Making a disk available for hot-relocation use

Free space is used automatically by hot-relocation in case spare space is not sufficient to relocate failed subdisks. You can limit this free space usage by hot-relocation by specifying which free disks should not be touched by hot-relocation. If a disk was previously excluded from hot-relocation use, you can undo the exclusion and add the disk back to the hot-relocation pool.

To make a disk available for hot-relocation use, use the following command:

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

 To use vxdiskadm to make a disk available for hot-relocation use

  1. Select menu item 16 (Make a disk available for hot-relocation use) from the vxdiskadm main menu.
  2. At the following prompt, enter the disk media name (such as mydg01):

    Menu: VolumeManager/Disk/UnmarkSpareDisk

    Use this operation to make a disk available for hot-relocation

    use. This only applies to disks that were previously excluded

    from hot-relocation use. 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:

V-5-2-932 Making mydg01 in mydg available for hot-relocation

use is complete.

  1. At the following prompt, indicate whether you want to add more disks to be excluded from hot-relocation (y) or return to the vxdiskadm main menu (n):

    Make another disk available for hot-relocation use? [y,n,q,?]

    (default: n)
