FWIW, $ ld help connect /lbn

/LBN=(START=X,COUNT=y)

 Connect an LD device to a physical disk, starting at LBN x, with either
 an end-lbn specified or a count. The ending lbn may not be beyond the
 end of the physical device. The count plus the starting lbn may also
 not be beyond the end. With this qualifier it is possible to partially
 map a physical disk.


And yes, the VMS virtual disk driver, VD, could/can do this as well.
