To resynchronize a snapshot with the primary database
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 command on the primary host to recover and restart a snapshot
volume:
# vxrecover -g volumedg -m snapvol
6
Use step 3 through step 5 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.
Updating a warm standby Sybase ASE 12.5 database
If you specified the for external dump clause when you quiesced the primary
database, and you started the replica database by specifying the -q option to the
dataserver command, you can use transaction logs to update the replica database.
