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
