Fabric Interconnect B - FEX not configured

gsebas941

Level 1

Hello community,

 

Summary of the problem: getting "FEX not configured" in FI Server port.

 

Topology

  • 2 FI in cluster mode (Fabric A(lead) Fabric B(subordinate)
  • 1 chassis

topologytopology

 

The objective is to have High availability of the Fabric Interconnects with one link from each Fabric Interconnect to each of the IOMs on the chassis. Port 1 in Fabric B is physically connected to port 1 in IOM 2 of the chassis, however, this link does not come up. When I look at the Properties window of Port 1 on Fabric B, it says:

 

Overall status: Link Up

Additional Information: FEX not configured

See screenshot below

Also look at global policies configuration just in case:

Thank you for your time, please let me know if I missed anything. I am fairly new at Cisco UCS.

 

EDIT: I also swapped the IOM 2 just in case the module was defective.

First, are L1 and L2 both physically connected between the FIs?

 

Secondly, Did you cannot to the console port of FI-B and configure that FI as part of the cluster?

 

You could perform an erase config on FI-B and re-configure as part of the cluster via console port.

Output of cluster state:

CIBUSA-FI-A# show cluster extended-state
Cluster Id: 0x44351fba530011e4-0x955a00059b702044

Start time: Wed Feb 14 11:28:49 2018
Last election time: Wed Feb 14 14:03:12 2018

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 NOT READY
No device connected to this Fabric Interconnect

L1 and L2 are connected and a cluster relationship is in place.

 

I configured the Fabric B to be part of the cluster via console port.

 

I will try to reconfigure Fabric B, but I want to understand why it is not working as of now.

 

Thank you for your response

Is this a new install? You may need to acknowledge the chassis in order for the FEX to be discovered as part of the cluster.

This is a new install, it has not seen production yet. When I acknowledge the chassis it performs the operation but the problem persists. I also swapped the IOM 2 just in case the module was defective.

Have you tried to decommission and re-commission the chassis? This will force UCSM to forget about and re-learn everything about that chassis.

 

If the problem persist, please provide the following outputs from each FI (a|b):

 

UCS#connect local a|b

UCS(local-mgmt)#show pmon state

UCS#connect nxos a|b

UCS(nxos)#show run int eth1/1

UCS(nxos)#show int eth1/1

UCS(nxos)#show int eth1/1 trans de

UCS(nxos)#show ver
