Hi
I have a problem between UCS FI and MDS switch port-channel. When MDS-A is powered down the port-channel fails but UCS blade vHBA does not detect the failure of the port-chanel on UCS-FI and leaves the vHBA online. However, if there is no port-channel between FI-->MDS it works fine.
UCS version
System version: 2.0(2q)
FI - Cisco UCS 6248 Series Fabric Interconnect ("O2 32X10GE/Modular Universal Platform Supervisor")
Software
BIOS: version 3.5.0
loader: version N/A
kickstart: version 5.0(3)N2(2.02q)
system: version 5.0(3)N2(2.02q)
power-seq: Module 1: version v1.0
Module 3: version v2.0
uC: version v1.2.0.1
SFP uC: Module 1: v1.0.0.0
MDS 9222i
Software
BIOS: version 1.0.19
loader: version N/A
kickstart: version 5.0(8)
system: version 5.0(8)
Here is the config from MDS switch
-------------------------------------------------------------------------------
Interface Vsan Admin Admin Status SFP Oper Oper Port
Mode Trunk Mode Speed Channel
Mode (Gbps)
-------------------------------------------------------------------------------
fc1/1 103 auto on trunking swl TF 4 10
fc1/2 103 auto on trunking swl TF 4 10
fc1/9 103 auto on trunking swl TF 4 10
fc1/10 103 auto on trunking swl TF 4 10
This is from FI.

fc1/31 103 NP on trunking swl TNP 4 103
fc1/32 103 NP on trunking swl TNP 4 103
Any thoughts on this?

Sultan,
This is a recently found issue and is fixed in UCSM 2.0.3a version .
which got duped to CSCtz21585
It happens only when following conditions are met
FI in End host mode
FC uplinks are configured for portchannel + trunking
Certain link event failures ( such abrupt power loss by upstream MDS switch )
