We lent our 24Tb storage system to a customer for achive reasons, and it's come back in a strange state. The customer says he did nothing but I suspect he tried to wipe his data.

I have a valid Raid6 partition on the 3Ware controller but Volume manager reports the 20.5Tb partition (Unit S0001) as Not Supported, 64 Bit. Everything else reports No system volume found.

Within Volume manager I cannot select the unit S001 so cannot do anything with it

So I don't mind about the data, nor the volumes that were set up previously as I can recreate these. How can I use my storage unit again?
