Verifying GAB

Verify the GAB operation using the gabconfig -a command. This command returns the GAB port membership information.

The ports indicate the following:

Port a	Nodes have GAB communication gen a36e0003 is a randomly generated number membership 01 indicates that nodes 0 and 1 are connected
Port h	VCS is started gen fd570002 is a randomly generated number membership 01 indicates that nodes 0 and 1 are both running VCS

For more information on GAB, refer to the Veritas Cluster Server User's Guide.
