Cluster documentation.
5. If necessary, configure the quorum device on all nodes.
You cannot use a VCMDB device as the quorum device.
6. Initialize the root disk group on all nodes.
7. Initialize PowerPath devices on all nodes.
8. Start cluster services on the master node.
9. Designate/create shared disk groups on the master node.
10. Create logical volumes from the designated shared disks.
11. Create a logical host.
