for rooted logicals you can use:

$MOUNT/system dka100: myvolume MYDISK

$define/system/trans=(term,conc) myroot 'f$trnlnm("MYDISK")'[users.]


This translates MYDISK to the physical device name before the DEFINE
command executes so DEFINE sees whatever device MYDISK points to. So you
get the volume shadowing DSA100: to mount and define MYDISK. Gradually
change all references in your system from DSA100: to MYDISK including
those areas that require physical device (with the F$TRNLNM trick). Once
that is done, you can then change the mount command to no longer create
a shadow set and mount the disk directly and the system will
transparently adapt.
