haShow
Displays control processor (CP) status.
Synopsis hashow
Description Use this command to display the control processor status. The display includes the following information:
• Local CP state (slot number and CP ID), warm or cold, recovering or recovered.
• Remote CP state (slot number and CP ID).
• High Availability (enabled or disabled).
• Heartbeat (up or down).
• Health of standby CP
• HA synchronization status
The health of the standby CP is defined as follows:
Healthy
The standby CP is running and the background health diagnostic has not detected any
errors.
Failed
The standby CP is running, but the background health diagnostic has discovered a problem
with the blade. Check the logs to determine the appropriate action. Failover is disabled until
the standby CP is repaired. Information about the failing device in the standby CP is
displayed.
Unknown
The standby CP 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 currently fully synchronized. If a failover becomes necessary, it is
nondisruptive.
HA State not in sync
The system is unable to synchronize the two CPs. This may be caused by one or more of
the following conditions:
• The haFailover command was issued. In this case the "HA State not in sync" state is
transitory.
• The standby CP is faulty.
• The haSyncStop command was issued.
• A system error occurred.
If a failover becomes necessary while the CPs are not in sync, the standby CP reboots, and
the failover is disruptive.
