Displays High Availability status information.
Synopsis hadump
Description Use this command to display information about the status of the High Availability (HA) feature on a switch or a
chassis. This command displays the following information:
• Time Stamp
• Local CP state (slot number and CP ID)
• Remote CP state (slot number and CP ID)
• Type of recovery (warm or cold)
• High Availability (enabled or disabled)
• Heartbeat (up or down)
• Health of standby CP
• HA synchronization status
• IP and Fibre Channel addresses configured for the switch or chassis.
• Additional internal HA state information, subject to change.
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 an appropriate course of 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.
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 control processors (CPs) because the standby
CP is faulty, an haSyncStop command was issued, or a system error occurred. If a failover
becomes necessary at this time, active CP reboots and the failover is disruptive.
