378 Administering hot-relocation

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

To use vxdiskadm to remove a disk from the hot-relocation pool

1 Select menu item 12 (Turn off the spare flag on a disk) from the

vxdiskadm main menu.

2 At the following prompt, enter the disk media name of a spare disk (such as

mydg01):

Menu: VolumeManager/Disk/UnmarkSpareDisk

Use this operation to turn off the spare flag on a disk.

This operation takes, as input, a disk name. This is the same

name that you gave to the disk when you added the disk to the

disk group.

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

The following confirmation is displayed:

VxVM NOTICE V-5-2-143 Disk mydg01 in mydg no longer marked as

a spare disk.

3 At the following prompt, indicate whether you want to disable more spare disks (y)

or return to the vxdiskadm main menu (n):

Turn-off spare flag on another disk? [y,n,q,?] (default: n)

Excluding a disk from hot-relocation use

To exclude a disk from hot-relocation use, use the following command:

# vxedit [-g diskgroup] set nohotuse=on diskname

where diskname is the disk media name.

To use vxdiskadm to exclude a disk from hot-relocation use

1 Select menu item 15 (Exclude a disk from hot-relocation use)

from the vxdiskadm main menu.
