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.
5. Mirror volumes on a disk.
You can mirror volumes on a disk. These volumes can be mirrored to
another disk with available space. Creating mirror copies of volumes
in this way protects against data loss in case of disk failure. Volumes
that are already mirrored or that are comprised of more than one
subdisk will not be mirrored with this task. Mirroring volumes from
the boot disk will produce a disk that can be used as an alternate boot
disk.
6. Move volumes from a disk.
You can move any volumes (or parts of a volume) that are using a disk
onto other disks. Use this menu task immediately prior to removing a
disk, either permanently or for replacement.
NOTE Simply moving volumes off a disk, without also removing the disk, does
not prevent other volumes from being moved onto the disk by future
operations.
7. Enable access to (import) a disk group.
You can enable access by this system to a disk group. If you wish to
move a disk group from one system to another, you must first disable
(deport) it on the original system. Then, move the disks from the
deported disk group to the other system and enable (import) the disk
group there. You are prompted for the disk group name.
8. Disable access to (deport) a disk group
You can disable access to a disk group that is currently enabled
(imported) by this system. Deport a disk group if you intend to move
the disks in a disk group to another system. Also, deport a disk group
if you want to use all of the disks remaining in a disk group for some
new purpose.
You are prompted for the name of a disk group. You are asked if the
disks should be disabled (offlined). For removable disk devices on
some systems, it is important to disable all access to the disk before
