perc 6/i missing disk in array
Hi,
I have a problem with a perc 6/i controller, the disk in bay 1 is missing, the other 3 are found and ok.
It's set up as raid 10.
All disks are connected directly to the sas/raid controller (perc 6/i) without any backplane.
Replacing the missing disk still results in the status being missing.
However, in idrac 6 all 4 disks are found!
As a result of the missing disk, the array has become super slow.
Please note this is a production server, so rebuilding the array is not an option.
What are my options? Replace the controller or try to swap from port A to port B or is there a different way to "find" the missing disk?

Swedendedi,
Where are you looking at the drives? I assume the controller BIOS, if so what page are you on? The main screen or the Physical Disks page?

Ok, so if you hit CTRL-N from the main page to get to the Physical l Disks page, what does the drives show for Status? Does it show failed, missing, or just not there on that page?
If you remove and add replacement drive, what does it show up as under that page as well?

An engineer took a look at it and said this:
The only things that seems a bit promising is that when I plug in the old HDD the card tells me that "foreign configuration found" so it seems that the HDD is found outside of the RAID card but when I check in the RAID card config it's still missing.

Took a look at just now and the disk is found and the array is rebuilding. I can safely assume the rebuild will continue with the os fully booted? In other words, it doesn't have to stay in the raid bios till rebuild is complete?

That is correct, it will continue rebuilding after you exit the controller and boot to OS.

How long should the rebuild take? It's at 45% now, 4 disks 2TB each in raid 10.
It's working production so more data is being written to the drives all the time but 12 hours seems a bit long for just 45%....
see screenshot that I just took.

I have the exact situation where drive 3 is showing as "missing". But it has a green led on the front panel. In BIOS i cannot see any option to bring it online.

What system?
What controller?
What RAID config?
How many disks?
You have to be careful with terminology: Looking for an option to "bring it online" can be dangerous. If you had found an option to "force online", would you have tried it? It would have corrupted your array/data. Your disk, as was suggested in this thread for the original poster's problem, is most likely in a foreign state, which needs to be cleared and the disk set as a hot-spare to begin the rebuild. If your disk does not show up, even as foreign, then it is likely bad and needs to be replaced.2865

What system? Dell Power Edge 2900
What controller? Dell PERC 6/i Integrated RAID Controller
What RAID config? RAID 10
How many disks? 4 x 1 TB HDDDisk 2 Failure showed up so i replaced it with a brand new 1 TB Drive, hot swapped. Soon after that machine rebooted and showed foreign and i did Ctrl + R but this new drive shows as missing in BIOS under VD Mgmt. But it shows "Ready" when i ran DSET report.
You mentioned i have to clear it and set it as hot-spare. Can you please mention the steps?

Yes the controller bios (ctlr+r), however on all tabs (by pressing ctrl+N?) i get the missing disk or it simply displays 3 disks.
I can't reboot the machine now to check what it says, I can make some screenshots tomorrow if that helps.
