EVA4000 disk enclosure PSU failure

Vincent Farrugia — Mon, 08 Feb 2010 07:20:35 GMT

Good morning,

We have a customer who has a problem with his EVA. A PSU failure on a disk enclosure is failed intermittently and then it comes online again after a few minutes.

I will have to go to replace the PSU today but I don't know which one is failing :-)

The customer has 4 disk enclosures (2C4D)...

Attached please find the log file. I could decipher which disk enclosure is giving problems from it (disk enclosure 1) but I do not know which PSU.

Any help will be greatly appreciated with points :-)

Vince

It's not going to be clear from that.. the alarm code is for enclosure 2, not 1:

** START UNION: ( alarm_error_code - Alarm code ) **
value - As longword: 33686339 [0x02020343]

That decodes to:

ec - Error code: 3 [0x03]
en - Element number: 2 [0x02]
et - Element type code: 2 [0x02]

"Pwr Supply load balance error; replace the power supply now". On enclosure 2.

Can you export the events with "get log file" and attach them compressed here?

Much better this way, we have:

A drive enclosure power supply component has failed. Enclosure: 1.; Affected power supply: 2.;

Power supply 2 is the left one, looking at the enclosure from behind.

By the way, firmware 6000 is out of support since December 31, 2007. You should plan an update to 6220.

That is great! Thanks for everything.

Points assigned accordingly.

Hopefully tonight everything will go fine :-)

Hello again, I have searched in the service manual that PSU 2 is on the right looking from behind, not on the left.

Can you confirm that I have to replace PSU 2 on the right or on the left?

Thanks,
Vince

It is the other left side ;-)

I've looked into the HW config guide and the PS/blower replacement guide from 2005/2006 and both agree that PS2 is on the right side when looking at he enclosure's rear.

Sheesh, you're right, PS1 is left and PS2 is right. I had in my mind that the order was the opposite of the new M6412 enclosures, and the same as I/O modules (A is right, B is left), but no, power supplies are reversed...

But on that enclosure PS2 is on the right side, too - (all objects on it count from top-to-bottom, then left-to-right if you directly look at them).
