robtest fails and the Drive are not detected and /dev/rmt is empty on the host side

Hi,

Netbackup version = 6.5
Netbackup server host = solaris 10.

My netbackup server was working fine with the ndmp configuration.

I have reconfigured my netbackup server 6.5  from ndmp to simple host to libraray.

I removed the iscsi cable from the filer to the libarary and
connected my scsi cable from the backupserver to the library.


i have deleted the previus enteries by using the /usr/volmgr...../tpconfig -delete.


Now when i am trying to add my drive and tape library again it throws me an error that ur drive is disabled.

I have followed the steps in the drive configuration guide.

1)  rm -rf /dev/rmt/*
2) st.install
3) reboot -- -r
4) changing the /kernel/drv/st.conf file
5) st.build to regenerate the st.conf file

but my /usr/openv/volmgr/robtest is failing

my /dev/rmt/ directory is empty
its not generating any nymber like 4cbn or 7 cbn even after running the scripts st.build and


Long Story Short

Its not recognizing my scsi driver for solaris (done the passthru driver thing).
Its not recognizing my drive





Thanx in advance
