Not sure where to put this, so here goes… I’m in the process of rebuilding a G5 tower used as a server that was built by a predecessor. It boots off two 250GB drives that are RAIDed. I don’t have the password, so I attempted to change it using a Tiger install disk. Somehow booting off the DVD has broken the RAID set. I’m booting off a FW drive we use for diagnostics, and the drives show up in DiskUtility, but no RAID set up. if I do a ‘sudo diskutil checkRAID’ it says there’s no RAID set to check.

If I list the drives they show up fine, but neither one mounts. Output (edited) is:
[code] /dev/disk2
#: type name size identifier
0: Apple_partition_scheme *233.8 GB disk2
1: Apple_partition_map 31.5 KB disk2s1
2: Apple_Driver_OpenFirmware 512.0 KB disk2s2
3: Apple_Boot_RAID 233.8 GB disk2s3
/dev/disk4
#: type name size identifier
0: Apple_partition_scheme *233.8 GB disk4
1: Apple_partition_map 31.5 KB disk4s1
2: Apple_Driver_OpenFirmware 512.0 KB disk4s2
3: Apple_Boot_RAID 233.8 GB disk4s3[/code]

So the sanity check is this: If I run a repair mirror (sudo diskutil repairMirror disk2 disk4) will it wipe both drives or just rebuild the existing RAID setup? Is there any way to turn the separate RAID disks back into normal drives?
