HP DAT40 Drive not working on K210

[Joe Holmes]

Hello -

I have a K210 server running 10.20. I am trying to
connect an HP DAT40e tape drive to the 28655A
SCSI SE interface. As the DAT40e is a LVD/SE
device, I am using an HP 50 to 68 pin SCSI cable.
Daisy chained to the tape drive is an external 40GB
LVD/SE disk.

The external disk works fine. The DAT40 does not.
The DAT40 responses to the ioscan inquiry. It is
CLAIMED and bound to the tape2 driver. However
when I access the DAT40 with a mt or diskinfo
command, I get "I/O Error".

I have stape/tape2 cuml patch PHKL_22855
installed. No help. I used the drive successfully
on my C160 station running 11.0. So the drive
is fine. Any ideas???

Thanks

Hi

first diskinfo command is nothing to do with DAT drives.

second have you got a tape in the DAT drive and are you specifying the correct h/w address when using mt

mt -f /dev/rmt/0m offl

this will use the tape at h/w address /dev/rmt/0m and take it off line , it will also complain if there is no tape in the drive.

try doing an ls of /dev/rmt to find out what devices drivers you have installed.

Joe,
Which kind of terminator do you use? You should force the system to SE with a SE terminator

Just a advice, don't put a tape device in the same bus of a disk device.

Joe,
Did you add the
tape2
scsi1
target
Driver to the kernel?
