I'm trying to correctly use my FUJITSU M2513A MO drive with FreeBSD and get some SCSI errors when trying to unmount my tape : # umount /mnt (da1:ahc0:0:4:0): SCB 0x2 - timed out in command phase, SEQADDR == 0x154 (da1:ahc0:0:4:0): BDR message in message buffer (da1:ahc0:0:4:0): SCB 0x2 - timed out in command phase, SEQADDR == 0x154 (da1:ahc0:0:4:0): no longer in timeout, status = 34b ahc0: Issued Channel A Bus Reset. 1 SCBs aborted So here's my setup : Motherboard : Gigabyte GA-6BXDS with 2 SCSI integrated buses.
