Remove a disk for replacement
Menu: VolumeManager/Disk/RemoveForReplace
Use this menu operation to remove a physical disk from a disk
group, while retaining the disk name. This changes the state
for the disk name to a "removed" disk. If there are any
initialized disks that are not part of a disk group, you will be
given the option of using one of these disks as a replacement.
Enter disk name [<disk>,list,q,?] list

Any applications using these volumes will fail future accesses.
These volumes will require restoration from backup.
Are you sure you want do do this? [y,n,q,?] (default: n) y
The requested operation is to remove disk esmdg05 from disk group
esmdg. The disk name will be kept, along with any volumes using
the disk, allowing replacement of the disk.
Select "Replace a failed or removed disk" from the main menu
when you wish to replace the disk.
Continue with operation? [y,n,q,?] (default: y) y
Removal of disk esmdg05 completed successfully.

Use this menu operation to disable all access to a disk device
by the Volume Manager. This operation can be applied only to
disks that are not currently in a disk group. Use this operation
if you intend to remove a disk from a system without rebooting.
NOTE: Many systems do not support disks that can be removed from
a system during normal operation. On such systems, the
offline operation is seldom useful.
