: Thanks for your reply, but, alas, it din't help.
Foo, it's something else then :-)
: My (current) setup is as follows :
: Sun SS4, Sol 2.5, HP1553A, as scsi id 5, Autoloader switch is set
: to 5 (1 on 2 off 3 on 4 off), The switches on the DAT drive itself
: are all ON, except 4, 7 and 8.
Hmm. You might like to try your switches at 11001100 and see if
that makes any difference -- it tweaks the scsi behaviour just
: Herre is the output from what you suggested :
: # cd /dev/rmt

: # mtx -d /dev/rmt/1 -I
: Hardware Error : No additional sense information
: With this showing on the console :
: Disconnected command timeout for Target 5.1
: Currently /kernel/drv/st.conf is empty - according to the info I found at
: http://www.dmo.hp.com/tape/c_sun.htm this should work ok.
Yikes! You should only _not_ enter anything into st.conf if you
have Solaris 1 (ie SunOS 4.1.x), in which case you would be
poking st_conf.c and rebuilding your kernel in any case...
You almost certainly won't get the compression device files to
work amongst other niceties unless you edit in the

The switch settings 11101100 or 11001100 are what should be okay.
"HP C1553A", "HP DDS 4mm autoloader", "HP-DAT2";
HP-DAT2 = 1, 0x34, 0, 0xd239, 4, 0x00, 0x13, 0x24, 0x3, 3;
Where X == 5 in your case.
A reconfigure boot after the above mods would be helpful.
In particular, the density codes given above make a big difference --
you get DC on/off by using device files, i.e if you use the above you'll
/dev/rmt/xl density == 0x00 (DC off!)
/dev/rmt/xm density == 0x13 (DDS1/DDS-DC)
/dev/rmt/xh density == 0x24 (DDS2)
/dev/rmt/x[uc] density == 0x3 (DC on)
The only other thing I can think of is that the timeout builtin isn't
particularly suited to your system, there is a version of mtx available
that hasn't got a hardwired timeout and will let you adb it so that
you can tune it to your system..
(not speaking for HP..)
