Well, I've tried the 'sst' driver and it works only slightly better than
the 'sgen' driver. With the 'sst' driver I can send as many 'mtx inquiry'
commands as I like and they all work.
Also, the 'mtx inventory' command produces a response from the robotics
(the gripper arm moves out and in, but nothing else happens).
However, all other commands produce SCSI errors.
For example, 'mtx -f /dev/rsst5 first' produces this output:
# mtx -f /dev/rsst5 first
mtx: No such device or address
mtx: Request Sense: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
mtx: READ ELEMENT STATUS Command Failed
and this error message is logged from the kernel:

I don't know what this means, but obviously something is producing
incorrect results. Any ideas on what I can look at?
With other people reporting success using an ADIC-1200 autochanger with
the 'sg' driver in Linux, I'm surprised the 'sgen' and 'sst' drivers under
SunOS 5.8 are giving so many hassles...
Anyway, has anyone done much testing with the 'sst' driver in SunOS
5.8? It seems the bulk of people tend to use Linux or Windows so I guess
Solaris testing is not the primary focus of the Amanda development group.

Craig.
