354 Administering volume snapshots

Creating traditional third-mirror break-off snapshots

2 Use the vxassist mirror command to create mirrors of the existing

snapshot volume and its DCO volume:

# vxassist -g diskgroup mirror snapshot

# vxassist -g diskgroup mirror $DCOVOL

Note: The new plex in the DCO volume is required for use with the new data

plex in the snapshot.

3 Use the

vxprint command to find out the name of the additional snapshot

plex:

# vxprint -g diskgroup snapshot

4 Use the vxprint command to find out the record ID of the additional DCO

plex:

# vxprint -g diskgroup -F%rid $DCOVOL

5 Use the vxedit command to set the dco_plex_rid field of the new data

plex to the name of the new DCO plex:

# vxedit -g diskgroup set dco_plex_rid=dco_plex_rid new_plex

The new data plex is now ready to be used to perform a snapback operation.

Dissociating a snapshot volume

The link between a snapshot and its original volume can be permanently broken

so that the snapshot volume becomes an independent volume. Use the following

command to dissociate the snapshot volume, snapshot:

# vxassist snapclear snapshot
