Add a mirror plex to the volume, specifying disks not used in the first data plex and preferably on different buses:
# volassist [-g disk_group] mirror volume init=active \
layout=nolog disks
The init=active option prevents LSM from synchronizing the plexes. Because the volume is new and contains no data yet, LSM does not need to synchronize the plexes.
The following example creates a mirror plex for the same volume, using disks dsk5, dsk6, and dsk7:
# volassist -g dg1 mirror vol2 init=active \
layout=nolog dsk5 dsk6 dsk7
例：volassist -g rootdg mirror usrvol2 init=active layout=nolog dsk11h
Note
Because two mirrors are used in the volume, 6 GB of free space is needed. Each mirror uses 3 GB of disk space.
The following are examples of the use of the volmirror command.
1. The following command mirrors the contents of the disk named disk01 to
any available space on any available disk. Subsequent calls to volas-
sist will cause created volumes to be mirrored by default.
volmirror -d yes disk01
2. The following command displays the current status of default mirror-
ing. It prints the string yes if mirroring is currently enabled or no,
if not.
volmirror -D
3. The following command mirrors any volumes on disk02 onto disk03.
volmirror disk02 disk03

Mirror volumes on a disk
Menu: LogicalStorageManager/Disk/Mirror
This operation can be used to mirror volumes on a disk. These
volumes can be be mirrored onto another disk or onto any
available disk space. Volumes will not be mirrored if they are
already mirrored. Also, volumes that are comprised of more than
one subdisk will not be mirrored.
