71.0. "Strange behavior with SAVESET COPY" by CSC32::B_KNIGHTEN () Tue May 27 1997 14:58

  
   Help!

   I have a customer who said upon performing a SAVESET COPY
   of 3 input tapes, after the first tape filled up, at 10:45am
   OPCOM prompted him to mount the second tape as follows:
      Request from User SLS, Mount Relative Volume 2
   
   He then received the following message 3 minutes later (10:48)
      Request 382 Remount Relative Volume 1

   My customer would like to know what conditions would cause
   SSMgr to request the first volume again. He does not want
   to retry the procedure, and he does not know if he received
   a message from OPCOM stating that the first Request had been
   satisfied.

   Thanks,

71.1remount for completing wildcard loopSSAG::SNYDERThere are no shortcutsTue May 27 1997 15:2335
    The customer was doing a wild card copy/all, right?  Something like:
    
    $ saveset copy mka100:*.* mka200:*.*/all
    
    SSMgr can't know that it's made it all the way through the save sets
    until the wildcarding loop is complete.  The MagTape ACP will ask that
    the first volume of a multivolume set be remounted if it doesn't find a
    file that it's looking for.  In this case, it would be the first file
    copied, which completes the wildcard loop.  If the customer responds to
    the OPCOM request, issued by the MagTape ACP, by remounting Relative
    Volume 1 of the input set, the operation will complete normally as soon
    as that first file is detected.
    
    I'm a bit confused about the OPCOM messages, though.  You say: 
    
    >   I have a customer who said upon performing a SAVESET COPY
    >   of 3 input tapes, after the first tape filled up, at 10:45am
    >   OPCOM prompted him to mount the second tape as follows:
    >      Request from User SLS, Mount Relative Volume 2
    
    Is that a request to mount relative volume 2 of the input tape volume
    set or the output tape?  You say, "after the first tape filled up," so
    I assume you mean the second output tape.  The actual OPCOM message
    would indicate which tape device it was referring to.
    
    Then comes the next request:
    
    >   He then received the following message 3 minutes later (10:48)
    >      Request 382 Remount Relative Volume 1
    
    This, of course, must be for the input tape volume set, based on the
    conditions as described above, and the timing would be completely
    unrelated to requests for mounting a follow-on output tape.

71.2Problematic behavior explainedCSC32::G_DAVIDSONTue May 27 1997 16:502
    Turns out that the customer had asked for the savesets to be written to
    a new tape in the wrong order.Thank you for your prompt response.

    Thanks for responding Sid,
    
    Appartently, the customer has an automated procedure to
    copy savesets, and mistook the input device for the output
    device. Their automated procedure asked for the tapes
    in the wrong order, so when the saveset could not be found,
    it asked for tape 1 again.
    
    Thanks!
