RAID 5 - Replaced Bad drive - now trouble
This is a old Dell r710 with the Perc6/i controller with eight 140GB SAS drives, running RAID5.
We had a drive (#5) fail. We replaced it and all seemed well - as the green light on the drive came on, the error cleared from the LCD and the machine kept running. About 30 minutes later, the server randomly rebooted.
Upon going to the controller it showed drive 5 as missing, but also showed drive 7 as missing even though it was green and didn't give an error on the LCD. We reseated drive 7 (and drive 5) but they both show to be missing on the CD Mgmt "tab" until Physical Disks. If I go to PD Mgmt, drive 7 shows as ready and drive shows as foreign.
I know that with Raid5, there is only tolerance for one failure, so I'm suspecting the virtual disk is gone, but... I wanted to check here in case there was something that I was missing.
Note: the ironic part is that we just installed a replacement server for this one earlier today, but hadn't migrated the virtual machines on the machine off yet.

Josh - thanks for the response. I just tried that and it said that the import failed with code 0xc
The drive that is "ready" (#7) was the last one to fail -- is there maybe a way to "force" that into service and see if the drive will at least boot?

Hi,
From the foreign view tab can you try to import the foreign configuration? It will probably put the foreign drive back online and you may be able to migrate your VMs.

What options do you have under PD mgmt for disk 7?

Try to clear the foreign config menu from the foreign view tab, which will put that drive into a ready state and then delete the virtual disk and recreate it without initializing. You should take a screenshot of the Virtual disk properties first so that stripe size and all of the other settings are the same. Once the new array is completed remove drive 5 and see if it will boot off of the remaining drives.
