Backing Up and Restoring Disk Group Configurations
Chapter 560
If such errors occur, you can restore the disk group configuration from a backup after you have
corrected any underlying problem such as failed or disconnected hardware. Configuration
data from a backup allows you to reinstall the private region headers of VxVM disks in a disk
group whose headers have become damaged, to recreate a corrupted disk group configuration,
or to recreate a disk group and the VxVM objects within it. You can also use the configuration
data to recreate a disk group on another system if the original system is not available.
NOTE Restoration of a disk group configuration requires that the same physical disks
are used as were configured in the disk group when the backup was taken.
The following sections describe how to back up and restore disk group configurations.
