Description Use this command to display the HA status of the management modules. The display includes the
following information:
• Local MM state: warm or cold, recovering or recovered
• Remote MM state: warm or cold, recovering or recovered, or not available
• High Availability (enabled or disabled)
• Heartbeat (up or down)
• Health of standby management module
• HA synchronization status
The health of the standby CP is defined as follows:
Healthy The standby management module is running and the background health
diagnostic has not detected any errors.
Failed The standby is running, but the background health diagnostic has
discovered a problem with the blade. Check the logs to determine the
appropriate action.
Unknown The standby management module’s health state is unknown because of
one of the following reasons: the standby CP does not exist, Heartbeat is
down, or the Health Monitor has detected a configuration file error.
The High Availability synchronization status is defined as follows:
HA State synchronized
The system is fully synchronized. If a failover becomes necessary, it is
non-disruptive.
HA State not in sync The system is unable to synchronize the two management modules. This
may be caused by one or more of the following conditions:
• A failover is in process but not completed
• The standby management module is faulty.
• A system error occurred.
If a failover becomes necessary while the management modules are not in sync, the standby
management module reboots, and the failover is disruptive.
