On my now beautifully working uVAX II (thanks again
Allison!) I
have a Cipher 9trk and a TK50... I have the MIcro VMS User's Manuals
VOL I & II. I understand the concept of mounting the devices and
allocating them (sort of), and I have successfully loaded, mounted,
allocated, and initialized a roll of tape on the Cipher. I have made
a Test directory on the HD called [TEST] ;} on which I have created
a couple of simple text files. I have tried to copy these files to
the tape (MSA0:), and it does *something*, the tape advances and the
HD led flickers, but when I try to copy these files back, all I get
are sequentially numbered blank directory entries.
Some very important questions that need to be answered:
1. Which version of VMS?
2. What commands did you use? The *exact* commands, with all qualifiers.
You know, it is *very* hard for us to tell what you did wrong unless
you tell us exactly what you did! It sounds like you may have
very well mounted the tape /FOREIGN, in which case there is no
file name associated with each file. (See the ANSI labeled tape
spec for more details about what /FOREIGN isn't doing for you :-) )
I mounted/foreign an RT-ll sig tape, and tried to
copy it to the
HD; same thing. Show/Dev/MSA0: shows the right Volume Label.. but
the directories are empty when I copy them back...
Again, what commands? If you MOU/FOR the tape, by default there
is no "file name" associated with each file, and on a copy back you
will get files named "." (apparently what you are seeing).
When dealing with RT-11 (not ll!) tapes under VMS, please keep
in mind the very detailed advice in the RT-11 "Volume and File
Formats Manual", pages 1-37 through 1-39.
Finally, don't forget "/LOG" if you want to know what each
COPY command is really doing for you :-).
As a basic test of ANSI labeled tape functionality under VMS, try this:
INIT MSA0: TEST (if it complains, use /OVER=(ID,ACCESS) )
MOUNT MSA0: TEST
COPY LOGIN.COM MSA0:
DIR MSA0:
COPY MSA0:LOGIN.COM []LOGIN2.COM

Thank you Tim... I have written a 7" reel of tape with the word
"D'OH!" several thousand times, and I am now wearing it as I type. ;}

I didn't look at this one.. I will experiment.

Will try this a bit later, (after dinner).

Some very important questions that need to be answered:
1. Which version of VMS?
5.4 maj id=1, min id=0
2. What commands did you use? The *exact* commands,
with all qualifiers.
You know, it is *very* hard for us to tell what you did wrong unless
you tell us exactly what you did!
You know, I wasn't exactly looking for precise commands (re-read
my post, just general info and 'why not try this' type of stuff.
More the algorithmic side... how tape is logically different from
disk.. to help me understand where the appropriate command apply...
but I will copy herewith according to your wishes:
It sounds like you may have
very well mounted the tape /FOREIGN, in which case there is no
file name associated with each file. (See the ANSI labeled tape
spec for more details about what /FOREIGN isn't doing for you :-) )
And 'The ANSI labeled tape spec' is available where.... ?
I mounted/foreign an RT-ll sig tape, and tried
to copy it to the
HD; same thing. Show/Dev/MSA0: shows the right Volume Label.. but
the directories are empty when I copy them back...

Easier kept in mind when the mind in question actually has *access*
to the aforementioned document; this one does not. :( (refer to
original post. I have only the VMS User's Guide and the "help" system
on the machine. I also scanned thru my RT-11 Orange Wall, but didn't
find it in there, either.. I will look again when off-line.

Also, Tim... if DEC Hard Drive test-sets are of interest to you, I
have three which are taking up Space... they are looking to be
adopted for the price of shipping... e-mail me privately and we can
go from There.
Cheers and Thanks
