Executing: container split 0
Container 1 created
After running the container split command to split a mirror
set, use the container list command to display information
about the containers, as in the following example. In the example,
the Type column indicates two volume sets with container labels 0
and 1 that reside on SCSI devices 2:01:0 and 2:02:0.

Understanding Splitting a Mirror Set in a UNIX Environment
On UNIX systems, the message displayed after you execute the
container split command includes the root special file
associated with the newly created split container. The name of the
root special file associated with the split container also appears in
the Num Label column of the
container list command.
On UnixWare, before splitting a mirror set that contains a volume
table of contents, run the
edvtoc command and change the
volume label to a series of twelve spaces. You can then use the
container split command to split the mirror set.
Unmirroring a Mirror Set
The CLI allows you to unmirror a mirror set. Unmirroring a mirror
set results in a single-partition volume set and freespace. You use the
container unmirror command to unmirror a mirror set. Note
that there is no equivalent command for a multilevel container of
mirror sets. To unmirror a multilevel container of mirror sets, use the
container unmirror command for each underlying mirror set.
Before unmirroring a mirror set, shut down system applications
(such as databases) to flush application data to the controller.
