UCSM Failover

[Brian Hayes]

Isn't UCSM supposed to failover and become available again if there is a crach or reboot of the primary FI? I rebooted one of our UCS domains and when I booted the primary, it closes down UCSM. I never see a ping come back for the virtual UCSM ip until the FI that was rebooted starts pinging again.

Yes when setup correctly the UCSM VIP will come back up.  From my experience it takes about 45 seconds for arp to clear itself out and for the VIP to be pingable on the secondary node.

You can always login directly to the secondary via cli and check HA status.  It also takes a few seconds for the Secondary to become primary when your FI is rebooted.  Also a good practice to manually fail-over HA to the secondary if you are doing a planned reboot.
