Creating a Disk Array Alias

An alias can be created to identify the disk array. The alias provides an alternative to the disk array serial
number and raw device file name that can also be used to identify the array.
Aliasing can be used in a variety of ways to help identify disk arrays in large systems. For example, by
assigning numbers to racks and to the shelf positions within the racks, each disk array can be uniquely
identified using an appropriate alias. If a rack is assigned number 12, the disk array installed on shelf 3 of
the rack could be identified using an alias of R12_S03. This technique simplifies locating the disk array
should it need service.
To create a disk array alias, type:
arraymgr -D alias_name <array-id>
alias_name can be up to 12 characters in length and can include upper case letters, numbers, spaces,
number sign (#), underscore (_), and period (.).
Recover
If the disk array is not shutdown properly, it is possible that the data maps in NVRAM memory will be lost.
For this reason, the disk array allows the data maps to be periodically written to the disk drives. If the maps
are lost, an error code such as "No Address Table" will appear on the display. If your disk array is a boot
device, you may have to recover the maps by using the front panel command called "Recover" under the
"Cntrl Changes" menu. The Recover command is only supported in controller firmware versions later than
HP40, and any patch delivered after IPR9808 release.
