Veritas Volume Manager 5.0.1 Troubleshooting Guide, HP-UX 11i v3, First Edition, November 2009

vxconfigbackup and vxconfigrestore, are provided for backing up and restoring

a VxVM configuration for a disk group.

When importing a disk group, any of the following errors indicate that the disk

group configuration and/or disk private region headers have become corrupted:

VxVM vxconfigd ERROR V-5-1-569 Disk group group,Disk disk:Cannot

auto-import group: reason

The reason for the error is usually one of the following:

Configuration records are inconsistent

Disk group has no valid configuration copies

Duplicate record in configuration

Errors in some configuration copies

Format error in configuration copy

Invalid block number

Invalid magic number

If VxVM cannot update a disk group’s configuration because of disk errors, it

disables the disk group and displays the following error:

VxVM vxconfigd ERROR V-5-1-123 Disk group group: Disabled by errors

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.

See “Backing up a disk group configuration” on page 56.

See “Restoring a disk group configuration” on page 57.

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,
