Building an HA Cluster Configuration
Configuring the Cluster
Chapter 5226
Both methods check the following:
• Network addresses and connections.
• Cluster lock connectivity (if you are configuring a lock disk).
• Validity of configuration parameters for the cluster and packages.
• 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 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 configured with a standby, two heartbeat LANs,
one heartbeat LAN and an RS232 connection, or one heartbeat
network with no local LAN switch, but with a primary 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.
• The network interface device files specified are valid LAN device
files.
• If a serial (RS-232) heartbeat is configured, there are no more than
two nodes in the cluster, and no more than one serial (RS232) port
connection per node.
• VOLUME_GROUP entries are not currently marked as cluster-aware.
• There is only one heartbeat subnet configured if you are using CVM
disk storage.
