Thanks to George Drew, Donaldson Mark, Marianne Van De Berg and those who
replied.

I found out that somehow the new tape drive entries is not created in
/etc/devlink.tab, so I manually create it and resolved the problem. Thanks
again for dropping hints

Cheers...
Robert

Robert,

The sg driver is by default configured to only build devices on luns 0
& 1. Run the following:

/etc/init.d/netbackup stop
cd /usr/openv/volmgr/bin/driver
../sg.build all -mt 15 -ml 4
rem_drv sg
rm -f /dev/sg/* /kernel/drv/sg.conf
./sg.install

Verify that all devices are visible using sgscan. If so,
/etc/init.d/netbackup start. If not, open a support case.

George
