As your system expands, you may need to add disk hardware.
This also means modifying the logical volume structure. Use the
following general procedure: Halt packages. Ensure that the OPS database is not active on either
node. Deactivate and mark as unshareable any shared volume
groups. Halt the cluster. Deactivate automatic cluster startup. Shutdown and power off system before installing
new hardware. Install the new disk hardware with connections on
all nodes. Reboot all nodes. On the configuration node, add the new physical
volumes to existing volume groups, or create new volume groups as
needed. Start up the cluster. Make the volume groups shareable, then import each
shareable volume group onto the other nodes in the cluster. Activate the volume groups in shared mode on all
nodes. Start up the OPS instances on all nodes. Activate automatic cluster startup.

worksheets (described in the "Planning" chapter)
so as to record the exact configuration you are using. | | | | |
