Re: Power subsystem shows degraded status
Is the ROM, iLO and Power Management Controller firmware up-to-date for any Proliant blades in the enclosure?
Have you tried re-seating both OAs and the sleeve that they sit in?
good luck

Re: Power subsystem shows degraded status
It seems to be a reporting issue.
The ILO is responsible to provide blade power information and OA is responsible to gather power information from blades, power supplies, interconnects etc. and then allocate power.
Please verify the compatibility of all the firmwares

This should resolve the issue

Re: Power subsystem shows degraded status
OA - 2.60 Aug 31 2009
ROM - l24 01/14/2010
iLO - 1.81 Jan 15 2010
Power Mgt Controller - 3.4
VC - 2.32
I have confirmed that the power supplies are NOT subject to the "idenitfy and replace" problem.
The only difference between the two enclosures is the fact that one of the blades in the enclosure exibiting this behavior has Windows 2008 OS loaded. All the others are still "bare metal".
Still searching for a solution...

Re: Power subsystem shows degraded status
Is there a power profile in place via the OS that might be causing the discrepency?

Re: Power subsystem shows degraded status
Sorry for reviving this thread, but I'm now seeing the exact same issue. I'm on FW 3.56. I've tried reseating the OAs and replacing all the PSUs. No change.
Did you ever find a solution to this issue?

Re: Power subsystem shows degraded status
I think the actual fix for this problem was a new firmware update. v3.00 fixed a few power problems, but I don't believe all of them were documented in the release notes. But I think the one that was addressed was this:
- Fixed an issue where the "power capacity" values in "enclosure power summary" and "show power" may not match
Anyways, I'm actually seeing this problem as well on my chassis that I've upgraded to 3.56. I wonder if the bug got reintroduced? One of the other problems with v2.60 was erronous fan failures:
And I'm battling the same issue in 3.56 as well:
Might be worth a call to HP to see if that's really the case...

Re: Power subsystem shows degraded status
I have several enclosures on 3.56, but only 1 that suffer from this Power degraded issue.
All PSUs present output just show their maximum capable output. I have not done actual measuring on our PDUs, but I sure don't hope that they are actually pulling max power from the PDUs...
