I'm getting something similar with a new FC2 install on a Dell Power 
Edge 750 server.

I have this working properly on an old clone running FC1, but it seems 
FC1 doesn't like the NICs that Dell put into the new server.

Tape drive is a Sony SDX-700C AIT3, and it's in a Breece-Hill 8 pack 
library, SCSI card is an Adaptec 29160. in FC2 I can do a cat 
/proc/scsi/scsi and it sees the SATA drive, the library and the AIT3.

Sony has a utility called "sonytape" however it DOES NOT recognize the 
drive. Neither does NetVault 7.1.

Ideas anyone?
