Raid 1 Hard Drive Failure


As I was restarting an HP ML370 G4 Windows 2003 Server std. Edition,  I noticed that Slot 1 from the hard drive cage had an amber light on.  The Riad Breakdown is as follows:

1.  Raid 1 to Slots 0-1.
2.  Raid 5 to slots 2-4.

The C: Drive consists of the mirror Raid array (Slots 0-1).
The D: Drive consists of the Raod-5 array (slots 2-4).

I believe the correct thing to do to fix this problem is:

1.  Get the same exact hard drive that is used in slot 1 (With the amber light flashing).

2.  While the Server is up and running hot swap the bad hard drive with the new hard drive.
     a.  I think it should take about 8 hours to replicate over.

Does that sound correct?

Technically as long as the drive is >= the capacity of the old one, then you are OK.   Best practice, however is same make/model/firmware revision, but if that means risking your data longer than necessary, best to either rebuild the RAID1 with a larger disk, or kick off a backup and then wait till the right one comes in.

How about the hot swap procedure?  Just take the bad hard drive out and then inser the good one?
