No idea which raid controller model you are dealing with.
Its a Perc 5/i if that helps.
Ah yes. Those. It Might Be Dead.
(A past gig had a lot of Dell servers, an annoying number of which were suffering from dead RAID controllers and/or remote consoles, while the IBM, HP, and Sun hardware generally just kept working.)
However, the various hardware RAID controllers I've had to deal with always had a BIOS screen (usually a pause during boot telling you hit some key combo to enter RAID config) and you need to get into that to tell it to forget the old setup and usefully configure (mirror, stripe, or JBOD) the drives it has now. This will also confirm it does actually see them. After that's done, it should present its virtual drive(s) to the OS.
Apparently the Perc 5/i can't do JBOD. The standard work around appears to be to create a 1 disk RAID0 on each drive and use those as the disks.
Well - - I would not have thought of that. As I wanted 4 discs on a Raid 10 and 2 on a Raid 1 I think I am happy with how things have worked out. Now if this system craters then I do know that the next purchase will be a little different. I like the processors in this box but the bios is a royal pita and some of the other decisions make by the system designers choices do leave something to be desired. Thanks for the help and information! Dee
