This is... odd. Got a 6.8 box, a Dell R320 lspci tells me 01:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2008 [Falcon] (rev 03) so it *should* accept an SAS drive. I've got a Cheetah that's a few years old, and having pulled it out of another server (in the datecenter), I put it in this box to zero it out for reuse... and the box refuses to see the drive. *Nothing* in dmesg, *nothing* in /var/log/messages, and I tried echo "0" etc to get the SCSI buses to rescan. Anyone have any ideas? mark

You need to go into the RAID config (you should see an option to do this at boot) and configure a RAID with a single disk in a RAID0 configuration. Peter
