HP-UX Using the ARM Command Line Utilities for HP-UX Selecting a Disk Array to Manage Selecting a Disk Array to Manage When using the ARM utilities, the field is used to identify the disk array. The field can contain the disk array serial number, the raw device file name of any LUN on the array, or an alias text string assigned to the array using the arraymgr command. For example, assume a disk array has a serial number of 00786B5C0000, special raw device file /dev/rdsk/c2t0d0 is defined for this array, and it has an alias of autoraid4. To check the available unallocated capacity on this particular disk array, you could use any of the following commands: arraydsp 00786B5C0000 or arraydsp /dev/rdsk/c2t0d0 or arraydsp autoraid4 The serial number of all arrays in the system can be obtained using the command arraydsp -i For more information see "Displaying Disk Array Serial Numbers" in this chapter. A list of all special device filenames assigned to the disk array can be displayed using the following command: ioscan -fn -C disk Many commands affect the operation of the entire disk array, regardless of whether the field contains the array serial number or a special device file name. Commands that involve only a specific LUN on the array will include an option (-L LUN) for identifying the LUN involved. For example, to format LUN 3 on a disk array that is referenced by /dev/rdsk/c2t0d0, you would use the following command: arrayfmt -L 3 /dev/rdsk/c2t0d0 36
