Step 9. On the primary host, deport the snapshot volume’s disk group using the
following command:
# vxdg deport snapvoldg
Step 10. On the OHP host where the replica database is to be set up, use the
following command to import the snapshot volume’s disk group:
# vxdg import snapvoldg
Step 11. The snapshot volume is initially disabled following the split. Use the
following commands on the OHP host to recover and restart the snapshot
volume:
# vxrecover -g snapvoldg -m snapvol
# vxvol -g snapvoldg start snapvol
Step 12. On the OHP host, check and mount the snapshot volume. The following
are sample commands for checking and mounting a file system:
# fsck -F vxfs /dev/vx/rdsk/snapvoldg/snapvol
# mount -F vxfs /dev/vx/dsk/snapvoldg/snapvol mount_point
Step 13. On the OHP host, use the appropriate database commands to recover
and start the replica database for its decision support role.
When you no longer need the replica database, or you want to
resynchronize its data with the primary database, you can reattach the
snapshot plexes with the original volume as described below:
Step 1. On the OHP host, shut down the replica database, and use the following
command to unmount the snapshot volume:
# umount mount_point
Step 2. On the OHP host, use the following command to deport the snapshot
volume’s disk group:
# vxdg deport snapvoldg
Step 3. On the primary host, re-import the snapshot volume’s disk group using
the following command:
# vxdg import snapvoldg
