Typically you need to have devices online so the OS will see them at startup. But for
removable media devices (tapes and many disks) you may want to mount the media (image
files) later on, and switch them at runtime, exactly as you would do with disk packs or
tape reels on a real computer.

I thought you set all devices you planned to use "online" so you could
mount them later? I don't simh vax much so thanks for the correction as to
the procedure. I mostly do pdp8 or pdp11 stuff, or esoteric hardware.
