HBA sees the robot and the state is logged in. That means there is no issue with the HBA.

You aren’t going to see anything with sgscan unless cfgadm –al sees
the changer and the tape. I would work more with SUN to confirm there is
nothing wrong with the HBA…maybe try a diff HBA port.

All,
We have STK L180 tape library connected to a Solaris 10 master/media
server.Until 3 days back we were able to see tape drives and robots and
now the robot has disappeared. Initially when we were seeing the robot,
we were not able to configure it in netbackup. when we did a scan -changer on
that robot it used to report "0" drives and "0" slots
whereas the library has 6 drives and 84 slots. To fix that problem Symantec
suggested rebuilding the sg driver and told me to remove everything from /dev/rmt/*cbn
and /dev/sg directories. After doing that and rebooting the master with a
reconfiguration we lost the robot.
Everything is connected to McData switch and on the switch side I see all the
ports logging in without any error.However when i run cfgadm -al it shows this
for the robot wwn :
c3::500104f0005859c8
unavailable connected
configured failed
I have been working with Symantec and Sun and both are unable to identify the
problem.
I have tried resetting hba, resetting the robot, rebooting the complete library
etc but still sgscan and scan -changer does not show the robot.
I have 2 questions :
1) When the robot does not report on correct info in scan -changer command,
what can be the issue ?
2) What can we do to see the robot back ?
We are on NBU 6.0 MP6, with Solaris 10 on master, Emulex HBA, Mc Data Switch,
STK L180 tape library.
Thanks,
Dushyant Mehta
