15. On the OHP host, use the appropriate database commands to recover and start the
replica database for its decision support role.
When you want to resynchronize the snapshot volume’ s data with the primary database,
you can refresh the snapshot plexes from the original volume as described below:
1. On the OHP host, shut down the replica database, and use the following command to
unmount the snapshot volume:
# umount 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 import snapvoldg
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 volume is initially disabled following the join. Use the following
commands on the primary host to recover and restart the snapshot volume:
# vxrecover -g volumedg -m snapvol
# vxvol -g volumedg start snapvol
The contents of the snapshot volume are now ready to be refreshed.
You can then resume the procedure from step 6 on page 324. The snapshot volume can be
split from the disk group when synchronization is again complete.
