tar and tape media interchange?

» close window

The Question is:

 
Sharing DLT media with AIX and OpenVMS. I can
read the media from the AIX machine using
VMStar but I can not read a VMStar tape
from the AIX machine. I think it's because
I need to initialize the tape before I can use it
on the VMS box. I don't want
to initialize the tape because this appears to
causing problems
for the AIX machine. I've tried using
init/interchange but it still requests a
VMS label. Please help. Maybe you can't help
with VMStar but how about init/interchange syntax?
How's it's used, etc.
 
Thanks Wizard!
 
 

The Answer is :

 
  There are other potential tools available for this purpose
  if VMSTAR is causing a problem, including various other
  versions of tar (see the Freeware) for OpenVMS.
 
  You need to determine what ANSI labels are used by (or are
  required or prohibited by) the AIX system, if any.  (ANSI
  labels are little more than records written to the tape
  using specified formats.)  Please see the Guide to OpenVMS
  File Applications manual for further details.
 
  INITIALIZE/INTERCHANGE simply prevents OpenVMS from writing
  VOL2 labels to the tape during the initialization, under the
  assumption that the receiving system cannot handle (or cannot
  ignore) these particular ANSI labels correctly.
 
  Other considerations include the use of MOUNT vs MOUNT/FOREIGN,
  tape compression used, etc.
 
  You may simply be able to skip over the ANSI tape labels on AIX.
