Refreshing an instant snapshot replaces it with another point-in-time copy of a parent volume. To refresh one or more snapshots and make them immediately available for use, use the following command:
vxsnap [-g diskgroup
If the source volume is not specified, the immediate parent of the snapshot is used. For full-sized instant snapshots, resynchronization is started by default. To disable resynchronization, specify the
syncing=no attribute. This attribute is not supported for space-optimized snapshots.
It is possible to refresh a volume from an unrelated volume provided that their sizes are compatible.
You can use the
syncwait command to wait for the synchronization of the snapshot volume to be completed, as shown here:
See "Controlling instant snapshot synchronization" on page 325.
