Examples below show mounting the DECUS 11-424 disk image 110424.dsk
under the MSCP driver unit 1 (aka rq1 in SIMH).
The easiest way to access a RT-11 logical disk is with RT-11. No
FLX to run because RT-11 makes everything easy. e.g. after booting RT-11
[ctrl-E]
sim> att rq1 110424.dsk
sim> c

But under say RSX-11M+ you can also access using FLX, e.g. after booting
RSX-11M+:
[ctrl-E]
