic pool allows to use additional features such as pool capacity expansion and logical disk capacity expansion. For details on the dynamic pool, refer to 2.1.2 “Dynamic Pool”.

PDnn Logical Configuration of Disk Arrays (Dynamic Pool) S400/S1400/S2400/S2800 disk array supports the dynamic pool function. The dynamic pool function puts a set of physical disks on the disk array together to make up a virtual storage pool. That is, it picks up the amount of storage required for the transaction from space unused in the pool and bind logical disks. If the storage capacity becomes short, you can add physical disks one by one as required and putting them into the pool to expand the unused space of the pool. The additional unused space of the pool can be used to bind a new logical disk or expand the existing logical disk capacity, keeping the current data. In addition, you can put back logical disks no longer needed to the pool to extend the unused space of the pool. Therefore, the dynamic pool function helps to manage the capacity of the storage efficiently and make a large reduction in the cost on additional storage space. It also helps to flexibly support any configuration changes or expansion of the storage to be done for addition of new transactions or modification to existing transactions. I-24 Chapter 2 Overview of Disk Array Configuration Setting Server Add physical disks one by one as required to the pool to expand the available space. Logical Disk Create a new logical disk. Expand the existing logical disk capacity, keeping the current data. Physical Disk Pool Put back a logical disk no longer needed to the pool. Disk Array Figure 2-4 Overview of the Dynamic Pool Function The dynamic pool function provides the following advantages: • Reduction in the cost of storage expansion When some additional storage space is required due to an addition of new transactions and so forth, you can add physical disks one by one as required to bind a new logical disk or expand the logical disk capacity at that time. This means that you can add physical disks just enough for the required capacity only with the least additional cost. • Better flexibility of storage configuration If the amount of data to be handled increases and the storage capacity becomes short, you can expand the logical disk space, keeping the existing data in the logical disks. In addition, returning logical disks no longer needed to the pool secures the unused space of the pool which can be used for another purpose. With these features, you can flexibly support any configuration changes of storage to be made for modification to existing transactions or operation of existing transactions. I-25 Chapter 2 Overview of Disk Array Configuration Setting (1) You can bind a dynamic pool: You can bind a virtual storage space, or a dynamic pool, by selecting a set of unused physical disks on the disk array. The RAID type usable and the number of physical disks required for a dynamic pool are fixed. Select either of the following two types of RAID6 configuration according to the number of physical disks required. The two types of configuration have different capacity efficiencies: RAID6 (4+PQ): 6 or more physical disks required (capacity efficiency: 67% approx.) RAID6 (8+PQ): 10 or more physical disks required (capacity efficiency: 80%) For details on how to bind a dynamic pool, refer to 7.1.1 “Binding a Pool” in Part IV “Operations”. y Dynamic pool RAID Type RAID6 (4+PQ) Disk Array Number of Physical Disks S400/S1400/ 6 to 60 S2400/S2800 (120 or 240)*1 RAID6 (8+PQ) 10 to 60 (120 or 240)*1 *1: The maximum number of physical disks is 60 when pools are in use. To use 61 or more disks, you need to add physical disks by extending dynamic pools. (2) You can expand the dynamic pool capacity: You can expand the capacity of the dynamic pool by selecting unused physical disks on the disk array and putting them into the dynamic pool. The capacity actually added is the capacity of the additional physical disk(s) multiplexed by the pool capacity efficiency. disks one by one. You can add physical Naturally, you can add multiple physical disks at one time. Usually, expanding the dynamic pool rebuilds data on the additional physical disk(s) to keep the redundancy of RAID. Rebuilding data puts some load to the physical disks of the dynamic pool and influences access to the existing logical disks which belong to the pool. The additional space becomes available after the rebuild process finishes. However, when the number of physical disks simultaneously added to the pool is a specified number or more, the dynamic pool is expanded and made available without the rebuild process. The additional space is usable immediately after the physical disks are added to the pool. The RAID configuration cannot be changed from RAID6 (4+PQ) to RAID6 (8+PQ) or vise versa. You need to add physical disks to the pool, keeping the RAID configuration. I-26 Chapter 2 Overview of Disk Array Configuration Setting For details on how to expand a dynamic pool, refer to 7.1.2 “Expanding Capacity of a Pool” in Part IV “Operations”. Additional Physical Disks Configuration 1 to 5 RAID6 (4+PQ) 1 to 9 RAID6 (8+PQ) 6 or more RAID6 (4+PQ) 10 or more RAID6 (8+PQ) Rebuild after Expansion of Pool The pool is rebound. Rebinding the pool influences access to the existing logical disks which belong to the pool. The additional space to the pool becomes available after the rebind process finishes. The pool is not rebound. The expansion of the pool puts no influence on any existing logical disks which belongs to it. The additional space to the pool becomes available immediately after it is added. (3) You can bind the logical disks: You can pick up the amount of storage required from the unused space in the dynamic pool and bind logical disks required for it. For details on how to bind logical disks, refer to 7.2.1 “Binding Logical Disks” in Part IV, “Operations”. (4) You can expand the logical disk capacity: You can pick up the amount of storage required from the unused space in the dynamic pool and increase the existing logical disk capacity. While data stored in the logical disks is secured, some space usable for additional logical disks is added after the existing logical disks. The way of having the host identify the additional space depends on the platform. For details on how to expand the logical disk capacity, refer to 7.2.2 “Expanding Capacity of Logical Disks” in Part IV “Operations”. Some platforms do not support expansion of logical disk capacity. For details about it, ask the maintenance personnel. In addition, in case of an error or failure, it is recommended to make a backup of data stored in the existing logical disks before expanding the logical disk capacity. I-27 Chapter 2 Overview of Disk Array Configuration Setting 22..11..33 R RA AN NK K The logical disks usually belong to one RANK, and a continuous space on one RANK is assigned to them.

Figure 2-6 Physical Disks and Logical Disks I-29 Chapter 2 Overview of Disk Array Configuration Setting 22..33 S Sp paarree When binding pools or RANKs other than RAID0, data are still in the disks even when a single physical disk (two physical disks for RAID6) fail(s). However, if one more physical disk fails, data may be in danger of being lost. To cope with this situation, the reliability of the disk array can be enhanced further by switching to a reserve (i.e. Spare) disk which is set beforehand, at the point when a physical disk fails. Spares can be set for physical disks which are not used in pool or RANK binding, thus making it possible to recover data to a Spare in the same PD group when a physical disk fails. When recovery to Spares is started, the pool or RANK is rebuilt and the Spares become physical disks which comprise the pool or RANK. The failed physical disk can be replaced without stopping the access to the disk array. Considering the physical layout, it is normally desirable to set one spare disk per DE for the physical disk in the rightmost slot in the DE. 22..44 N Niicckkn naam mee Nicknames refer to any names that can be set for the disk array, the logical disk, the port, and the pool with regard to iSM’s management target. Since the names thus set are stored in the disk array, they are held regardless of whether iSM or a disk array is restarted or not. (1) Disk Array Name Refers to any ID name for iSM’s management target disk array. When the disk array is specified with iSM, the disk array name is used. (2) LD Name Refers to any ID name for a logical disk in iSM’s management target disk array. When the logical disk is specified with iSM, the LD name is used. (3) Port Name Refers to any ID name for a port in iSM’s management target disk array. When the port is specified with iSM, the port name is used. (4) Pool Name Refers to any ID name for a pool in the iSM’s management target disk array. When the pool is specified with iSM, the pool name is used. I-30 Chapter 2 Overview of Disk Array Configuration Setting Before operating the disk array, users can perform efficient management of the disk array by setting the ID information with the nickname. I-31 Chapter 3 Overview of AccessControl Chapter 3 Overview of AccessControl This section describes functions available when program product “AccessControl” is purchased. The AccessControl is optional software. The AccessControl provides functions to set and unset information on accessibility from the business server to logical disks. Using these functions enables users to easily and flexibly change configuration of logical disks and perform accessibility setting. Disk Array Accessible Area In Use from Business Server LD Set LD Set Add/Delete of logical disks is possible. Inaccessible Area In Non-use from Business Server AccessControl function protects LDs from business server [Preserve Group] Figure 3-1 Overview of Access Control y [Inaccessible area] Logical disk groups hidden from the business server by using the AccessControl function exist in this area. This area is called Preserve Group. [Preserve Group] Logical disks hidden from the business server and inaccessible exist in this area. Contents of the logical disks are retained and existing logical disks include logical disks with no special purpose settings, logical disks set in pairs for replication (MV, RV), volume for snapshots (BV), and link-volume (LV). y [Accessible area] Logical disk groups accessible from the business server by using the AccessControl function exist in this area. Contents of the logical disks depend on the business server, and existing logical disks include ordinary logical disks with no special purpose settings, replication volume (MV, RV), volume for snapshots (BV), and link-volume (LV). In addition, each logical disk is assigned to an LD Set. I-32 Chapter 3 Overview of AccessControl 33..11 L LD DS Seett The concept of “LD Set” is introduced to Access Control. The concept of LD Set enables to assign logical disks collectively to ports of multiple disk arrays and WWNs. When one single business server has multiple access paths and if its I/O paths are duplicated or it is clustered, define multiple access paths together by using an LD Set. For ports and WWNs defined as paths of an identical LD Set, Access Control can be collectively set. That is, when you add or remove an LD Set after setting up Access Control, you can collectively handle ports and WWNs with an LD Set specified. When a disk array with the program product AccessControl(WWN) applied is in use, only WWNs can be defined as paths of LD Sets.

Then, bind the logical disks to the pool to bind the logical disks. In addition, bind a control volume individually. A control volume is a volume for control over snapshot operation. (For the details of control volumes, refer to "Snapshot User’s Manual (Function Guide)" (IS030).) After adding physical disks, take the steps stated above to the added physical disks to bind the logical disks. Adding physical disks puts no influence on any existing logical disks, which belongs to the pool and already in use. Adding and binding logical disks to the pool also puts no influence on any existing logical disks. Pools are classified into two types; the dynamic pool allows expanding the capacity of the pool and the logical disks, and the basic pool does not allow expanding the capacity of the pool and the logical disks. The logical disk configurations selectable by the pool are as follows: Logical disk configuration: Dynamic pool RAID6 (4+PQ)/(8+PQ) Basic pool RAID1 (1+1) Basic pool RAID5 (4+P) Basic pool RAID10 (1+1) × 2/(1+1) × 4/(1+1) x 8 Basic pool RAID50 (4+P) × 2/(4+P) × 4 Bind logical disks in accordance with the following procedure.

For configuration setting in S400/S1400/S2400/S2800, refer to Chapter 7. 88..11 B Biin nd diin ng g aa R RA AN NK K The RANK is bound by specifying the physical disks and the RAID type for binding RAID from the physical disks installed on the disk array. Then, for the RANK thus bound, logical disks can be bound by binding logical disks. When extending physical disks, logical disks can be bound for the extended physical disks in accordance with the same procedure, thus not affecting the logical disks on other RANKs already in use. Even when new logical disks are additionally bound for the same RANK, they do not affect the already bound logical disks. Regarding LD binding, selections can be made from the following configurations, thus making possible a different configuration for each RANK. Logical disk configuration: RAID1 (1+1) RAID5 (2+P)/(3+P)/(4+P)/(5+P)/(6+P)/ (7+P)/(8+P)/(9+P)/(10+P)/(11+P)/ (12+P)/(13+P)/(14+P) * RAID0 1/3/5/10/15 RAID10 (2+2)/(3+3)/(4+4)/(5+5)/(6+6)/(7+7) Only Windows and Solaris can specify RAID0. However, do not use RAID0 in a highly reliable system (e.g., cluster environment) because RAID0 has no redundancy. Logical disks are bound for the 3000/4000 series disk array when it is initially installed.

(a) General Setting y LD Setting The number of LDs and the LD Capacity are specified here. It is also possible to specify either of them. When only the number of LD is specified, the maximum capacity that can be created is automatically calculated. When only the LD Capacity is specified, the maximum number of logical disks that can be created is calculated. If having specified LD Capacity, you can either enter a numeric value or specify a bound logical disk. To bind logical disks having the same capacity as for a bound one, you should select [Only specify LD capacity]. Logical disks having the same capacity are necessary for using the data replication function*. Clicking the [Reference] button in Figure 8-16 displays the screen below. Figure 8-17 LD Specification Screen The figure shows an example of binding logical disks by selecting 10 GB of free space for the RANK of RAID5 (3+P). Selecting a logical disk from the list makes it possible to bind another logical disk having the same capacity as that selected one. If a logical disk cannot be selected, the “Not Specify Reason” field displays one of the reasons: IV-116 Chapter 8 Disk Array Configuration Setting (S100/S1100/S1200/S1300/S2100/S2200/S2300) y Excess of capacity: The capacity of this logical disk exceeds the free space of the RANK. y Capacity unit disagreement: No logical disk can be bound that will have the same capacity as this logical disk. For detailed reasons for capacity unit disagreement or information on binding logical disks having a different configuration from the already bound RAID configuration, refer to Appendix D “Notes on Use for Data Replication”. The logical disk number selection in the LD Bind dialog and the number display item in the LD specification screen can be replaced with logical disk names. For information on the settings, refer to “Client Start/Stop” in the “User’s Manual” or “User’s Manual (UNIX)” in accordance with the OS in use. Note that, if the detailed display is selected for the LD specification screen, the display order of the numbers and logical disk names in the list is changed. * (b) Refer to the “Data Replication User’s Manual (Function Guide)” (IS015) for the data replication function.

At Cross Call ON, this setting is disabled; however, settings are made with controller 0. on the Cross Call, refer to 8.5.1 “Cross Call and Auto Assignment”. For information For information on the LD Ownership, refer to 8.5.2 “Ownership”. (c) Setting LD Type/Name For the logical disks to be bound, it is also possible to simultaneously set its type and name. The LD name needs to be unique in the system (no two names are allowed). Therefore, when binding two or more logical disks, LD names consisting of a specified character string to which a sequence number is a sequential number is added are automatically given. Example: DiskName0000, DiskName0001, DiskName0002 ... The details of item are the same as (G) “Setting LD Type/Name” of 8.2.4 “Logical Disk Batch Setting”.

Please be careful about it. If the data in use are necessary, select unused physical disks or bind logical disks newly from unused physical disks through individual bind. There are the following four logical disk configurations which can be selected. • High reliability: RAID1 (1+1) Consisting of two PDs, the RANK Capacity is the same as that of about one PD. • Standard: RAID5 (4+P) Consisting of five PDs, the RANK Capacity is the same as that of about four PDs. • Large capacity: RAID5 (6+P) Consisting of seven PDs, the RANK Capacity is the same as that of about six PDs. • Huge capacity: RAID5 (8+P) Consisting of nine PDs, the RANK Capacity is the same as that of about eight PDs. The LD Batch Binding refers to bind multiple logical disks in a batch in accordance with simple parameter instructions such as the RAID type and the number of logical disks. The procedure and precautions for its execution are described below. To collectively bind logical disks, selecting all physical disks, first unbind all configurations already made. Therefore, please note that all the RANKs and logical disks that are already bound will be unbound. (1) Execution procedure The procedure for Batch Binding of logical disks is as follows. The screen transition is shown in Figure 8-21. (i) Select the disk array from the iSM client main screen and then start [Configuration] from the menu or from the toolbar. (ii) Click [Setting] from the “Select Operation Mode” dialog. (iii) Click the [LD Bind] button on “Configuration- [Setting Mode]” to display the LD Batch Binding screen. (For details of the LD Batch Binding screen, refer to 8.2.4 (5) “LD Batch Binding screen”.) (iv) Set the necessary item on the LD Batch Binding screen and then click the [OK] button to output the LD Batch Binding Confirmation screen.

Therefore, if any one of the following conditions is met, the batch binding cannot be executed. (i) Logical disks managed by the Access Control (Port mode) are present. (ii) Logical disks managed by the Access Control (WWN mode) are present. (iii) Logical disks that are set in pairs are present. Execute the batch binding after unset the states above. (3) Disk relationship When binding logical disks, it is necessary to understand the relationship between the physical disk, the RANK, and the logical disk. Figure 8-22 shows the relationship between the physical disk, the RANK, and the logical disk. Physical Disks (PDs) The unit of physical disks comprising a RAID is called RANK. The capacity of a RANK is not a simple total of physical disk capacities but varies with the RAID type. RANK Logical disks are bound in the RANK. Multiple logical disks can be created in a single RANK. Logical Disks (LDs) Figure 8-22 Disk Relationship Diagram (4) Complement In the batch binding, it is executed from RANK Bind to LD Bind all at once. In this case, both the RANK and the LD are bound with the same capacity. Regarding the RANK binding, four patterns based on the combinations of the PD count and the RAID type can be specified. However, when binding through other settings, refer to 8.2 “Method of Binding Logical Disks”. The screen displayed when binding logical disks in a batch and the details are described below. IV-123 Chapter 8 Disk Array Configuration Setting (S100/S1100/S1200/S1300/S2100/S2200/S2300) (5) LD Batch Binding screen The LD Batch Binding screen is shown in Figure 8-23. The displays and setting items in the screen are described below. (A) (B) (C) (D) (E) (F) (G) Figure 8-23 (A) LD Batch Binding Screen PD Group Number The PD group of LD Batch Binding is specified here. The PD groups existing in the disk array are displayed in the pull-down list. Select one from the list. The PD group refers to a management aggregate of PDs; therefore, it is impossible to form a configuration spanning two or more PD groups. (B) Binding logical disks shall be set within this PD group.

The number of displays is automatically calculated depending on the disk array setting state as well as the set values of spares and LDs. (D) Setting Spare Specifies the number of spares. The set value up to twice as many as the DE count can be specified. the maximum value varies with the number of spare binding target physical disks. is 2, the specifiable range is 0 to 4 and the initial value is 2. However, For example, if the DE count Since there are up to 8 spares per PD group, the upper limit of the set value is 8 when the DE count is 4 or more. Up to two spares can be created for a disk enclosure (DE). DEs are physical components of the disk array on which physical disks are mounted. When binding unused physical disks, the maximum value varies with the number of spares that have already been bound. (E) Setting RANK Specifies the RAID type of the RANK to bind. This setup and the PD capacity determine the RANK capacity. • High Reliability RAID1 (1+1): Consisting of two PDs, the RANK capacity is equivalent to that of about one PD. • Standard RAID5 (4+P): Consisting of five PDs, the RANK capacity is equivalent to that of about four PDs. • Large Capacity RAID5 (6+P): Consisting of seven PDs, the RANK capacity is the same as that of about six PDs. • Huge Capacity RAID5 (8+P): Consisting of nine PDs, the RANK capacity is the same as that of about eight PDs. Initial setting is set as “Standard RAID5 (4+P)”. IV-125 Chapter 8 Disk Array Configuration Setting (S100/S1100/S1200/S1300/S2100/S2200/S2300) (F) Setting LD Specifies the number of LDs to bind or their capacity (or both). • Only specify the number of LDs The maximum capacity that can be created is automatically calculated for the individual LD Capacity. Since, in this case, the number of LDs to bind in a RANK is specified, the number of actually bound LDs is the specified value multiplied by the RANK count. • Only specify LD capacity The maximum number that can be created is automatically calculated for the number of LDs to be bound in the RANK. Information such as the number of LDs that are finally bound and their capacity can be checked with 8.2.4 (6) “Confirm LD Batch Binding screen” after clicking the [OK] button. • Specify both the number of LDs and LD capacity Any value can be set to the number of logical disks/capacity. The acceptability of the set value is verified after the [OK] button is clicked. 1. If the set value is in error, an error message is output. The capacity which is entered into the input field can be used by the user. However, depending on the input value and the RAID configuration, a capacity exceeding this value may be obtained. The reason is that, since the minimum unit that can be bound in the case of RAID5(n+P) is 128KBxn, disks are bound in terms of rounded-up MBs if the resulting figure cannot be divided. As the area for use in the RANK, there is not only the capacity for use by the user but also the disk management area. 2. The maximum number of LDs which can be bound in the same RANK is 36. (G) Setting LD Type/Name For the LDs to bind, it is possible to set their formats and names simultaneously with their binding. name needs to be unique in the system (no two names must not be the same). The LD Therefore, when binding multiple LDs, the LD names in which the sequential numbers are added to the specified character strings are automatically given. The value initially displayed in the LD name input field is 20 characters which result from adding 4 characters of the logical disk number to 16 characters inherent to the disk array. When the logical disk name is not changed, the above-mentioned initial value is set. When the LD type is not changed, the LD Type is made blank. Example: 0200200000004C518CAC0000, 200000004C518CAC0001, … Moreover, when the LD Type is made blank, the value set before shipment is initially displayed.

Figure 10-6 Path Information Selection The [Link Path] button is enabled only when a single LD Set is selected from the tree view located in the Accessible LD List display area. The linking of path information with an LD Set means the setting of the HBA’s WWPN of the business server that actually accesses logical disks or the setting of the port (in the Port mode) of the disk array to which the business server is connected. The WWPN (World Wide Port Name) set for the HBA of the business server is necessary for determining whether to permit access in the WWN mode in the [Path Link] dialog box. The WWN (World Wide Name) consists of the WWNN (World Wide Node Name) and the WWPN (World Wide Port Name), and is allocated to the HBA (Host Bus Adaptor; also called FC controller) as ID code information inherent to the HBA.

The actual program version is displayed for Version. (2) iSMnetconf command options The following explains the functions of the iSMnetconf command and the corresponding options: -addscsivalidaddress option: Adds the IP address of the monitoring server for which access is permitted. The IP address added with this option takes effect when the access restriction function is enabled (scsiguardinvalid is off). Up to eight of this option, including the chgscsivalidaddress and delscsivalidaddress options, can be specified simultaneously. The total number of IP addresses that can be added per disk array is 8 when SCSI Socket Valid IP addresses, SNMP Trap Transmission IP addresses, and SNMP Valid IP addresses are all combined. 4 Appendix B -arrayname option: Configuration Setting Command Specifies the name of the target disk array. Since the relationship between the disk array name and the special file name (UNIX version) or disk number (Windows version) is obtained from the “volume information data”, it is necessary to confirm that the “volume information data” has been updated to the latest version. For information on how to update the “volume information data”, refer to “volume list command” in the “User’s Manual” or “User’s Manual (UNIX)” in accordance with the OS in use. -chgscsivalidaddress option: Changes the IP address of the monitoring server for which access is permitted. The IP address changed with this option takes effect when the access restriction function is enabled (scsiguardinvalid is off). Up to eight of this option, including the addscsivalidaddress and delscsivalidaddress options, can be specified simultaneously. -delscsivalidaddress option: Deletes the IP address of the monitoring server for which access is permitted. The IP address changed with this option takes effect when the access restriction function is enabled (scsiguardinvalid is off). Up to eight of this option, including the addscsivalidaddress and chgscsivalidaddress options, can be specified simultaneously. -file option: Reads the file storing the settings and sets the service processor. The settings can be made for multiple disk arrays simultaneously. -force option: Forcibly makes settings even during configuration setting by another configuration setup command. -gateway option: Sets a Gateway Address. Specify the Gateway Address in the input format of “aaa.bbb.ccc.ddd” (in decimal). -ipaddress option: Sets the IP Address of the target disk array. Specify the IP Address in the input format of “aaa.bbb.ccc.ddd” (in decimal). -ipcheckinvalid option: Enables the omission of a check on if the IP Address specified in the ipaddress option is already used by another network equipment. The option also enables the omission of a check conducted to see whether any of the IP addresses specified with the ipaddress, subnetmask, gateway, addscsivalidaddress, 5 Appendix B Configuration Setting Command chgscsivalidaddress, and delscsivalidaddress options is invalid. -number option: Specifies the target Service Processor number. -scsiguardinvalid option: Determines whether to validate/invalidate the limit for access from monitoring servers connected through Ether. If “off” is specified, the limit for access from monitoring servers becomes valid, and only monitoring servers at registered IP Addresses are permitted to make access. If “on” is specified, the limit for access from monitoring servers becomes invalid, and monitoring servers at any IP Addresses are permitted to make access. Therefore, be careful in specifying “on” for this option. -specialfile option: Specifies the special file name of the target disk array. The special file name is displayed by the “volume list command”. For details on the command, refer to the “volume list command” explained in the “User’s Manual” or “User’s Manual (UNIX)” in accordance with the OS in use. -subnetmask option: Sets a Subnet Mask. Specify the Subnet Mask in the input format of “aaa.bbb.ccc.ddd” (in decimal). The subnet of the disk array’s IP Address is set by specifying this option. -view option: Displays Service Processor information. If a Service Processor number is specified in the “number” option, the information of only the specified Service Processor is displayed. If the “number” option is omitted, the information of all the Service Processors is displayed.

The initials RAID of “Redundant Arrays of Inexpensive Disks” mean literally “a set of redundant and inexpensive disks”. However, RAID has been generally explained with “Inexpensive” replaced by “Independent” in these days. Large-capacity hard disks were very expensive at that time, but I/O performance was not high enough for the costs. Disk access was a bottleneck in system performance. RAID was created for the following purposes: y Reducing costs by using inexpensive small-capacity disks y Improving performance by concurrently accessing multiple disks y Increasing reliability by adding redundant data RAID levels 1 to 5 are defined in the thesis mentioned above. However, the table below shows the features of RAID0 (striping), RAID1, RAID5, RAID10, RAID50, and RAID6 only. RAID0 (striping) has no redundancy and does not satisfy all requirements for RAID, but it is in wide use. RAID10 is a combination of RAID0 and RAID1. RAID6 can RAID50 is a combination of RAID0 and RAID5. keep redundancy by its double-parity feature even if one physical disk becomes faulty.

If processing is performed concurrently for the physical disks of the RAID, the data transfer time is reduced to 1/(number of PDs) and data can be accessed quickly. Since RAID0 has no redundant data, 100% of the disk capacity is available. However, data cannot be accessed when even a single disk fails. y Quick access y Highest availability of the disk capacity y RAID0 has no redundant data. Thus, it is inaccessible when even a single disk fails. y Since more than one physical disk is used, reliability becomes 1/number of PDs. Since RAID0 has no redundancy, all the data is lost when even a single disk fails. iSM does not recommend RAID0. Use another RAID configuration. 14 Appendix C RAID (2) RAID1 Data Sent from Host Block1 Block 2 Block 1 Block 2 Block 3 Block 4 Block 3 Block 4 Block 5 Block 5 Block 1 Block 2 Block 3 Block 4 Block 5 Physical Disk1 2 This method writes data (sent from the host) onto two disks (or into 2 disk groups). (Mirroring) RAID1 has the same data in dual configuration. Thus, even if one disk fails, the other disk enables access to the data. In comparison with a single disk, RAID1 achieves the equivalent performance in write operation, and up to the double throughput as performance in read operation by accessing two disks containing the same data. RAID1 offers data reliability higher than any other RAIDs do, but redundant data takes up 50% of the disk capacity. y High reliability y No performance deterioration when a single disk fails y Performance in read operation can be up to twice as high as the throughput of a single disk. y Redundant data takes up a half of the disk capacity. 15 Appendix C RAID (3) RAID5 Data Sent from Host Stripe1 Stripe2 Stripe3 Stripe4 StripeN Parity Generation Stripe1 Stripe3 Stripe2 Parity(3,4) Parity(N,N+1) StripeN Physical Disk1 Parity(1,2) Stripe4 StripeN+1 2 Striping Size 3 This method slices data (sent from the host) in certain striping size and distributes the data to the physical disks of the RAID. It also distributes the parity data to the disks. Since RAID5 distributes parity data to multiple disks, it enables concurrent processing at disk access. Thus, RAID5 is suitable for processing which often makes random access to small files in size of several kilobytes. Even if one of the disks fails, access can be made to the parity data. However, performance in read operation lowers in this case. y Concurrent processing by using distributed parity data y Availability of processing which often makes random access y If one of the physical disks constituting logical disks fails, performance in read operation lowers. 16 Appendix C RAID (4) RAID6 Data Sent from Host Stripe 1 Stripe 3 Stripe 2 Stripe 4 Stripe 5 Parity 1 Generation Stripe 6 Stripe N ...

While doing that, it generates two parity data per block and distributes the respective parities into the disks. RAID6 supports double parity, therefore it secures redundancy even if one disk becomes faulty and also ensures accessibility even if two disks become faulty. However, the capability for reading data degrades in case of a disk failure. In addition to that, RAID6 distributes parity data to multiple disks, it enables concurrent processing for access to the disks. Thus, RAID6 is suitable for random access to small files in size of several kilobytes. y Redundancy secured if one physical disk becomes faulty, and high reliability and availability if two disks become faulty. y Concurrent processing by using distributed parities y Suitable for random access y If two physical disks used for the logical disks fail, the capability for reading data degrades. 17 Appendix C RAID (5) RAID10 Data Sent from Host Block1 Block2 Block1 Block1 Block3 Block5 Block3 Block5 Physical Disk 1 2 Block3 Block4 Block2 Block4 Block5 Block2 Block4 3 4 This method slices data (sent from the host) and distributes (RAID0) the data to pairs of mirrored disks (RAID1). Since RAID10 distributes data to multiple disks, it enables concurrent processing and makes quick access. In addition, it has the same data in dual configuration. Even if one of the disks fails, the other disk enables access to the data. Reliability is about 1/n (n: number of paired sets of RAID1 disks) of RAID1 consisting of two disks. Reliability is lower than that of a single RAID1, but it is still high enough. y High reliability y Quick access y No performance deterioration when a single disk fails y Redundant data takes up a half of the disk capacity. 18 Appendix C RAID (6) RAID50 Data Sent from Host Stripe 1 Stripe 2 Stripe 3 Stripe 4 Stripe 5 Stripe 6 Stripe 7 Stripe 8 Stripe 9 Parity Generation Stripe 10 Stripe N Parity Generation Stripe 1 Stripe 2 Parity (1, 2) Stripe 3 Stripe 4 Stripe 5 Parity (5, 6) Stripe 6 Stripe 7 Parity (7, 8) Stripe 8 Parity (9, 10) Stripe 9 Stripe 10 Parity (N, N+1) Stripe N Stripe N+1 Physical Disk 1 2 4 5 6 3 ... Parity (3, 4) Striping Size This method, based on RAID0, slices data sent from the host and distributes the slices into multiple sets of RAID5 physical disks. Since RAID50 distributes data to multiple sets of RAID5 disks, it enables further concurrent processing and provides quicker access. y Concurrent processing for multiple R/W commands y Quick access y If one of the physical disks constituting logical disks fails, performance in read operation lowers. 19 Appendix C RAID C C..22 L Liisstt o off R RA AN NK K--C Co on nffiig gu urraab bllee R RA AIID D T Tyyp peess The table below shows the number of physical disks and the number of RANKs available by the RAID type on the 100/1000/2000 series (not including S400/S1400/S2400).

Specify the capacity of one logical disk in units of 1 GB*1. 2. Now you can select a recommended capacity (already used in the 3000/4000 series disk array) from a pull-down list.

The real capacity of each logical disk includes additional 2 MB region for disk control, which makes it available for the user. On S400/S1400/S2400/S2800, binding a pool may cause the capacity assigned to a pool (pool used capacity) to exceed the capacity of the logical disks. *1: iSM handles 1024 KB as 1 MB. 21 Appendix D Notes on Use for Data Replication *2: When the total capacity of logical disks is less than 0.1 GB, it is represented as 0.1 GB. (2) S series (not including S400/S1400/S2400/S2800 and 3000/4000 series) The user or the system engineer can bind logical disks of the disk arrays (except for S400/S1400/S2400/S2800 and 3000/4000 series). The capacities of logical disks to be bound vary depending on the RAID configuration. If you want to bind logical disks which are to be used with DataReplication, the disks to be paired must have the same capacity. If having purchased or planning to purchase the products such as DataReplication, keep in mind that the following assists in easily updating the system configuration later: y Binding logical disks having the same capacity y Selecting RAID configuration in which logical disks having the same capacity are easy to be bound iSM can also bind logical disks through the CLI (Command Line Interface). However use of GUI is recommended. This appendix mainly explains how to bind logical disks through the GUI. If use of DataReplication is not for binding logical disks, read the description of “RV”*1 as “logical disks having the same capacity” in the explanation below. A logical disk’s capacity smaller than 0.1GB*2 is shown rounded on the configuration setting summary display*3. Note that different capacities may appear to be identical. *1: RV (Replication Volume) is a copy volume in using DataReplication. *2: iSM processes data with 1MB = 1024KB. *3: When the total capacity of logical disks is less than 0.1 GB, it is represented as 0.1 GB. 22 Appendix D Notes on Use for Data Replication D D..22 R Reecco om mm meen nd deed dR RA AIID D C on nffiig gu urraattiio on n Co Table D-1 shows RAID configurations recommended if you want to get logical disks to have the same capacity when using DataReplication.

The section mainly explains the capacities of logical disks which are to be bound in a non-recommended RAID configuration. Use “Individual Setting” of Configuration Setting (GUI) to bind logical disks in a non-recommended RAID configuration. (1) Disk array specifications This disk array series requires that the capacity of a logical disk of the RAID type (RAID0, RAID10, or RAID5) using the striping feature is a multiple of “striping size × number of data disks*”. The striping size for of this disk array series is defined as 128KB. Thus, “128KB × number of data disks” is the capacity unit of logical disks to be bound, as shown in Figure D-1. 128KB x Number of Data Disks Physical Disks Figure D-1 Capacity Unit in Binding *: A data disk is a physical disk, which is used to save data in RAID configuration. The number of data disks is 1 in configuration of RAID1(1+1); it is 4 in configuration of RAID5(4+P). In other words, if a RAID configuration is expressed as RAID5(n+P) or RAID10(n+n), “n” is equal to the number of data disks. 24 Appendix D (2) Notes on Use for Data Replication Specifications common to Configuration Settings (GUI and CLI) Configuration Settings (GUI and CLI) process logical disk capacities in megabytes. According to “(1) Disk array specifications” and common specifications in combination, the capacity unit of logical disks to be bound is the lowest common multiple of “128KB × number of data disks” and “1MB (= 1024KB)” as shown in Table D-2. Table D-2 Capacity Unit of Logical Disks to be Bound Number of Data Disks 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Capacity Unit (MB) 1 3 1 5 3 7 1 9 5 11 3 13 7 15 If RAID such as RAID1, which does not use the striping feature, is in use, data is processed in megabytes. Thus, the capacity unit is “1”. If a capacity is specified, the system recognizes it as the capacity that the user can use. In this case, logical disks are bound in the specified capacity + 2MB (disk management area). (3) Specifications specific to Configuration Setting (GUI) Configuration Setting (GUI) specifies a capacity in units of 0.1GB. with 0.1GB = 1024MB/10. The capacity is calculated In this case, obtain the capacity as follows: y With Capacity Specification (Individual Setting): Specified capacity × 1024 → (Decimal places rounded up)*1 → (+2MB)*2 → (Alignment)*3 → Capacity of LD to be bound y With Disk Count Specification (Individual Setting): Free space in RANK/specified number of data disks → (Decimal places rounded up) → (Alignment)*3 → Capacity of LD to be bound *1: The value with decimal places being rounded up ensures that the specified capacity is allocated from the free space in a selected RANK. If the RANK does not contain free space large enough, logical disks cannot be bound. *2: A disk management area is added. *3: Alignment means obtaining a multiple (an outer value for Capacity Specification, and an inner value for Disk Count Specification) of the capacity (in megabytes) calculated from Table D-2. 25 Appendix D (4) Notes on Use for Data Replication Examples of obtaining capacities of LD to be bound through Individual Setting of Configuration Setting (GUI) The following are examples of capacities obtained by specifying a capacity or the number of data disks when logical disks are bound. Refer to D.3.3 “Method of Specifying Configuration Setting” for details on “Capacity Specification” and “Disk Count Specification”. Examples 1: Binding with Capacity Specification 1. Capacity obtained when logical disks are bound with 1.1GB specified for RAID5 (4+P): 1.1GB × 1024 = 1126.4MB → (Decimal place rounded up) → 1127MB → (+2MB)*1 → 1129MB → (Alignment) → 1129MB 2. Capacity obtained when logical disks are bound with 1.1GB specified for RAID5 (3+P): 1.1GB × 1024 = 1126.4MB → (Decimal place rounded up) → 1127MB → (+2MB)*1 → 1129MB → (Alignment) → 1131MB *1: Logical disks are bound in the user-specified capacity + 2MB as the disk array management area. Examples 2: 1. Binding with Disk Count Specification Capacity obtained when three logical disks are bound with 266.7GB as the capacity of RAID5 (4+P): 266.7GB × 1024/3 = 91033.6MB → (Decimal place rounded down) → 91033MB → (Alignment)*1 → 91033MB*2 2. Capacity obtained when three logical disks are bound with 200GB as the capacity of RAID5 (3+P): 200GB × 1024/3 = 68266.66MB → (Decimal places rounded down) → 68266MB → (Alignment)*1 → 68265MB*2 *1: The capacity unit is aligned according to Table D-2. In RAID5, (13+P) is the greatest, and the maximum value (MB as the capacity unit) is 13MB. *2: The capacity of the bound logical disks includes 2MB as the disk array management area. 26 Appendix D Notes on Use for Data Replication Note that the logical disk capacity displayed by the iSM is that available to the user, not the total capacity including the disk array management area. 27 Appendix D Notes on Use for Data Replication D D..33..22 D Deettaaiilleedd C Coom mbbiinnaattiioonn ooff R RA AIID D C Coonnffiigguurraattiioonn This disk array series defines that the capacity unit of logical disks to be bound depends on the RAID configuration. Therefore, RV may not be bound in RAID configuration different from that of MV. Table D-3 shows the combinations of RAID configurations in which RV having the same capacity as for MV can be bound.

The number of data disks is 1 in configuration of RAID1(1+1); it is 4 in configuration of RAID5(4+P). In other words, if RAID is expressed as RAID0(n), RAID5(n+P), or RAID10(n+n), “n” is equal to the number of data disks shown in Table D-3. [How to read the table] The table shows RAID configurations (depending on the number of data disks in actual operation) in which RV having the same capacity as for MV can be bound. The symbols in the table are as follows: ~: RV can be bound. {: Configuration Setting (GUI) may be unable to bind RV depending on the MV capacity. In this case, use Configuration Setting (CLI) to bind RV. ∆: Both Configuration Setting (GUI) and Configuration Setting (CLI) may be unable to bind RV depending on the MV capacity. Examples: 1. With MV bound in configuration of RAID5(4+P) Configuration Setting (GUI) can bind RV in configuration of RAID1, RAID5(2+P, 4+P, 8+P), RAID10(2+2, 4+4), or RAID0(1). 2. With MV bound in configuration of RAID5(6+P) Configuration Setting (GUI) can bind RV in configuration of RAID0(3), RAID5(3+P, 6+P, 12+P), or RAID10(3+3, 6+6). Configuration Setting (CLI) can bind RV in configuration of RAID1, RAID5(2+P, 4+P, 8+P), or RAID10(2+2, 4+4). 28 Appendix D Notes on Use for Data Replication D D..33..33 M Meetthhoodd ooff S Sppeecciiffyyiinngg C Coonnffiigguurraattiioonn S Seettttiinngg There are two methods (Batch Setting and Individual Setting) for binding logical disks through Configuration Setting (GUI). Each method includes another three specification methods “Disk Count Specification”, “Capacity Specification”, and “Disk Count and Capacity Specification”. There are six specification methods in total. As a rule, bind RV by the same specification method as when binding MV. Table D-4 shows the combinations of specification methods.

If there is difference between capacities obtained by the combinations of specification methods in Table D-4, the capacity of a logical disk varies depending on the specification method. Table D-5 shows the capacities of bound logical disks for each specification method. 29 Appendix D Notes on Use for Data Replication Table D-5 Setting Method Bound LD Capacity by Specification Method Specification Method How to Obtain Capacity Disk Count Specification Batch Setting Individual Setting Capacity Specification*1 Disk Count and Capacity Specification*1 Disk Count Specification Capacity Specification*1 Disk Count and Capacity Specification*1 Divide the recommended maximum capacity*2, which is within the RANK capacity, by the number of data disks.

Thus, the capacity of the bound logical disk is the same as when it is obtained by “Capacity Specification”. *2: Recommended capacity = 2128MB × n (n = 1, 2, 3, ...) If the RANK capacity is 266.7GB (= 273100.8MB), the recommended capacity is 2128MB × 128 = 272384MB. *3: A capacity must be specified in units of 0.1GB (0.1GB = 1024MB/10). Examples 1: 1.

Dynamic pool The minimum unit of assigning an area in a dynamic pool is 256 MB, and the 2-MB control region is secured in another place. Therefore, when the number of disks is 128 or less, the amount of the control region secured in the pool is 256 MB, and when the number of disks is between 129 and 256, it is 512 MB. (1) Formula Use the following formula to calculate the pool used capacity when the capacity of logical disks (user available capacity) required is X (MB) and the number of logical disks is Y: Pool used capacity = ([(X - 1)/256] + 1) × 256 × Y + ([(Y - 1)/128] + 1) × 256 (X,Y > 0) [X] is a gaussian which represents an integer below X. (2) Examples When you bind one 2.0-GB logical disk, the pool used capacity required is: ([(2048 - 1)/256] + 1) × 256 × 1 + ([(1 - 1)/128] + 1) × 256 = 2048 + 256 = 2304 MB When you bind one logical disk with the recommended capacity 2.0 GB, the pool used capacity required is: ([(2126 - 1)/256] + 1) × 256 × 1 + ([(1 - 1)/128] + 1) × 256 = 2304 + 256 = 2560 MB 32 Appendix E (3) List of samples No. of Logical Disks (4) Logical Disk Used Capacity Capacity Pool Used Capacity 1 2.0 GB 2.25 GB (2.2 GB on iSM) 129 2.0 GB 258.50 GB (258.5 GB on iSM) 1 Recommended capacity 2.0 GB 2.50 GB (2.5 GB on iSM) 129 Recommended capacity 2.0 GB 290.75 GB (290.7 GB on iSM) Supplementary explanation For the capacity of logical disks you can bind in unused space, it depends on how many logical disks are in the pool. For example, when you bind 127 logical disks and if there is a pool whose unused space is 2.0 GB, you can locate one 2.0-GB logical disk in the pool, but you cannot locate two 1.0-GB logical disks; because the control region already assigned is used for the 128 logical disks, but a 256-MB new control region is required for 129-th and later logical disks. 2. Basic pool A basic pool consists of multiple partitions in a RAID configuration, and the partitions are assigned by units of 1 MB. Therefore, because the partitions need to be equally used on area assignment to logical disks, the capacity occupied is a multiple of the number of partitions multiplied by 1 MB. (1) RAID1 - 1 partition RAID5 - 1 partition RAID10 (4 PDs) - 2 partitions RAID10 (8 PDs) - 4 partitions RAID10 (16 PDs) - 8 partitions RAID50 (10 PDs) - 2 partitions RAID50 (20 PDs) - 4 partitions Formula Use the following formula to calculate the pool used capacity when the logical disk capacity (user available capacity) required is X (MB) and the number of RAID partitions is N: Y = (X + 2) mod N When Y = 0, Pool used capacity = X + 2 33 Appendix E Logical Disk Used Capacity When Y > 0, Pool used capacity = X + 2 + N - Y A mode N is a congruence representing the remainder of A divided by N. (2) Examples When you bind 1.0-GB logical disks with RAID10 (16 PDs): Y = (1024 + 2) mod 8 = 2 Pool used capacity = 1024 + 2 + 8 - 2 = 1032 MB When you bind 1.0-GB logical disks with RAID10 (8 PDs): Y = (1024 + 2) mod 4 = 2 Pool used capacity = 1024 + 2 + 4 - 2 = 1028 MB When you bind 1.0-GB logical disks with RAID5 (10 PDs): Y = (1024 + 2) mod 2 = 0 Pool used capacity = 1024 + 2 = 1026 MB Note that the logical disk capacity is the same in the respective cases but the pool used capacity is not. 34 Appendix F Appendix F Batch Setup File Batch Setup File F F..11 N Niicckkn naam mee S Seettttiin ng gF Fiillee You can collectively set nicknames using the nickname setting file. The following shows the format of the nickname setting file and a setting sample. (a) Formatting the user definition file The format for batch setting the disk array name, LD type/name and the port name from the user definition file is described below. The user definition file contains a line starting with “#” or “;” to be handled as a comment line. [User definition file format for batch setup] # Comment line rmon name list (A) [array] (B) Target disk array name and new disk array name [ld] (E) nnnnh, new LD type and new LD name (F) : [port] (G) mmh-ssh, and new port name (H) : [array] (B) : (C), (D) (A) Key information (File identification info) Describes “rmon name list” as the key information indicating that the following parameter is the name setting file. (B) Key information (Disk array) Describes key information for specifying the name of the target disk array. The information following the [array] key is valid for the disk array name specified by the [array] key until the next [array] key appears. Only one disk array name can be set by using one [array] key. To set multiple disk array names, an [array] key is required for each disk array name. If multiple disk array names are specified by using one [array] key, only the first disk array name is valid. When an invalid disk array name is specified, the settings are invalid until the next [array] 35 Appendix F Batch Setup File key. (C) Target disk array Name Describes the disk array name (up to 32 alphanumeric characters) targeted by the following parameter, to continue from the key information [array]. (D) New disk array Name Describes the disk array name to set following the target disk array + ‘, (comma)’ when executing the disk array name setting. It is unnecessary to specify this when the disk array name is not to be set (i.e., when changing only the LD type/name or the port name). Describing a name in excess of 32 characters for the disk array name will end in error. (E) Key information (LD) Describes [ld] as the key information indicating that the following parameter is the setup information for LDs. (The information following [ld] is valid until the next [array] or [ld] appears.) (F) New LD Type/Name Sets the format and LD names for the LDs in the target disk array ((c) above) described before describing this parameter. Describes “nnnnh (nnnn: LD number in four hexadecimal digits)” as the ID information of the target LDs. Describes the newly set format (refer to Table 15-1), “, (comma)” and LD name to continue from “, (comma)”. Describing a name in excess of 24 characters for the LD name will end in error. When making settings for other LDs in the same disk array, describe the information to be set in the same format on the succeeding line. On the ACOS-4 system, make sure that the LD identifier name matches the LD name on the host. (G) Key information (port) Describes [port] as the key information indicating that the following parameter is the setup information related to ports. (The information following [port] is valid until [array] or [ld] appears.) 36 Appendix F Batch Setup File (H) New Port Name Sets the names for the ports in the target disk array ((C) above) described before describing this parameter. Describes “mmh-ssh (mm: director number in two hexadecimal digits; ss: port number in two hexadecimal digits)” as the ID information of the ports. Describes the newly set port name to continue from “, (comma)”. Describing a name in excess of 32 characters for the new port name will end in error. When making settings for other ports in the same disk array, describe the information to be set in the same format on the succeeding line.

If you need to handle ACOS-4 resources, be sure to ask our maintenance personnel first. To protect ACOS-4 against system destruction, the work involved in setting the resources used by ACOS-4 is defined as tasks to be carried out by maintenance personnel. On the other hand, the open system resources are allowed to be set by general users, giving priority to the freedom of work in such cases as changing the settings. Note, however, that a mistake or other inappropriate operation that the general user makes when setting the Access Control in the WWN mode or in the GUI-based Port mode, which has been supported for the disk array which applies program product “AccessControl” beginning with Version 2.1, can result in the destruction of the ACOS-4 system. Starting with Version 2.2, a reinforced guard function has been deployed that guards against Access-Control-related operation’s that can lead to the destruction of the ACOS-4 system. Whenever an operation related to the ACOS-4 resources is requested, a dialog appears indicating that the operations for the ACOS-4 resources by general users are restricted and that a consultation with maintenance personnel is required.
