If I'm not wrong, MOUNT/BIND does not work if more than one disk contains
files. In other words, when you bind a number of disks, you'll see only =
files
located in the first one. Bind was conceived when physical disks were so =
small
that some applications space needs exceeded single-disk capacities =
available.
HELP MOUNT /BIND says:

It depends. You can't just put files on disparate disks and then, issue a
MOUNT/BIND and expect to see them as one happy family. The files on ODS-n
disks have a file identifier. The identifier is composed of three values
which represent the file: <NUM(24bits), SEQ(16 bits), RVN(256 bits). The
RVN is Relative Volume Number. If a volume is not bound, the RVN is zero.
If you were to try to /BIND your volumes, the file system would not know
where these files exist.
