UCS 460 M2 - No SNMP access, no WEB login.

[david_carvalho]

Hello.

I have 2 UCS 460 M2 servers running

BIOS C460.1.5.4b.0 (Build Date: 03/08/2015)

CIMC 1.5(8a)

Suddenly, I can't login to one of them via Web browser, but the login page loads.  My zabbix can not also access SNMP information. If I start the server, the guest OS loads fine. Right now, I've unplugged all 4 power cables and I'm letting it sit for an hour or so.

Any idea of what happened here?

Thanks and regards.

Ok, so I left the server turned off over night, but I still had the same problem.

A while ago I disconnected the power cables for about an hour, plugged them in again and it is working. I was checking my UPS logs and it seems there was a power surge about the time this happened. Strangely, the affected server currently is idle and the other, which has some VMs running, was fine all the time.

Weird...

but solved.

You might want to bump up your UCS firmware, which includes the CIMC, with the HUU utility.

There was a memleak bug that causes that very symptom 

Memory Leak Issue Fix

Symptom Unable to access CIMC using SSH or HTTP. However, pinging CIMC is successful.

Workaround AC power cycle the server.(CSCun88303)

Symptom Server stops responding to XML queries due to a leak in the xapiserver process.

Thanks for the reply. I've downloaded the latest available (1.5.9), just waiting for a slower day to install it. Thanks!
