SA 6400, changing failed disk with correct spare but different GPN causes other disks to fail

SA 6400, changing failed disk with correct spare but different GPN causes other disks to fail

In our Proliant ML 570 G2 with Smart Array 6400
we had a failed disk.

Changing the failed disk with the correct spare sent by hp support caused other disks to fail as well.

We removed all the new failed disks and inserted them one by one again. They appeared back working but the new inserted disk appeared failed.

After various tries (firmware upgrade, changing order of insertion of failed disks), we never managed to have the new disk to work together with the old ones.

We asked another new disk to hp support with same result.

It seems that our old disks with GPN 271837-004
cannot stay in the same array with the new ones
with GPN 404670-003. Either the new one or the old ones becomes failed when mixed on the same array.

Anyone had a similar issue?

All our 12 drives are configured whit a big logical drive RAID 1+0.

Diego.

Re: SA 6400, changing failed disk with correct spare but different GPN causes other disks to fail

Solved.

I'll tell you how, if anyone is interested.

After various tries and tests done by hp support, the issue has been solved changing both the back panel and the Smart Array controller.

In my opinion the culprit was just the first one.

The second one has been changed just because we have been deceived by the fact that pre-failing disks are shown with the blinkink red led only when the logical drive is consistent.

When another drive is missing or failed (steady red led) all the pre-failing drives becomes green. But they are back blinking red when the logical drive is rebuilt.

Is it a feature or a bug? :-)
