HP Surestore Disk Array 12h and FC60 - Manual (Page 296)

296 Managing the Disk Array Using Array Manager 60
Adding a Global Hot Spare
A global hot spare is added using an unassigned disk. If there are no unassigned disks
available, you cannot add a global hot spare unless you install a new disk or unbind an
existing LUN.
To add a global hot spare, type:
ammgr -h channel:ID
Command Example
The following example adds a global hot spare using disk 1:1 on disk array 0000005EBD20.
ammgr -h 1:1 0000005EBD20
Removing a Global Hot Spare
If you need to increase the available capacity of your disk array, you can do so by removing
a global hot spare. The global hot spare will be added to the unassigned disk group and can
be used to bind a LUN. However, the loss of the global hot spare may make your disk array
more vulnerable when a disk failure occurs.
To remove a global hot spare, type:
ammgr -d channel:ID
Command Example
The following example removes disk 2:3 as a global hot spare on disk array rack_51.
ammgr -d 2:3 rack_51
