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 [,list,q,?] list
Disk group: rootdg

Enter disk name [,list,q,?] rootdisk
The following volumes will lose mirrors as a result of this
operation:
rootvol swapvol
No data on these volumes will be lost.
The requested operation is to remove disk rootdisk from disk group
rootdg. 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 rootdisk completed successfully.
Remove another disk? [y,n,q,?] (default: n) n

Use this menu operation to specify a replacement disk for a disk
that you removed with the "Remove a disk for replacement" menu
operation, or that failed during use. You will be prompted for
a disk name to replace and a disk device to use as a replacement.
You can choose an uninitialized disk, in which case the disk will
be initialized, or you can choose a disk that you have already
initialized using the Add or initialize a disk menu operation.
