Hi Gurus,

I have L1000 Tape Library with one DLT Drive connected to Sun U 60
running Solaris 7 and Networker Legato 5.5.1. I Added one more DLT Drive
in L1000. I did following to add the Drive.

Physically connected DLT Drive in Drive 1 slot.

Went to LCD panel of L1000 -> operator tab -> Device -> Drive 1 -> SCSI
ID 4

Configuration is: Library -> SCSI ID 0

                         Tape Drive 0 -> SCSI ID 4 (Exisitng) -- >
/dev/rmt/1cbn

                         Tape Drive 1 -> SCSI ID 3 (New Added) -->
/dev/rmt/3cbn

After adding the new DLT Drive I powered OFF and ON L1000 and checked
from the LCD Panel and it did showed Second DLT Drive. Also Rebooted Sun
Box with -r option to probe new DLT Drive and it too detected second DLT
Drive (/dev/rmt/3)

I did follow the instructions given in the manual but problem is now
Jukebox doesn't work at all. It gives an I/O Error to any operations.

Here is error output:

-----------------------------

nsrjb: SYSTEM error, I/O error.

Mount/Unmount operation also gives an I/O Error.

Here is the output of inquire command:

----------------------------------------------------------

bash-2.05# ./changers

scsidev@3.0.0:Vendor <ATL>, Product <P1000 6220070>, Revision <1.*a>

Any Ideas?

We are not able to run the Production backup since new DLT is added.

Any Help will be greatly appreciated.

Thanks

Bhavesh
