To use vxdiskadm to designate a disk as a hot-relocation spare

Select Mark a disk as a spare for a disk group from the vxdiskadm

main menu.

At the following prompt, enter a disk media name (such as mydg01):

Enter disk name [<disk>,list,q,?] mydg01

The following notice is displayed when the disk has been marked as spare:

VxVM NOTICE V-5-2-219 Marking of mydg01 in mydg as a spare disk

is complete.

At the following prompt, indicate whether you want to add more disks as

spares (y) or return to the vxdiskadm main menu (n):

Mark another disk as a spare? [y,n,q,?] (default: n)

Any VM disk in this disk group can now use this disk as a spare in the event

of a failure. If a disk fails, hot-relocation should automatically occur (if

possible). You should be notified of the failure and relocation through

electronic mail. After successful relocation, you may want to replace the failed

disk.

Removing a disk from use as a hot-relocation spare

While a disk is designated as a spare, the space on that disk is not used for the

creation of VxVM objects within its disk group. If necessary, you can free a spare

disk for general use by removing it from the pool of hot-relocation disks.

To remove a spare from the hot-relocation pool, use the following command:

# vxedit [-g diskgroup] set spare=off diskname

where diskname is the disk media name.

For example, to make mydg01 available for normal use in the disk group, mydg, use

the following command:

# vxedit -g mydg set spare=off mydg01
