Hi Kumar,

Before you can proceed with anything, just verify your /kernel/drv/st.conf.
Find your correct target and luns that appears on you /var/adm/messages.
Modify /kernel/drv/st.conf accordingly.  You can also modifying your
/kernel/drv/sg.conf in order to ignore the unneccessaries devices.

1.  Please Rebuild back you SG driver.  You can find the command to install
the SCSI-pass thru driver, /usr/openv/volmgr/driver/sg.install.
2.  Then, you have to rebuild back your /dev/rmt, rem_drv st.
3.  Remove the entire things under /dev/rmt/  directory.
4.  You ran, add_drv st.
5.  Please reboot your server.

The reason being, you drives are always down is, NetBackup wasn't able to
"talk" to you drive.  That's the most definite reason !

Best of luck !!
