Displays control processor (CP) status.
Synopsis hashow
Description Use this command to display control processor status, which includes:
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 (healthy, failed or unknown), defined as follows:
HealthyThe standby CP is running and the background health diagnostic has not detected any
errors.
FailedThe standby CP is running, but the background health diagnostic has discovered a problem
with the blade. The logs should be checked to determine the appropriate repair action. Failover is
disabled until the standby CP is repaired. Information about the failing device in the standby CP will
be displayed.
UnknownThe standby CP health state is unknown due because the standby CP does not exist,
heartbeat is down, or Health Monitor detects a configuration file error.
HA synchronization status:
“HA State synchronized”
The system is currently fully synchronized. If a failover became necessary, it
would be nondisruptive.
HA State “not in sync”
The system is unable to synchronize the two CPs because the standby CP is
faulty, a haSyncStop command was issued, or a system error occurred. If a
failover became necessary, at this time, the standby CP reboots, and the
failover is disruptive.
This command might not be supported on non-bladed systems.
The execution of this command is subject to Admin Domain restrictions that may be in place.
