Cluster and Package Maintenance
Reviewing Cluster and Package Status
Chapter 7280
• Switching Enabled for a Node. Enabled means that the package can
switch to the referenced node. Disabled means that the package
cannot switch to the specified node until the node is enabled for the
package using the cmmodpkg command.
Every package is marked Enabled or Disabled for each node that is
either a primary or adoptive node for the package.
Service Status Services have only status, as follows:
• Up. The service is being monitored.
• Down. The service is not running. It may have halted or failed.
• Uninitialized. The service is included in the cluster configuration,
but it was not started with a run command in the control script.
• Unknown.
Network Status The network interfaces have only status, as follows:
• Up.
• Down.
• Unknown. We cannot determine whether the interface is up or down.
This can happen when the cluster is down. A standby interface has
this status.
Serial Line Status The serial line has only status, as follows:
• Up. Heartbeats are received over the serial line.
• Down. Heartbeat has not been received over the serial line within 2
times the NODE_TIMEOUT value.
• Recovering. A corrupt message was received on the serial line, and
the line is in the process of resynchronizing.
• Unknown. We cannot determine whether the serial line is up or down.
This can happen when the remote node is down.
Failover and Failback Policies Packages can be configured with one
of two values for the FAILOVER_POLICY parameter:
• CONFIGURED_NODE. The package fails over to the next node in the
node list in the package configuration file.
