Scsi target mode with qlogic 2312 card help

Fri Jun 25 13:49:53 UTC 2010

I managed to get the scsi target mode running by changing the 
isp_freebsd.c driver code to explicity put the bus in target mode when 
it loads. Earlier it used to "defer putting the bus in target mode".

The initiator reports "scsi scan: INQUIRY result too short (5), using 
36" . Does anyone have pointers on this ? Thanks.

Now , my scsi_target code when run on 0:0:0 shows :

scsi_target: sending ccb (0x332)
scsi_target: sending ccb (0x334)
....
....
scsi_target: sending ccb (0x332)

scsi_target: INQUIRY from 1: 12 20 0 0 24 0
scsi_target: sending ccb (0x933)

While the Linux initiator shows :
