Command Control Interface User and Reference Guide xx Chapter 1: Overview This chapter provides an overview of the Command Control Interface (CCI) software and CCI operations on the Hitachi RAID storage systems. About Command Control Interface The Command Control Interface software enables you to perform storage system configuration and data management operations by issuing commands to the RAID storage systems: ■ Hitachi Virtual Storage Platform G200, G400, G600, G800 ■ Hitachi Virtual Storage Platform F400, F600, F800 ■ Hitachi Virtual Storage Platform F1500 (VSP F1500) ■ Hitachi Unified Storage VM (HUS VM) ■ Hitachi Virtual Storage Platform (VSP) ■ Hitachi Universal Storage Platform V/VM (USP V/VM) ■ Hitachi TagmaStore Universal Storage Platform (TagmaStore USP) ■ Hitachi TagmaStore Network Storage Controller (TagmaStore NSC) ® ® CCI continues to provide the proven functionality that has been available for the USP V/VM and previous storage system models, including in-system replication, remote replication, and data protection operations. In addition, CCI for VSP and later provides command-line access to the same provisioning and storage management operations that are available in the GUI software (for example, Hitachi Command Suite, Storage Navigator). CCI commands can be used interactively or in scripts to automate and standardize storage administration functions, thereby simplifying the job of the storage administrator and reducing administration costs. Note: If a storage system rejects CCI commands, verify the software licenses for the storage system (for example, TrueCopy) and the status of the software product and storage system. Chapter 1: Overview Command Control Interface User and Reference Guide 21 CCI functions CCI functions CCI functions matrix The following table lists and describes the CCI functions available on the RAID storage systems. Storage system Function TagmaStore USP/ TagmaStore NSC USP V/VM VSP VSP G1x00 VSP F1500 HUS VM VSP Gx00 models, VSP Fx00 models Local copy (open) Yes Yes Yes Yes Yes Yes Local copy (mainframe) No No Yes* No Yes No Remote copy (open) Yes Yes Yes Yes Yes Yes Remote copy (mainframe) No No Yes* No Yes No Data protection Yes Yes Yes Yes Yes Yes VSS configuration Yes Yes Yes Yes Yes Yes SRM SRA Yes Yes Yes Yes Yes Yes Provisioning (raidcom) No No Yes Yes Yes Yes Out-of-band method No No Yes Yes Yes Yes User authentication No No Yes Yes Yes Yes LDEV nickname No No Yes Yes Yes Yes LDEV group No No Yes Yes Yes Yes Resource group No No Yes Yes Yes Yes Resource lock No No Yes Yes Yes Yes *If DKCMAIN microcode version of the VSP storage system is 70-03-3x-xx/xx or later, the operation of TrueCopy for Mainframe, Universal Replicator for Mainframe, and ShadowImage for Mainframe can be performed from Command Control Interface. Chapter 1: Overview Command Control Interface User and Reference Guide 22 Provisioning functions Provisioning functions The raidcom configuration setting command enables you to perform provisioning functions, such as setting commands or creating LDEVs, from CCI. For information about the configuration setting command (raidcom command), see Provisioning operations with CCI (on page 175) . Asynchronous command processing For the raidcom configuration setting commands, asynchronous command processing is used for operations that take time to process on the storage system. Once an asynchronous command has been issued, you can execute additional commands without having to wait for the asynchronous command to complete. You can also monitor the completion status of asynchronous commands by using a status reference command (for example, raidcom get command_status). Command execution modes CCI provides two command execution modes: ■ Transaction mode, in which a script file is specified with the -zt option ■ Line-by-line mode, in which commands are executed row-by-row for the configuration setting (raidcom) commands Chapter 1: Overview Command Control Interface User and Reference Guide 23 Precheck function You can use transaction mode to execute the following checking: ■ Context check: This check is executed when a script file is specified by -zt option. It checks the context of preceding commands and determines whether a subsequent command can be executed. Specifying example: raidcom -zt ■ Configuration check: This check verifies that the actual storage system configuration is valid (implemented) for the resources specified in the commands (for example, LDEVs, ports, pools). Syntax example: raidcom get ldev -ldev_id -cnt 65280 -store raidcom -zt -load Precheck function CCI provides a precheck function for the configuration setting (raidcom) commands that checks the command before it is executed. In earlier versions of CCI, an error was returned when the syntax of a command to be executed was not correct. The precheck function checks the command syntax before the command is executed. To use the precheck function, specify either the -checkmode precheck option or the -zt option. The following table shows the summary of the checking function combinations between the precheck function and the transaction mode.
