Subj: RE: DEC Alpha/SGI tapes
Wayne,
I am not sure about the exact formatting of the SGI tapes you are writing.
Assuming you are writing a tar formatted tape, and the tar on SGI is
reasonably standard the following web site has a Utility to untar your
tapes.
http://www.openvms.digital.com/openvms/freeware/cd.html
Under the label "Utilities", you will find "ACCESS TOOLS, Tools for Vax
and Alpha for unzip, untar, etc. operations". This or other things at this
site should do the trick.
Please tell me if this gets you going.
Your call log # is 3386-1997

Subj: RE: DEC Alpha/SGI tapes
Wayne,
VMSTAR is the tool I had in mind which would do the trick. We do not
have experience with the details regarding why the SGI tapes might not
be readable by this utility.
The one thing which comes to mind is that the VMSTAR utility is
expecting the tape to have a particular blocking factor. This is the
"b" switch in most tar facilities.
Do you also have the help file for VMSTAR? It discusses it a bit. To
answer your quesstion directly, no we don't have experience with
transferring
from SGI to VMS.

Subj: RE: Blocking factor.
Wayne,
I just did a basic tar from Digital UNIX, ftp'd the file to OpenVMS VAX,
and VMSTAR/EXTRACT'ed it fine. The blocking factor is 20 (=10240 in
VMSTAR).
The blocking factor on SGI is the same (by default). Maybe this was
changed?
One other alternative is that teh POSIX subset of OpenVMS has tar in it as
well (the license is in the OpenVMS kit, but it needs to be loaded). Since
the group here is focused on code migration issues, and not really around
operational issues such as this, I'm not sure how much we can help you on
this matter.
For example, I can imagine a number of sources for the problem:
o tape block factor not 20 on the UNIX side (10240).
o the tape written on a high density drive on SGI,
and the TLZ09 not recognizing it.
o the tpae was not written with the tar command (ie:dd,
or other on the UNIX side?).
Please explain what the specific requirement is in this case. Do you need
to convert this one tpae, or is it something you will need to do regularly?
If it is a one-off, we have UNIX systems, and could copy the data to VMS,
and make you a backup saveset.
Regards,
Jeff Kenyon

Subj: DEC Alpha/SGI tapes
Thanks for your suggestions regarding the use of VMSTAR to exchange 4mm tapes
with an SGI machine. I am sure that the SGI tape was written with tar; and
that an SGI machine can not read a tape written with VMSTAR. I do not need
this capability often, but I need it more than once, so I still hope to find
a solution.
I have discussed the problem with people at NASA who use VMS and are active
in DECUS. They can duplicate the problem between DEC and SGI workstations,
but do not have a solution yet either.
