Backing Up a Disk Group Configuration
VxVM uses the disk group configuration daemon to monitor the configuration of disk groups,
and to back up the configuration whenever it is changed. By default, the five most recent
backups are preserved. If required, you can also back up a disk group configuration by
running the vxconfigbackup command.
The following table describes the files that record disk group configuration information:
Here diskgroup is the name of the disk group, and dgid is the disk group ID. If a disk group is
to be recreated on another system, copy these files to that system.
CAUTION Take care that you do not overwrite any files on the target system that are used
by a disk group on that system.
To back up a disk group manually, use this command:
# /etc/vx/bin/vxconfigbackup diskgroup
To back up all disk groups, use this version of the command:
# /etc/vx/bin/vxconfigbackup
For more information, see the vxconfigbackup(1M) manual page.
