ML150 G2 with Raid 5 (w/4 drives)
Can I recreate a new array and not lose the data? I have a ML150 G2 with Raid 5 (w/4 drives) server. When booting it says the member drives are not part of the array - no operating system.
The drives show up in Disk Manager on an XP machine: Disk 1 - Healthy Disk 2 - Unallocated (not initialized) Disk 3 - Unallocated (not initialized) Disk 4 - Unallocated (not initialized)
Thank you!!! Desparate for help!!!

Answer Wiki:
When you take the existing drives and put them into a RAID 5 array it will wipe all the data from the drive which has data on it currently.

You have 1 of 4 drives in healthy state. In my opinion (please tell me if I am wrong) the raid 5 needs more than 1 drive to mantain the data (I know that a minimum of 3 disk is required to build a raid 5). Maybe you have lost your information and is more difficult to restore it than only to joining new drives to the raid.

you think you have RAID 5 but you only have JBOB. Are you using the HP RAID manager? Is this supposed to hardware RAID or software RAID? When you boot the server do you see the RAID being enumerated? You should be able to go look at the RAID config during post with a ctrl + s or ctrl + a, not sure which. I think you will have to backup the server and then configure the RAID, then restore to the new array.
