Do VMS and ODS-2 really try to figure out a geometry per disk for MSCP disks???
The ODS2 utility needs to "mount" the disk. I know nothing, but ODS-2 on VMS probably only cares about LBNs and VBNs (and on on-disk data structures). It is the mount utility which knows or needs to know the geometry, to do the geometry based search for alternate home blocks (there is also a non-geometry based search algorithm). And the mount utility probably uses the same code as the init utility, which writes the alternate home blocks. And both probably request the information from some other (driver) code level.
