I have installed a Symbios Ultra2 32-bit PCI SCSI Adapter SYM8951U in my
FreeBSD 9.2 system. Attached to it is a Compaq StorageWorks MSL5026
tape library. I have never used this library before, but it was given
to me by someone who did use it. It worked at one time.
The system sees the changer, but not the drive. I've tried swapping the
SCSI cable and the LVD/SE terminator on the tape library ports. Same
result. After each cable retry, I run 'camcontrol rescan all'.
[dan@knew:/dev] $ ls *sa* *ch*
ls: *sa*: No such file or directory
ch0
[dan@knew:/dev] $
Any ideas? Suggestions? Card settings?
I conclude the cable is OK, given that I can get a list of the tapes in
the library.
The front panel of the library sees the tape drive. It has a SCSI ID
assigned.
$ sudo camcontrol amcontrol devlist
<COMPAQ MSL5000 Series 0520> at scbus7 target 3 lun 0 (pass10,ch0)
(NOTE: I have removed the SATA drives from the camcontrol output)
From dmesg, I see:

I can get a list of the tapes:
