Will reply with different detail on the LINUX-390 list, where this was cross posted.
The only ATTACH/DETACH in the traditional sense would be the FCP channels. They work a lot like ethernet adapters. Think of them as OSAs and things begin to make more sense. But they are called "channels" in SAN land. So then, the tape drives in question are "out there" in the storage area network. Attaching those is a different concept than CP ATTACH or DETACH.
Are you running a z9? If not, then all of your Linux guests will look like the same mainframe to the SAN.

We are thinking about buying some IBM 3592-E05 tape drives for the Open
System group (well, actually, it's comming out of their budget), and we
will put them in our, yet to be purchased IBM 3494 robotics unit. The
tape drives will be dedicated to a FC SAN thingie.
Apparently, we can attach the mainframe to the FC SAN thingie, using
FCP connections. Then, zLinux can have access to them.
As FCP tape drives are not known to VM. And I have some 20-30 Linux
images running under VM, what is the procedure to attach/detach these
tape drives to each image?
Or is it something stupid, like I have to dedicate the drives to one
machine and then backup over vswitch from one machine to another to the
tape drives? (I say stupid, as backing up over "communications" usually
takes more resources than backing up over hardware....directly to the
drives.)
