Better use the tsmscsi for the library and the native LTO drivers, (there
is certified driver on the ftp.software.ibm.com choose storage and look for
the drivers)

Make use you use at least tsm server 4.2.1.6 or higer since there was a
problem with data corruption and the LTO devices in 4.2.x

good luck

I wouldn't do this.  Use the native device drivers rather than the tsmscsi
driver for these drives.  You are probably ok for the driver, but since the
elements are switched, TSM is putting the tape in one drive and then
expecting to see it in  the other drive.  Thus the timeout.

Gill,

I will suggest you to do the following -

Your drive definition shows you are using \\.\tape0 device, which means you
are using windows driver for tape drive. You should install TSM device
driver from TSM installation CD if you have not already done so.

Then you need to disable your two drives and robotic arm in windows device
manager and reboot your server. After that start TSM utilities MMC and in
device information find out device name for your drive1 and drive 2. Then
redefine your drives using TSM device name. Delete your storage pool
LTOPOOL1 and device class LTOCLASS1. Define again LTOCLASS1 and don't
specify any format parameter this time. Define your storage pool again.

Ensure that your cartridge holder is installed properly in library and
library door is closed.

Can anybody out there help, I have a windows 2000 server currently running
TSM 4.2(going to be upgraded to 5.1). I have just connected up to it, our
3583 LTO library. I have defined the library and the drives in TSM using
the
following commands

DEFINE LIBRARY LTOLIB1 LIBTYPE=SCSI DEVCIE=LB6.0.3.2
DEFINE DRIVE LTOLIB1 DRV1 DEVICE=\\.\TAPE0 ELEMENT=256
DEFINE DRIVE LTOLIB1 DRV2 DEVICE=\\.\TAPE1 ELEMENT=257
DEFINE DEVCLASS LTOCLASS1 DEVTYPE=LTO FORMAT=DRIVE LIBRARY=LTOLIB1
DEFINE STGPOOL LTOPOOL1 LTOCLASS1 MAXSCRATCH=30

but when I go to label and checkin some tapes, the library picks the first
tape then loads it into one of the drives and then it times out..... with
the following error codes in TSM: ANR8304E, ANR8302E, ANR9999D, ANR8446I. I
hope that someone can shed some light on this for me.

Thanks
Dallas
