Moving failed RAID 6 ADG

[Tim Ko Impco Tech]

my remote site had a major crash including 2 drives faulted on a raid 6 (6 - 146G drives), p400 array card system.

I had them ship the drives and I was able to load 4 good drives on another p400 card, created a new array, assign a logical drive using ACU, and the system even detected previous raid 6 configuration. So far so good, I think?

My problem is I still can't see any data and the ACU has a status of (Background parity intialization is currently queued or in progress) for last 4 hours? I'm jsut wondering if I need to wait or am I SOL with the data on this RAID?

My windows 2008 server detects the drive as RAW data and wants to format, which obviously i can't do?

Thanks in advance for any advice.

hello,
your raid6 should handle 2 drives failure. Left it in peace for a while, recounting 2 drives from raid "could" be time consuming.

you are right about the 2 drives, but the new system does not recognize any logical drives, (1785-slot 1, drive array not configured).

also remember my server @ remote site also crashed, so i'm trying to revive my RAID using a similar hardware.

hmm, thats pretty bad. Your old server is completely smashed? Normally, smart array controller recognizes raid setting/status from drives. Is it is not ypour case, I am afraid it is time co contact hp support...

Something doesn't sound right. You shouldn't have had to create anything using two of the original existing drives or HBA. If you're using all new components then I don't understand what you're trying to do.

What did the system do when it detected a previous RAID 6? Did it rebuild on it's own or did you intervene?

If you lose both the configuration drives and the controller, then you'll have to create the volume and restore from backup.

Check and compare the System BIOS (yep on some version of the P400 it needs to be at a certain version), firmware, driver and ACU versions one old and new system.

Also, older P400 firmware had some issue with rebuilds under specific situations.

Run ADU and look for reasons why the array isn't rebuilding or post it here and maybe someone can help.

Rgds,
