I have a question that involves RAID but is more of an exchange question !

I have exchange server 2007 running on a Dell PE2850 with 6 Physical hard disks.

The PE2850 has hardware RAID in the following configuration.


Array Disk 0:0 & 0:1 c:\ drive RAID 1
Array Disk 0:2 & 0:3 D:\ drive Raid 0
Array Disk 0:4 & 0:5 E:\ drive Raid 0

Disk 0:2 is now failing for "Predictive Failure" and has failed the SMART Diags test.


My C:\ drive has windows server 2003
My D:\ drive has a live copy of exchange
My E:\ drive has a copy or exchange

so exchange must be replicating from D:\ to E:\ correct ?

My question(s) is,

can I just remove Array Disk 0:2 and replace with a new hard disk?
what happens with exchange ?

From what I understand, with RAID 0, one drive failure destroys the array ?

I'm worried that If I removed Array Disk 0:2 that exchange will fail.
Will exchange use the copy of its folder instead.

Previously Array Disk 0:0 failed and I replaced it with another disk no problem, but this was RAID 1 ( Mirroring )

Any help appritiated,

Ray..

What is the installation location of Exchange? D:\ or E:\ or C:\
If it's C drive then exchange will be intact, and if you have exchange database and log files on D and E drive then you have one choice. Restore the database from Backup for exchange.

can I just remove Array Disk 0:2 and replace with a new hard disk?
I hope those drives have Database and Log files only and not the binary files. If you are not running Mirroring then data will be lost.
what happens with exchange?
Explained above.

You need to provide more information on your environment. Mirroring is good.
