Displays control processor (CP) status.
Synopsis hashow
Description Use this command to display control processor status. The display 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 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. 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 is
displayed.
Unknown The standby CP health state is unknown 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. This may be caused by one
or more of the following conditions:
• A haFailover was issued. In this case the “HA State ‘not in sync’” state is
transitory.
• The standby CP is faulty.
• A 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.
Note This command may not be supported on non-bladed systems.
Operands none
Examples To display CP status, first on a healthy standby CP and then on a faulty standby CP:
switch:admin> hashow
Local CP (Slot 6, CP1): Active, Cold Recovered
Remote CP (Slot 5, CP0): Non-Redundant
