Ira,
When you type "dmesg" after loading the tape driver, you will find
something like:
Jun 11 10:13:57 gfree06 kernel: TCHAR:<3>Tape gets major XX for char device
Jun 11 10:13:57 gfree06 kernel: TBLOCK:<3> tape gets major YY for block
device
The tape driver allocates major numbers dynamically.
In order to access your tape devices you have to create device nodes:
First device:
mknod /dev/ntibm0 c XX 0 (where XX is the number form the dmesg output)
mknod /dev/rtibm0 c XX 1
Second device:
mknod /dev/ntibm1 c XX 2
mknod /dev/rtibm1 c XX 3
etc. etc..
You can than access the tape with mt:
E.g. mt -f /dev/ntibm0 rewind
Regards
Michael

Ira,
The "mt" command, using the ntibm? and rtibm? device names. Then you just
use tar, afio, cpio, whatever to write to the device name.

greetings all,
when i do a modprobe tape390 on the new version of SuSe i see it has tape
support and it even knows that there are two tape drives available in the
LPAR. How do i get to access and use these drives?
TIA
