UCS HA doesnt show chassis

[debb.endara]

Hello, 

I want to upgrade Cisco UCS, so I run the command sh clu extended-state and I get the following output:

Cluster Id: 0xd3cdfc67281b11e2-0xbc97547feea856e4

Start time: Mon Sep 19 09:23:01 2016
Last election time: Mon Sep 19 09:24:24 2016

A: UP, PRIMARY
B: UP, SUBORDINATE

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

INTERNAL NETWORK INTERFACES:
eth1, UP
eth2, UP

HA READY
Detailed state of the device selected for HA storage:
Chassis 2, serial: FOX1739H3JZ, state: active
Chassis 3, serial: FOX1634H9Q8, state: active
Chassis 4, serial: FOX1735GW36, state: active

Seems like everything is alright, but in the list of device id does not show Chassis 1. Does some know why it could be?

Greetings.

You have nothing to worry about :)

UCSM only chooses 3 chassis or integrated rack servers to act as tie breakers (for split brain scenarios) in the event the L1/L2 connections go down.

You will only see a max of 3, which may change from time to time depending on IOM upgrades/reboots.

Thanks,

Kirk...
