mirroring hardware raids

[peterthorn]

I have two identical raids (united digital) connected via scsi to a xserver (10.5.5). Both of the raids are created as raid 5 and appears on the desktop as they should (meaning two disks, identical in size).
I would like to, with a software raid i Disk Utility, set them up as one should mirror the other, but Disk Utility gives me the error “Creating RAID set failed. Creating RAID set failed with the error. Could not add a RAID-disk to a RAID”.

I would have thought it would work, as both raid disks appear in Disk Utility as a single disk (with a scsi symbol on it) and not as a (software) raid….

So my question is, does anyone have any ideas on how to mirror the two raids?

Thanks,
Peter

They are partitioned as 1 partition each, both HFS + (I have tried both journaled and not). I unmount the drives in disk utility and drag the disks to the raid window (as you normally do), and it starts, but the the error appears. The partition on the first disk on the raid list is also lost, so it has started to do something (and it doesn’t seem to be malfunctioning disks, as it does it with the first disk on the list no matter what order I drag them to the window).

Unfortunately I can’t get the diskutil output right now, as I am away from the office.

Thanks,
Peter

While the Disk Utility RAID is nice to have, I find SoftRAID to be much easier to deal with and far more reliable. It’s easily worth the small price.
