From the Diag utility, I'd expect to see devices behind your SAS RAID controller that look something like:
- pdisk0 & pdisk1 - for the 2 physical disks.... in 2 slot locations ranging from P2-D1 thru P2-D12
- hdisk0, hdisk1, hdisk2, hdisk3, etc. - for any logical disks created by the SAS Disk Array Manager
- OR
- hdisk0 & hdisk1 - if the disks are configured as the default, regular JBOD
RAID isn't needed. If RAID is not configured, they are just a bunch of disks (JBOD). Look for the RAID Array Manager in your Diag screens.... it will show you if any RAID configuration is present (provided the drives are readable)...... or not.
I find it odd that you would have 2 faulty drives right out of the box.... unless your e-bay supplier knowingly sold it that way. But what do I know ?
I assume you've re-seated the drives & even tried another disk slot ?
