Modular Smart Array 1500 cs Maintenance and Service Guide 51 Diagnostics MSA1000 Controller indicators During normal runtime, the MSA1000 Controller has 16 indicators that indicate activity or malfunction of the controller. They are labeled 1-16, as shown in the following figure. The table that follows describes the purpose and function of each indicator. 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 Figure 31: MSA1000 Controller indicators Table 10: MSA1000 Controller Indicator Descriptions Indicator 52 Function Description 1 Drive failure ON = A configured hard drive has failed in the array 2 Cache activity ON = Cache active OFF = No cache activity Blinking = Cache transfer pending 3 SCSI Bus 1 active ON = Indicates requests are outstanding on the second SCSI bus 4 SCSI Bus 0 active ON = Indicates requests are outstanding on the first SCSI bus 5 Logical I/O active ON = Currently processing logical requests from the Host Adapter 6 Direct Memory Access (DMA) active ON = DMA transfers are active 7 Active/Standby ON=Controller is active OFF=Controller is in standby 8 Idle heartbeat Indicates the array controller is idle and functioning 9-q Busy status ON = Indicates this array controller is idle OFF = Indicates this array controller is operating at full capacity w- y Fibre Channel IDs Modular Smart Array 1500 cs Maintenance and Service Guide Diagnostics MSA1000 Controller display Each array controller in a MSA1500 cs contains an integrated Liquid Crystal Display (LCD). This module is used for displaying informational and error messages, showing the status of the module, and for providing user input when required. Traditional Power-On Self-Test (POST) messages issued by PCI-based array controllers have been combined with runtime event notification messages to create a new set of controller display messages. The display module consists of the following components: ■ A two line, twenty column display text display window ■ Four navigation buttons arranged in a circular “pie” shape ■ Two status indicator lights 1 2 3 7 4 5 6 Figure 32: Controller display \ Controller Display Description 1 Fault indicator (amber) (indicates a component failure or external enclosure failure) 2 Display 3 Left navigation button 4 Up navigation button 5 Right navigation button 6 Down navigation button 7 Redundancy Link indicator (green) Modular Smart Array 1500 cs Maintenance and Service Guide 53 Diagnostics Controller display messages The display module is capable of holding up to 100 messages. After this maximum size is reached, older messages are removed to make room for newer ones. Messages can be of three types: error, informational, and user input. The display message may specify a box number. The following box numbers are defined. ■ Box 1 is the MSA1500 cs chassis. ■ Box 2 is the storage enclosure attached to SCSI port A of the MSA1500 cs. ■ Box 3 is the storage enclosure attached to SCSI port B of the MSA1500 cs. Error messages Error messages indicate that a problem has occurred and may require user action to correct it. A complete list of possible messages and their meanings is contained in this chapter. An amber indicator to the left of the LCD display is turned on when an error message is currently displayed. This indicator is turned on if an error message was sent to the display module but has not been viewed because non-error type messages were sent to the display module afterwards. By scrolling backward and viewing all error messages, the indicator will reset and light when currently on an error message. Informational messages Informational messages indicate non-critical changes in the system that are provided as feedback to the user. A complete list of possible messages and their meanings is contained in this chapter. The amber indicator to the left of the LCD display is off whenever an informational message is currently being viewed unless an unviewed error message was previously sent to the display module. By scrolling backward and viewing all error messages, the indicator will return to only lighting up when currently on an error message. User input messages User input messages indicate that the system has encountered a situation that allows user input. The user can select from a number of choices. If the user does not select one of the choices in a set amount of time, the system will select the default setting. These user input messages will only occur during system power on and not during run time. A complete list of possible messages and their meanings is contained in this chapter. The amber indicator to the left of the display text display window will blink on and off when a user input message is currently being viewed and is available for input. If the user has not provided input within the time-out period, the message will remain but the indicator will stop blinking. Scrolling Older messages can be viewed by scrolling backward using the up navigation button (with the up arrow on it). Messages that are more recent can be viewed by scrolling forward using the down navigation button (with the down arrow on it). The last message can be viewed by pressing the left navigation button. When a new message is sent to the LCD, the display shows that message and ignores any previous scrolling position. This new message is now the most recent message available. 54 Modular Smart Array 1500 cs Maintenance and Service Guide Diagnostics Deleting messages The currently displayed message can be deleted from the display module by pressing the left navigation button and the right navigation button at the same time. Redundancy link light There is a green indicator to the left of the LCD display that is lit when two array controllers are inserted into the MSA1500 cs with controller redundancy enabled. The indicator is not lit if only one array controller is inserted or if the array controllers are not redundant due to some type of failure. Note: You must have redundant cables connected to enable redundancy.

It is always preceded by message #72 (although message #72 is removed from the LCD display once it has accepted user input). Modular Smart Array 1500 cs Maintenance and Service Guide Action The no option will cause the array controller to halt itself, providing the user an opportunity to resolve the issue. Selecting the yes option will result in the cache data being erased. Operation of the array controller will continue normally. 63 Diagnostics Table 11: LCD Message Descriptions Message 72 CACHE ERROR IGNORE? <=NO >=YES 64 Type User Input Description Action During power up, data was found in the cache that could not be flushed to the drives. The reason is either because the data does not belong to this array controller (the cache board was moved from a different array controller) or the cache data is partial (the rest of the data is in another cache board that was removed from the array controller). This error could occur if cache boards are moved improperly. The no option will cause the array controller to halt itself, providing the user an opportunity to resolve the issue. Selecting the yes option will result in the cache data being erased. Operation of the array controller will continue normally. Error 1.1 and 1.2: There is only one cache board in the array controller at present but it was previously configured with a second cache board that is now missing (dual cache module configuration). Error 2.1 and 2.2: A second cache board that contained valid data was removed from its original array controller and added to this array controller (dual cache module configuration). Error 2.3: A cache board that contained valid data was removed from its original array controller and added to this array controller (single cache module configuration). Return all cache boards to their original array controllers. Power up the systems without allowing any host I/O and wait for the cache data to be written to the drives. This will take a few minutes after the systems have finished the power on sequence. The systems can be powered off and cache boards moved to their new locations.

If the status does not change to OK, check cables, fibre bay board, SFP, and HBA. 517 FIBRE SUBSYSTEM LINK OK Informational There is an active fibre connection to this MSA1000 array controller (Laser On). This message is only displayed when preceded by message 516. 518 PERSISTENT MEM ENABLED Informational Global variables such as system prompts and profile information remain persistent in cache over power cycles of the MSA1500 cs. This message is displayed each time the MSA1500 cs is powered up. Modular Smart Array 1500 cs Maintenance and Service Guide 75 Diagnostics Recovery ROM and ROM cloning Recovery ROM Each MSA1000 Controller contains ROM (Read-Only Memory), which holds the firmware that operates the controller. The Recovery ROM feature stores two complete firmware images in the ROM: one active image and one backup image. When the controller is powering up, it checks both firmware images to ensure they are valid. If either is not, the valid image will be copied on top of the invalid image to correct it. This is referred to as auto-flashing. All of this functionality is done automatically by the controller and does not require any user intervention. ROM cloning In order for a MSA1500 cs to operate in a redundant controller configuration, it must contain two controllers that are executing the same version of firmware. During power up (or if an optional controller is hot-plugged while the MSA1500 cs is already operating) the firmware versions on both controllers are compared. If they are not the same, then the ROM Cloning feature will attempt to copy one version of firmware onto the other controller. After the copy has been completed, the controller that was modified will be automatically reset. Once the reset controller has powered up the two controllers should then start redundant operation. All of this functionality is done automatically by the controllers and does not require any user intervention. On initial power up, the controller in the right slot is considered the primary controller and the version of firmware on that controller is cloned. If a failed controller is replaced, the controller still in operation is considered the primary controller and the version on that controller is cloned. There is the possibility that a specific version of firmware may not be compatible with certain hardware revisions of a controller. In this scenario, the most recent firmware version that is compatible with both controllers will be copied to the controller with the incompatible firmware version. However, if the controller that is updated is already operating and processing I/O, then it will not be reset. The MSA1500 cs will not enter redundant operation and an appropriate message will be shown on the display. After the MSA1500 cs has been shutdown and powered back on, the controllers will then be able to enter redundant operation. On a subsequent power cycle, both controllers will enter redundant mode. 76 Modular Smart Array 1500 cs Maintenance and Service Guide Connectors and Indicators 4 Overview This chapter provides figures and tables showing front and rear views and the locations of connectors and indicators on various parts of the HP StorageWorks MSA1500 cs.

To prevent electrostatic damage, observe the following precautions: ■ Avoid hand contact by transporting and storing products in static-safe containers. ■ Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations. ■ Place parts on a grounded surface before removing them from their containers. ■ Avoid touching pins, leads, or circuitry. ■ Always make sure you are properly grounded when touching a static-sensitive component or assembly. Modular Smart Array 1500 cs Maintenance and Service Guide 93 Electrostatic Discharge Grounding methods There are several methods for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts: ■ Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm ± 10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin. ■ Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats. ■ Use conductive field service tools. ■ Use a portable field service kit with a folding static-dissipating work mat. If you do not have any of the suggested equipment for proper grounding, have an Authorized HP Reseller install the part. Note: For more information on static electricity, or assistance with product installation, contact your HP Authorized Reseller. 94 Modular Smart Array 1500 cs Maintenance and Service Guide Specifications C This chapter provides operating and performance specifications for the HP StorageWorks MSA1500 cs.
