Dushyant, you shouldn’t be seeing:
c3::500104f0005859c8
unavailable connected
configured failed
Until that is resolved you will not see things properly in
netbackup.
I run L700’s which are very similar, and I also run newer Emulex
cards and this is what I see from cfgadm –al:
c6::500104f00052ed2e med-changer
connected configured unknown
Ports that have tape drives plugged into them, used to need to
be configured as G ports rather than the default F port. I don’t think
that is the case for robots though. This robot has fiber control?
It is an older robot so I just want to make sure it doesn’t have a scsi bridge
or something like that.

Subject: [Veritas-bu] Robot disappeared from OS
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
