Yes, thanks, I had just arrived at the same conclusion.

The 342x is too old to respond with any sense data telling its device
characteristics. It would require a driver where you could hard code the
values before it would work.

Mark,
I made the determination by looking at the code and by experimenting. I
attached a 3422 tape drive to a Linux guest at virtual device 181,
attached a 3490 tape drive at virtual device 182, and entered "modprobe
tape390 tape=181-182" on the Linux system. After the modprobe, the
contents of /proc/tapedevices is:
TapeNo DevNo CuType CuModel DevType DevMod BlkSize State Op
MedState
1 0182 3490 10 3490 40 auto UNUSED ---
UNLOADED
And under /dev/tape there is only a 0182 device.
The driver found the 3490 tape drive, but not the 3422 tape drive.

When you say the current driver "appears to only support" 34x0 tapes,
did you determine that by experimenting? I looked at the code and
didn't see anything referring to 3420, but I don't have any 3420 drives
to test and see if it works anyway.

Subject: Linux for zSeries 3420 Tape driver
Is there a Linux for zSeries 3420 tape driver? We have an occasional
requirement to copy reels to cartridges. z/VM 5.1 is dropping support
3420 tape drives. I'm investigating whether 3420 tape drives could be
attached to a Linux guest as unsupported VM devices, and then use Linux
commands to copy the tape reels to tape cartridges. The IBM Linux tape
driver appears to only support 3480/3490 tape drives. My web searches
for a 3420 tape driver have failed.
