Verifying the Cluster Configuration
If you have edited an ASCII cluster configuration file, use the following
command to verify the content of the file:
# cmcheckconf -v -C $SGCONF/clust1.config
This command checks the following:
• Network addresses and connections.
• Quorum server connection.
• All lock LUN device names on all nodes refer to the same physical
disk area.
• One and only one lock LUN device is specified per node.
• A quorum server or lock LUN is configured, but not both.
• Uniqueness of names.
• Existence and permission of scripts specified in the command line.
• If all nodes specified are in the same heartbeat subnet.
• If you specify the wrong configuration filename.
• If all nodes can be accessed.
• No more than one CLUSTER_NAME, HEARTBEAT_INTERVAL, and
AUTO_START_TIMEOUT are specified.
• The value for package run and halt script timeouts is less than 4294
seconds.
•The value for HEARTBEAT_INTERVAL is at least one second.
•The value for NODE_TIMEOUT is at least twice the value of
HEARTBEAT_INTERVAL.
•The value for AUTO_START_TIMEOUT variables is >=0.
• Heartbeat network minimum requirement. The cluster must have
one heartbeat LAN that is configured as a link aggregate of at least
two interfaces.
• At least one NODE_NAME is specified.
• Each node is connected to each heartbeat network.
• All heartbeat networks are of the same type of LAN.
