2.3 Remove a disk

This option is used to remove a disk from a disk group provided there is no active volume using this disk .. If there are some volumes using the disk the those have to be either moved to some other disk or removed if they are no longer needed.

However since a diskgroup must have at least one disk you can not remove all the disks from a disk group . To remove all disks from a diskgroup you have to disable the volume group with the exception of rootdg disk group which can not be disabled .

Select menu item 3 (Remove a disk) from the vxdiskadm main menu.

Remove a disk
Menu: VolumeManager/Disk/RemoveDisk

Use this operation to remove a disk from a disk group. 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 [,list,q,?] disk01

Requested operation is to remove disk disk01 from group rootdg.

Continue with operation? [y,n,q,?] (default: y)

Removal of disk disk01 is complete.

Remove another disk? [y,n,q,?] (default: n)

2.4 Remove a disk for replacement

This option is used for removing the disk but retaining the name of the disk so that it can be used by the newly replaced disk . The replacement disk can be a newly added disk or already available disk in the other disk groups

Remove a disk for replacement
Menu: VolumeManager/Disk/RemoveForReplace
