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.
NOTES This command may not be supported on nonbladed systems.
Slot numbers for CP1 and CP0 vary depending on the hardware platform. On the Brocade DCX and DCX
8510-8, CP0 is in slot 6 and CP1 is in slot 7. On the Brocade DCX-4S, and DCX 8510-4, CP0 is in slot 4
and CP1 is in slot 5.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
