HP-UX Using the ARM Command Line Utilities for HP-UX Configuring a New Disk Array Configuring a New Disk Array After installing a new disk array, you can perform the initial configuration using the ARM utilities. This establishes the operating environment for the disk array. To configure a new disk array: 1. Plan your capacity management strategy and LUN configuration. Decide how you want to use the disk array capacity. Factors such as data redundancy and performance influence how you manage the capacity. See "Managing the Disk Array Capacity" in the HP SureStore E Disk Array 12H User's and Service Manual for help in planning your strategy. Also see "Tips for Configuring the Disk Array On HP-UX" in Chapter 1 of this guide. 2. Display the serial number of the disk array by typing: arraydsp -i The serial number provides a way to identify disk arrays when using the ARM utilities. Record the serial number for future reference, or set a shell variable to hold this value, for example: export ID=00786B5C0000 or export ID=/dev/rdsk/c2t0d0 3. If the planning in step 1 requires you to disable any of the configuration settings to implement your capacity management strategy, do so now. These settings include Active Hot Spare, Auto Rebuild, and Auto Include. Change the configuration settings by typing: arraymgr -h { on|off } arraymgr -a { on|off } arraymgr -i { on|off } (Active Spare) (Auto Rebuild) (Auto Include) NOTE! Only one setting can be changed on each command line. 37
