The high level process flow for an Offline Mirror Backup is as follows:
v Checks AIX mirror rules for each logical volume specified to be taken offline.
v Checks to make sure that each file system is mounted for each logical volume
specified for the mirror split.
Note: This check does not apply to raw logical volumes.
v Checks to make sure that the jfslog is mirrored for each file system being taken
offline.
v Checks to ensure that no JFS2 file systems have been specified.
Note: JFS2 file systems are not supported for the offline mirror backup process.
However, they may be included in the actual backup command executed
at either a shell prompt or by a Backup Command File

v Checks to ensure that there are no stale physical partitions.
Note: If stale partitions are found, the process will offline mirror process will
issue a warning message and the logical volume containing stale
partitions will not be split. The backup process will continue. You must
use the /usr/sbin/syncvg command to re synchronized the stale. You may
also use the SysBack SMIT fast path smitty sbom_syncvg to perform this
action.
v Display a list of all of the warning and error messages for all logical volumes
that failed the above checks.

errors reported, the Offline Mirror process would terminate at this point.
v If you specified a Pre-Offline script, it would be run at this point.
v Specified raw logical volumes are taken offline and split using the
/usr/sbin/chlvcopy command.
v Specified file systems and their respective logical volumes are split using the
/usr/sbin/chfs command. They are split in alphabetical order by mount
point.This creates a temporary mount point called /sbom/your_filesystem.
v If you specified a Backup Command File, then it would be run at this point. If
you did not, you will be placed at a command prompt where you may issue
your backup command.
v The backup process runs.
v Once the Backup Command File script exits, or the command prompt is exited,
the Offline Mirror process will begin to re synchronized the mirrors.
