Once it is on 2nd level, you have to ATTACH / DEDICATE to whatever

You have to have it assigned to your 2nd level VM Guest on 1st level,

Can OpenExtension commands, for example, GETBFS, PUTBFS, MOUNT, etc be
issued from within a REXX program?
The OE Users Guide doesn't say that you can, but it doesn't say that you
can't.
The code might be something like:

The number should be set to the number of FCP subchannels you expect to
divy out to different Linux guests and VM EDEVICE definitions (plus some
extras). If you don't know, just set it to the max supported for the
CHPID; that should be either 240 or 480 depending on your adapter card
level.
If you get the 1010, you might want to issue: TERM CONMODE 3270

Thanks
VM is very effective about keeping low priority work in the
background. If you see that one user seems to be hogging the system, it
is probably because there are spare cycles that nobody else wanted to
use. The caveat is that on a fully loaded system, even that work does
get its fair share of CPU
