I want to expand an array of 4 disks in a DELL Poweredge 2300 which uses a PERC controller. Can I expand the array (by adding two more identcal disks) without having to wipe the current config and loose the data.

Yes, you can. You need to backup the current configuration and change the RAID config to use the new drives. This should allow the drives to auto-mirror the current data.

You should contact Dell for that, However as answer one pointed out with a backup you can do it anyhow.

To put it blunt, it is controller dependant. It depends on whether the controller can accomodate 6 drives. You first need to find out the maximum number of drives it can hold. Chances are your controller can handle it with no problems. All you have to do is power down the server, add the 2 drives to the chain, power it back up and start the scsi controller mgr. In the mgr, you should be able to easily add the two drives to the array, expanding it. Then you'll have to exit out, you'll probably have to reboot. Once you're up and running, go into the NT disk admin and add them to your existing partition.
