Hello John,
I do not see any logs attached but based off the two screenshots you have three drives in a leftover (possibly failed) state, with 7 slots possibly containing missing drives. There is also a global spare available but I cannot see information about the vdisk(s). While the firmware on the array is an older version, recovery of the vdisk might still be possible, especailly if the leftover drives belong to the failed vdisk. I don't see the failed controller on the screenshots provided, so I may not have the full picture.
If the customer is wanting data recovery, your best option is to get them into a support case. Trying to troubleshoot data recovery in a support forum is not the best path forward and without more data such as logs, I cannot tell if recovery is even an option for this customer.
Also, the firmware on the array has been inactive since September 2010. This customer likely needs to talk to their sales team and begin talks towards a new MSA2050 array.
Hope this helps your customer.
Cheers,
Shawn
