I applied infrastructure and server FW updates to our Cisco UCS environment the other day. I used Auto Install.
For the Infrastructure Firmware update, I expected to lose half my SAN fibre paths and half my network paths during each one of the Fabric Interconnect reboots. I was pretty sure all hosts/blades (Windows Servers and ESXi Hosts) would ultimately stay up.
Well, all hosts stayed up except one ESXi host.
I have different Policies for Windows Servers and ESXi Hosts. Both ESXi Hosts use the same policies.
I have taken a look at the ESXi hosts themselves via the KVM just to see if something would be wrong there. Nothing.
I took a look in the vSphere vSwitch0 (Mangement/vMotion) of both hosts and still nothing inconsistent.
I made sure both ESXI servers were using the same Service Profiles/Policies. They are.
Although the same, I took a look at the VIF Paths, and Network tabs but I found no differences. I didn't expect to.
So if both use the same Service Profile Template and I have no Faults at all, where else should I look? Am I missing something here? Obviously I am.
Thanks
