Changing Quorum Device in Oracle Parallel Server

Overview
==============================
The two database servers are cross-connected to two A-5000 disk arrays.

The quorum device is used when a server is starting up and it is not able
to contact the other server.
This can happen when both servers are down, and you are starting one up first,
or when the high-speed link is broken.

The quorum device MUST be on a disk that is visible from both servers.

The server reserves the quorum disk. It NEVER writes to the quorum disk.

When would you need to change the quorum device?
================================================
Examples:
You lose a disk array and both Oracle servers get shutdown.
The quorum device is on the broken disk array and you wish to start up
the OPS environment before you fix the array.

How to change the quorum device?
================================

On the machine you want to start up first
	# scconf kpdevcluster -q kpdevdb1 kpdevdb2
		Pick the SSA that is still operational
		Pick a disk on that SSA (any one will be fine)

On the machine you want to start up second
	# scconf kpdevcluster -q kpdevdb1 kpdevdb2
		Pick the same SSA as above
		Pick the same disk as above
