Hi, I have a Dell PowerEdge 2950 with 4 drives in a RAID-6 config on a PERC 6/I controller.  OMSA reports that Drive 2 is in a foreign state with predicted failure.  I have a replacement drive and was wondering what the correct procedure is to replace the drive.

1.  Do I just pull out the failed drive and install the new drive.  Clear the config if it reports as foreign and then assign as a hot spare

OR

2. Clear the foreign state of the failed drive first and then install the new drive and clear the config if it reports as foreign and then assign as a hot spare

Any suggestions appreciated

Then I would suggest pulling drive 2 and replacing it with the new drive. The array should sort it self out.

Should I leave the server up when replacing the drive.  Or shutdown, replace drive and power back on?

If the disks are in a RAID6 then you can leave server up.

This MUST be done hot, meaning with system powered on.

As dlethe said, it must be done "hot", regardless of RAID level. Since the drive is offline, there is nothing special you need to do - just pull the drive. If the drive was pred fail and still online, then you would need to force it offline before removing it.
