Cisco UCS Blades and vSphere DPM

jim_nickel

I followed this guide:

https://supportforums.cisco.com/docs/DOC-8582

And it worked, but I have 2 problems.

1) The blade being put into Standby starts back up immediately - almost like a reboot -

and doesn't stay in Standby mode

2) The Blade being put into Standby mode has Faults on all vFabric's etc because it is

"off"

Any suggestions?

Your issue is likely you have Power Management within the DRS  settings enabled.  If there's limited hosts, vCenter will immeidately  re-power up a host put into standby.  This is expected behavior for vCenter protecting the cluster.

Test - Disable DRS on your cluster, and then put a host into standby.  It should stay down indefinately.

Robert

Sorry...not the case.  We have 10 Blades and they are highly under utilized. Plus, DPM is in Manual mode right now.

I am testing and have not done a successful test...in other words, I have not been able to "Power On" because it won't stay down.

Shoot and a miss

I'd probably want to see the management logs from the host.  See if there's any IPMI calls coming from VC powering it back up.  Can you pull & attach a show tech for this blade (CIMC)?

Also need UCSM version, ESX build etc.

Thanks,

Robert

ESXi 5.0.0, 623860  - Nothing in the logs that shows VMware is sending another signal - only the Standby signal. In fact, it thinks it succesfully put it into Standby mode as the blade goes unresponsive for long enough.

BIOS: B230.2.0.1d.0.111620111513

Board Controller: B230100A

CIMC Controller: 2.0(1w)

One suspicion is that maybe UCS is interpreting the signal from ESXi as a reboot instead of a Standby.

If this is the case, then a firmware update is likely required.

I just tested this on my B200 M3 blades, works fine.

Let me test this on a B230 with that BIOS.

Provide the UCSM CIMC tech bundle, it will tell us if your suspicion is right or not.
