BL20p G3 & Power Enclosure

[Oleg Koroz]

Is your Configuration with local UPS?

Confused with: All connecting on one phase?

However, probably it would be less related unless you have random shutdown or inadequate power messages.

Hi Oleg,

All servers an the two SANs are configured with a local UPS

> Confused with: All connecting on one phase?
Yes, correct, all units are using the same phase, they are all connecting to the same UPS.

Do I have any logs where I can find these messages?
We had the problem that one server shuts down without any reason!
We don't have any messages coming from the UPS.

14 per 1 Phase Power enclosure if you have two you double numbers

Where to look for Power Errors: in IML from ILO

Cable length: from Power Enclosure about 10ft A and B side. No documentation I looked all over.

I'm still thinking error that you have - Loss Of Chassis Connectivity - caused by Conflicting Management module from Blade Enclosure or One of Backplane Boards that seat insight of Power enclosure.

This error may occur some time if you have replaced the management modules.

Check with the management module connected to the enclosure sl.no. 800FJTK852 thru serial console.

For serial console testing check with Blade system user guide.

Remove all the interlinking UTP cables.
Check the enclosure serial no. in the console page.
Check in the management module's console, about enclosure serial no.
Check all the modules like this
Then connect the linking UTP cable.

Your error will get resolved.

@kvelayutham

the errors occurs befor replacing the management modules.
All Cables have been replaced as well.

We have checked a lot of Logs an send them to the Case at HP support. But from my point of view they don't know where to search.
They try to solve the problem thru firmwareupdate. but we had done several firmwareupdates yet.

Any progress on this. We have the same issue.

Hi mjcb2000,

we have a solution in this case :-))

We had a bug in the power-supplies.
The company building the power-line mixed up the phase in the cables.
We had a check of the hole power-system and as an result the company had to fix it. After that we did not had any problems yet.

Hope it stys that way.

I will give a detailed discription of the problem if you want.

Thx Thomas

Thanks Thomas. I never thought of getting that checked.

If it wouldn't be too much of an issue, could you provide me with the details so that I can pass them off to my electritian.
