WE CURRENTLY HAVE A SERVER THAT HAS FOUR HARD DRIVES IN IT. THE SETUP IS THAT 2 ACT AS A MIRROR TO THE OTHER TWO. THE ISSUE IS THAT ONE OF THE HARD DRIVES KEEPS FAILING AND WOULD LIKE TO REPLACE WITH A NEW ONE. CAN THIS BE DONE WITHOUT AFFECTING THE MIRROR AND OR DATA.. EVERYTIME THE DRIVE FAILS I HAVE TO GO INTO THE BIOS AND REBUILD IT SO WOULD IT MATTER IF IT WERE A NEW DRIVE? OR DO WE HAVE TO FIRST BREAK THE MIRROR THEN SWAP THE BAD DRIVE OUT??
THANKS!!!

Hi escme16,

Normally you will just be able to put in a new drive and then rebuild the array. But if we know what raid controller you're using it will be much easier to know this for sure.

And please, don't use CAPS as it looks like shouting.

Greetings,

LucF

Assuming you mean this one:
http://www.lsilogic.com/products/ultra160_scsi_raid/4751010232a.html

It supports the rebuild, so you should be able to just replace the disk, if you have hot-swap bays, you don't even have to shut down the server.
