attached to the original volume. The snapshot volume is removed. This
task resynchronizes the data in the volume so that the plexes are
consistent.
To merge a snapshot with its original volume, use the following
command:
# vxassist snapback
replica-volume
where
replica-volume
is the snapshot copy of the volume.
By default, the data in the original plex is used for the merged volume.
To use the data copy from the replica volume instead, use the following
command:
# vxassist -o resyncfromreplica snapback
replica-volume
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.
To dissociate a snapshot from its original volume, use the following
command:
# vxassist snapclear
replica-volume
where
replica-volume
is the snapshot copy of the volume.
Displaying Snapshot Volume Information
The vxassist snapprint command displays the associations between
the original volumes and their respective replicas (snapshot copies).
The syntax for the snapprint option is:
# vxassist snapprint [
volume-name]
The output from this command displays the following:
V NAME USETYPE LENGTH RP NAME VOLUME LENGTH
RRPLEXID
v vol fsgen 2048 rp vol-05 SNAP1-vol 3040 rp
vol-04
If a volume is speciļ¬ed it will display either output for that volume or an
error message if no FMR maps are enabled for that volume. Otherwise, it
will display information for all volumes in the disk group.
