I'm having a RAID issue and was hoping someone could clarify. At work, we're using a Sonnet Tempo SATA E4P to connect two Lacie 8TB RAID drives (4Big models) via ESATA. These two 8TB drives are mirrored via Software RAID.

We had some issues with the power supplies failing due to the person that originally set it up. Essentially, the power supplies were all wrapped up together and stuffed into a hot corner causing them to fail.

Since then, I've ordered new power supplies and placed them in better areas. The RAID finally mounts again, but I have this error in Disk Utilities

I've tried repairing the degraded RAID twice without any progress.. I guess the weird thing is the RAID Slice (E6243AE1-DCA9-4171-AD9B-68169384350B) is missing.. I'm not sure what that is or if it should even be there because we only have two drives connected.

Can i simply remove it from the RAID Set? I'm very concerned about losing data. Once I have this operational again, I can back this thing up and convince them to move over to a Hardware RAID system
