If you are not using the warm standby method, use the following isql command to
recover the database, roll back any uncommitted transactions to the time that the quiesce
command was issued, and put the database online:

Resynchronizing the Data with the Primary Host
When you want to resynchronize a snapshot with the primary database, follow these steps:
1. On the OHP host, shut down the replica database, and use the following command to unmount
each of the snapshot volumes:
# unmount mount_point
2. On the OHP host, use the following command to deport the snapshot volume’s disk group:
# vxdg deport snapvoldg
3. On the primary host, re-import the snapshot volume’s disk group using the following
command:
# vxdg [-s] import snapvoldg
Note Specify the -s option if you are reimporting the disk group to be rejoined with a shared
disk group in a cluster.
4. On the primary host, use the following command to rejoin the snapshot volume’s disk group
with the original volume’s disk group:
# vxdg join snapvoldg volumedg
5. The snapshot volumes are initially disabled following the join. Use the following commands
on the primary host to recover and restart a snapshot volume:
# vxrecover -g volumedg -m snapvol
# vxvol -g volumedg start snapvol
6. Use step 3 on page 54 through step 5 on page 55 to refresh the contents of the snapshot from
the original volume.
The snapshots are now ready to be re-used for backup or for other decision support applications.
