Verifying GAB
Verify the GAB operation using the gabconfig -a command. This command
returns the GAB port membership information.
The ports indicate the following:
■ Nodes have GAB communication
■ gen a36e0003 is a randomly generated number
■ membership 01 indicates that nodes 0 and 1 are connected
Port a
■ VCS is started
■ gen fd570002 is a randomly generated number
■ membership 01 indicates that nodes 0 and 1 are both running VCS
Port h
For more information on GAB, refer to the Veritas Cluster Server User's Guide.
