vxconfigbackup - back up disk group configuration


/etc/vx/bin/vxconfigbackup [-f] [-l directory] [[dgname ...] | [dgid ...]]


The vxconfigbackup utility can be used to back up the configuration information for one or more disk groups. Specify the disk groups either by name or by identifier (ID). If no disk groups are specified, all disk group configurations are backed up. To create a backup for a Flexible Storage Sharing (FSS) disk group, you must run the vxconfigbackup command on each of the cluster nodes that contribute storage to the FSS disk group.

For the complete procedure to back up the FSS disk group, see the Administrator’s Guide for your Veritas InfoScaleā„¢ product.


-f Forces a complete backup.
-l directory Specifies a directory other than the default where the backup configuration files are to be written.
Note: The default backup directory is /etc/vx/cbr/bk.


Back up the configuration of the mydg disk group to the directory /dgbackup/mydg:

vxconfigbackup -l /dgbackup/mydg mydg


  Default location of backup file for disk group information.
  Default location of backup file for disk attributes.
  Default location of backup file for binary configuration copy.
  Default location of backup file for configuration records in vxprint -m format.
  Default location of backup file for disk label information for each CDS formatted disk that has an SMI (Sun Microsystems, Inc.) label.


The vxconfigbackupd daemon automatically backs up a disk group’s new configuration to the default backup directory about an hour after the configuration is changed. The vxconfigbackup command is provided to back up the configuration manually at any other desired time.

The disk group configuration backup and restore utilities do not save any data in the public region. This includes file system or other application data that is configured within Veritas Volume Manager (VxVM) objects.
