Adding Disk Hardware
Chapter 392
Adding Disk Hardware
As your system expands, you may need to add disk hardware. This also
means modifying the logical volume structure. Use the following general
procedure:
1. Halt packages.
2. Ensure that the Oracle database is not active on either node.
3. Deactivate and mark as unshareable any shared volume groups.
4. Halt the cluster.
5. Deactivate automatic cluster startup.
6. Shutdown and power off system before installing new hardware.
7. Install the new disk hardware with connections on all nodes.
8. Reboot all nodes.
9. On the configuration node, add the new physical volumes to existing
volume groups, or create new volume groups as needed.
10. Start up the cluster.
11. Make the volume groups shareable, then import each shareable
volume group onto the other nodes in the cluster.
12. Activate the volume groups in shared mode on all nodes.
13. Start up the Oracle RAC instances on all nodes.
14. Activate automatic cluster startup.
NOTE As you add new disks to the system, update the planning worksheets
(described in Appendix A, “Blank Planning Worksheets,” so as to record
the exact configuration you are using.
