The GDS (Global Disk Services) setup operations are described below.
"6.3.1 Setting Up System Disk Mirroring"
Set up system disk mirroring in both nodes, and then restart both nodes.
"6.3.2 Setting Up Shared Disks"
Set up the shared disk volumes.
Note
If you are using a shared disk unit, you must use GDS to manage that unit.
Be sure to configure GDS after initializing the cluster.
