The following techniques can be used to backup mirrored volumes by temporarily taking one of the mirrors offline and then reattaching the mirror to the volume once the backup has been run.

1. Disassociate one of the mirrors from the volume to be backed up:

vxplex dis

2. Create a new, temporary volume using the disassociated plex:

vxmake -g -U gen vol tempvol plex=

3. Start the new volume:

xvol start tempvol

4. Clean the new volume before mounting:

fsck -y /dev/vx/rdsk//tempvol

5. Mount the new volume and perform the backup

6. Unmount the new volume

7. Stop the new volume:

vxvol stop tempvol

8. Disassociate the plex from the new volume:

vxplex dis

9. Reattach the plex to the original volume:

xplex att

10. Delete the temporary volume:

vxedit rm tempvol

To display the current Veritas configuration, use the following command:

vxprint

To monitor the progress of tasks, use the following command:

vxtask -l list

To display information related to plexes, run the following command:

vxprint -lp
