I don't know if it would give you a non-zero return.  You man have to =
look for the mode sense text itself.  If you have a non-production =
environment where you can test this you can see the exact text.

I'll see if I can generate something for you.

=20
Thank you David. tpconfig gives some information about the robot, but =
not whether it is UP|DOWN.
(It does give that information about the drives through).
=20
tldtest looks interesting though. While looking for a description of =
this, I also came across "robtest",
which seems to be an interactive front-end to tldtest. Using this gave =
me the right pathname to feed
to tldtest. (which is also looks to be somewhat interactive).
=20
For a fairly elementary health-check that I could call from a cron =
script,
looks like I can pipe what appears to be a fairly harmless sub-command =
like "mode" to tldtest, and test the exit code, e.g.:
=20
# echo "mode\nquit"| /usr/openv/volmgr/bin/tldtest -r /dev/sg/c1t0l0
Opening /dev/sg/c1t0l0
Enter tld commands (? returns help information)
First transport addr =3D 0, Number transport elements =3D 1
First storage addr =3D 31, Number storage elements =3D 20
First mailslot addr =3D 20, Number mailslot elements =3D 0
First drive addr =3D 1, Number drive elements =3D 2
MODE_SENSE complete
# echo $?
0
#
=20
(Assuming it would give a non-zero exit code if it was in trouble).

        Not that I'm aware of with vmoprcmd.  what I have done in the past is =
use tldtest -r <robotic path>, if it returns a mode sense to standard =
out, I know (almost for certain) I can't communicate with robotic =
control.

        I'm not sure if it lists whether or not the robot is "UP" or not there.

                We are running with a Sun Storedge L20 robot with HP Ultrium1 
LTO =
drives.=20
                Occasionally we will have a problem with the robotics requiring 
manual =

                intervention,=20
                typically requiring us to run an online test ("calibrate 
library") =
which=20
                usually sorts things=20
                out.=20
                I can see from /var/adm/messages that the robot has gone into a 
DOWN =
state,=20
                and=20
                then when the test has run, it goes back into the UP state.=20
                However, the log is only providing history, and I'd like to be 
able to =

                interrogate its status=20
                (from a script) in real time.=20
                I was wondering if there was a command around, similar to 
vmoprcmd =
(which=20
                reports=20
                on the drive status), which might tell me?=20
