VTL tape Drive I/O error

[sramb1]

Hello,

I've presented STK L180 VTL to linux server. Zoning has been done and I'm able to see the library on the linux server. I've installed lin_taped drivers and ITDT. In ITDT, when I scan for tape drives, it's showing the changer and drives. the device paths are below

changer --> /dev/sg0
drive 1 --> /dev/IBMtape0
drive 2 --> /dev/IBMtape1

When, I'm trying to run /opt/tivoli/tsm/devices/bin/autoconf, it's configuring only changer, but not the drives.

I've defines the library and it's path.

But, I'm not able to define paths for Drives. It's giving an I/O error.

tsm: SERVER1>DEFINE PATH server1 DRV01 srctype=server desttype=drive library=TSMLIB1 device=/dev/IBMtape0 online=yes autodetect=yes
ANR8420E DEFINE PATH: An I/O error occurred while accessing drive DRV01.
ANS8001I Return code 15.

Can someone please help me?

many thanks in advance

Try restarting the TSM instance and define the path after. Happened once to me and path definition reset after restarting the instance.

Also make sure that the device name is correct as Linux 'bounces' the devices around after server reboots. Avoid running the autoconfig - configure by 'hand'.
