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 <array-id> field is used to identify the disk array. The <array-
id> 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
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 <array-id> 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
