question on replacing mirrored drives

By utken ·
Hi,

My Proliant ML 350 print server makes some grinding sound (not very laud) when it boots and once in a while when it's running. The fan seems to be working. I don't get any error in the Event Viewer though. I'm worried that it's coming from the SCSI drives but I'm not sure. There're 2 SCSI HDD (non-hot swap), mirrored. As they're already over 3 years old, I would like to replace them before they finally fail. OS is Windows 2000 server sp3.
What is the proper way to replace those mirrored hard drive? Do I need to break the mirror first before I move that files over? Currently the drives consist of OS and print drivers.
Any input is appreciated.

Being on the safe side use this way:

1. Backup
2. Shut down server
3. remove one of the disks and replace with a new one
4. after rebooting you will notice the broken mirror in disk management.
5. Remove the disk with the Red X from the mirror.
6. add the new inserted disk to the mirror and wait until the regeneration is complete.
7. shut down again and replace second disk.
repeat steps 4, 5 and 6.

Scan disks for errors and check eventlogs.

Before you go through the process in answer 1, check the fans by opening the case and THEN booting the computer so you see where the noise is coming from. I suspect a failing fan whcih will do this. It could also be the power supply fan. This is the bearings going bad.
