PERC 5i - RAID 5 with 3 Disks shows 2 Disks missing?
I have a PE2900 with a PERC 5i, The first volume is a RAID 5 with three disks. This morning the PERC controller says that two of the disks (MAXTOR SAS 68GB 10K RPM) are missing.
Is that normal to lose two disks at the exact same time? Or could it be the controller that's going bad?
Is there anyway to test these drives without breaking the Virtual Disk? Or am I out of luck losing two out of three disks in an RAID 5?

Then on the VD MGMT screen, highlight the controller in the upper-left, F2, Foreign, Import.
It should move one from foreign to online and leave the other as failed ... leave things as is until you can confirm the OS boots and is ok, then you can rebuild the remaining disk.

In CTRL-R, go to the PD MGMT screen ... what is the status of each drive listed there?

It created a new virtual disk group with the two formally failed drives.
How do I get those into the first Virtual Disk Group?

Have any drives been removed or replaced ... or anything else we might need to know about?

Which disk ID's are we talking about here? 00-03? Which are which?

No… the disks haven’t been moved or changed… the volume failed at 4am in the morning.
Nobody was here and I'm the only person with the key to the server room.

So I couldn't wait for an answer... so with the new Virtual Disk group 2 having 2 disks out of 3, I set VD2 as the bootable drive and the OS booted. But slow.
So I would imagine if I don't run into any problems I should remove the last drive from VD0 and add it to VD2 and let it rebuild.

Sorry you couldn't wait ... I have to sleep sometime :)
Now that you are in the OS, make sure you do the rest of the work (clearing, rebuilding/assigning hot-spare, etc.) from the OS, using the OpenManage software.

Hello Flash, I'm in the exact same situation as this gentleman with a PE2950. 6 drives RAID 5 SAS same status two drives 0 and 4 show up as missing. I'm thrilled to see your suggestion fixed this for him but what did you end up doing as your main response doesn't show up anywhere in the message board. Please help sir. Thanks.

Did you try importing the foreign configuration as suggested?

Flash,
Did I fail to thank you? You really saved my rear end. I think I would have done something stupid like re-formatting the drives or something just as spectacularly idiotic.
Thank you.
