Need to format/erase SCSI disks that were part of a raid array. Non-Standard Hardware.

Junior Admin level skills.
We were generously given a number of servers, labeled as Dell but obviously not standard boxes. When I am able to install an OS, they come up as Dell BlackfordESB2 (instead of 1950, etc). Most of these boxes contain disk that were part of a different raid so I can't use the built in utility to configure.  I have booted a number of different Dell configuration disks but when I launch the config utility it always come up as "unsupported system". I am desperate for a way to erase these disks so I can then reconfigure and deploy these systems. I can boot these systems using an external USB DVD drive but is there a utility I could use to erase these disks?

Can't you use the inbuilt RAID utility with just one disk plugged in? Short of that you will need a non-RAID SCSI HBA although there is also the possibility of hot-plugging them into a running system and using the controller softwar on them that way. They may not have Dell PERCs in though, so see whether you can find a controller inside them.
Buy a used adaptec SCSI controller on ebay. Any model will do as long as you can plug it in & get the cabling right.  The Adaptec firmware POST has option to do a low-level format so it can destroy old metadata.  

Make SURE the controller  is JBOD, not RAID, so a 29x160, or 29x320, 29xx family will do the trick.

You should also let the BIOS do the media verification.  Might as well let a HDD fail diagnostics now rather than let it die shortly after you install it into production.
