Veritas Volume Manager 5.1 SP1 Troubleshooting Guide (5900-1507, April 2011)

Prepare the snapshot volume again for snapshot operations. Enter the

following command:

# vxsnap [-g diskgroup] prepare snapshot_volume

Clear the volume’s tutil0 field (if it is set). Enter the following command.

# vxmend [-g diskgroup] clear tutil0 original_volume

Recovering from the failure of vxsnap make for

break-off instant snapshots

If a vxsnap make operation fails during the creation of a third-mirror break-off

instant snapshot, the snapshot volume may go into the INSTSNAPTMP state.

VxVM can usually recover the snapshot volume without intervention. However,

in certain situations, this recovery may not succeed. If this happens, the snapshot

volume must be deleted.

To recover from the failure of the vxsnap make command for break-off instant

snapshots

◆

Type the following command:

# vxedit [-g diskgroup] rm snapshot_volume

Alternatively, the snapshot volume is removed automatically when the system

is next restarted.

Recovering from the failure of vxsnap make for

space-optimized instant snapshots

If a vxsnap make operation fails during the creation of a space-optimized instant

snapshot, the snapshot volume may go into the INSTSNAPTMP state. VxVM can

usually recover the snapshot volume without intervention. However, in certain

situations, this recovery may not succeed. If this happens, the snapshot volume

must be deleted.
