MOUNT DU1: /OVERRIDE
But I still can't MOUNT an RT-11 disk pack. If I don't provide a
pack-id, there is an error.
Does an RT-11 pack have a standard ID?
Under VMS, it used to support the "/FOREIGN" switch for
INTERCHANCE, but RSTS/E does not seem to support
such a pack.
In RSTS, mounting is for mounting RSTS RDS volumes only, to be accessed
by the regular file system. For raw access, you don't have do to anything,
as long as you have privs. FIT can see the disk already.
I checked the documentation for FIT after Dave McGuire provided
the logical device name (AUXLIB$:) where FIT can be found.
(THANK YOU AGAIN, DAVE!). I do not understand why
direct access to an RT-11 disk is not mentioned. VMS requires
a MOUNT. Probably RSX-11 does as well.
In any case, the problem has been solved. BUT, DEC rarely
seemed to catch up with the extra bells and enhancements
that were needed. EVEN PUTR from dbit has the ability
to specify the PART=n when the RT-11 device is used. Why
DEC never bothered to add that trivial enhancement seems about
par for the course. The same sort of viewpoint exists in the DIR
utility in RT-11. I added value to the '/VOLUME[:value[:value...]] "
switch to support nested directories (eliminating the requirement to
MOUNT the logical disk) where the value is the block number
within the previous directory. Sometimes the solution is so trivial.
Maybe that is why a small company can be more reliable and
better equipped to produce better software.
It was not that DEC had poorly designed software - IN FACT
DEC software seemed to be about the best there ever was with
all the hooks ever needed for enhancements. But the enhancements
were so slow to arrive in many cases.
