Veritas Volume Manager 5.1 SP1 Administrator"s Guide (5900-1506, April 2011)

The snapshot volume is initially disabled following the import. Use the
following commands on the primary host to recover and restart the snapshot
volume:
# vxrecover -g snapvoldg -m snapvol
# vxvol -g snapvoldg start snapvol
15
On the primary host, reattach the snapshot volume to its original volume
using the following command:
# vxsnap -g snapvoldg reattach snapvol source=vol \
sourcedg=volumedg
For example, to reattach the snapshot volumes svol1, svol2 and svol3:
# vxsnap -g sdg reattach svol1 \
source=vol1 sourcedg=dbasedg \
svol2 source=vol2 sourcedg=dbasedg \
svol3 source=vol3 sourcedg=dbasedg
You can use the vxsnap snapwait command to wait for synchronization of
the linked snapshot volume to complete:
# vxsnap -g volumedg snapwait volume mirvol=snapvol
Repeat step 5 through step 15 each time that you need to back up the volume.
Implementing decision support
This section describes a procedure for implementing off-host decision support
for a volume in a private disk group. The intention is to present an outline of how
to set up a replica database. It is beyond the scope of this guide to describe how
to configure a database to use this procedure.
