Richard,        
        We don't use the DIRMc option, because our policies are simple
enough that the default management class is the right place to put the
directories, and they all go to the same media, which in this case is
virtual tape.  
        I don't know much about ACLs or GPFS, except I have checked with
our admins and I know we aren't using them.  So although those are both
excellent thoughts and I thank you for the suggestion, I don't think
they apply to my case.
        I will try your suggestion with Q CONTENT and go through the
actlog to see what tapes are getting mounted for what sessions.  I will
post again if I learn anything interesting. 


Best Regards,

Your original email included "Win2003 clients".
If you are now discounting their participation and focusing on only
the AIX client sessions, then it's possible that they are using ACLs
(particularly for GPFS), where DIRMc considerations could be a factor.
In any case, why leave this a mystery when you can readily examine the
physical evidence, as per my last posting, and get a real sense of
what's going on in those sessions?  It's possible that collocation
values are contributing to this.
