Who Me Too'd this topic

Hello! We have 2 x UCS-FI-6248UP + 1 x Cisco UCS 5108 Chassis (7 Servers) with 2 x Nexus 5548UP Switches with L3 Modules (Data Ceter Routet Access Scheme).

In UCS Manager I see FI A with state "inapplicable" and Fi B is currently "primary".

Using CLI (connect local-mgmt A context) I can see:

NSX6248UP1-A(local-mgmt)# show cluster extended-state
Cluster Id: 0x5a479a88bbd711e2-0xbab0002a6a07b044

B: UP, PRIMARY

A: memb state UP, lead state INAPPLICABLE, mgmt services state: DOWN
B: memb state UP, lead state PRIMARY, mgmt services state: UP
   heartbeat state PRIMARY_OK

And there is message "ERROR: MGMT partition has unrecoverable error" during boot.

Boot time error

Can not open TAC without service subscription.

Thanks a lot for any help.
