switch(standby)#
Step 3 Use the show system redundancy status command on the active supervisor to verify that the standby
supervisor did not complete the synchronization phase with the active supervisor.
switch# show system redundancy status
Redundancy mode
---------------
administrative: HA
operational: None
This supervisor (sup-1)
-----------------------
Redundancy state: Active
Supervisor state: Active
Internal state: Active with HA standby
Other supervisor (sup-2)
------------------------
Redundancy state: Standby
Supervisor state: HA standby
Internal state: HA synchronization in progress
The most likely reason for the synchronization to stall is that one of the software components on the
standby supervisor failed to synchronize its state with the active supervisor.
Step 4 Use the show system internal sysmgr gsyncstats command on the active supervisor to determine which
processes did not synchronize on the standby supervisor.
switch# show system internal sysmgr gsyncstats
Name Gsync done Gsync time(sec)
