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

To snap back the snapshot volume on which you performed a snapclear, use

the following command (after using the vxdg move command to move the

snapshot plex back to the original disk group, if necessary):

# vxplex -f [-g diskgroup] snapback volume snapvol_plex

For the example output, the command would take this form:

# vxplex -f -g mydg snapback vol1 vol1-03

You cannot use the vxassist snapback command because the snapclear

operation removes the snapshot association information.

Recovering a version 20 DCO volume

To recover a version 20 DCO volume

Correct the problem that caused the I/O failure.

Use the vxsnap command to dissociate each full-sized instant snapshot volume

that is associated with the volume:

# vxsnap [-g diskgroup] dis snapvol

For the example output, the command would take this form:

# vxsnap -g mydg dis SNAP-vol1

Unprepare the volume using the following command:

# vxsnap [-g diskgroup] unprepare volume

For the example output, the command would take this form:

# vxsnap -g mydg unprepare vol1
