Reinhard,
My mistake, no the file iostat.25nov was not in a HSM filesystem. I tested the
dsmmode option in a HSM filesystem and it works. Thanks for all your help.
I hope in any case IBM will change their ADSM backup/archive client so that it
shall not change the access time of files in a HSM filesystem.
Regards
Gerrit
