[Veritas-vx] vxconfigrestore

[Asiye Yigit]

Hello All;

The following is in SF Troubleshooting guide.

As far as I understood, even VxVM objects (volumes, plex, subdisks,
etc.) are recreated?

Soi what about the data on them? We need to restore?

Regards,



If any of the disk headers are reinstalled, a saved copy of the disks'
attributes

is used to recreate their private and public regions. These disks are
also

assigned new disk IDs. The VxVM objects within the disk group are then

recreated using the backup configuration records for the disk group.
This

process also has the effect of creating new configuration copies in the
disk

group.

vxconfigrestore does, as you state, restore the disk group configuration
onto the disks private region. The content of the restoration should match
the most recently saved disk group configuration. The save is done
automatically when any VM object (v, pl, sd, etc., in the vxprint output) is
modified.

You might need to do recovery at the volume level in order to mount the file
system. The file system may need checking.

No restoration of data is necessary.

However (here it comes, the famous "it depends"), it depends on what you are
trying to do. If the reason you need to use vxconfigrestore is that you are
trying to recover public region content, then data restore might be
necessary. If it is a problem you suspect has been caused by VM a data
restore wouldn't be necessary.
