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 files record disk group configuration information:

/etc/vx/cbr/bk/diskgroup.dgid/dgid.dginfo 

Disk group information. 

/etc/vx/cbr/bk/diskgroup.dgid/dgid .diskinfo 

Disk attributes. 

/etc/vx/cbr/bk/diskgroup.dgid/dgid .binconfig 

Binary configuration copy. 

/etc/vx/cbr/bk/diskgroup.dgid/dgid.cfgrec 

Configuration records in vxprint -m format. 

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.

Warning: 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 configuration

  1. Type the following command:

    # /etc/vx/bin/vxconfigbackup diskgroup

    To back up all disk groups, use this version of the command:

    # /etc/vx/bin/vxconfigbackup

    See the vxconfigbackup(1M) manual page.
