pmartyn: As Mr. Scherrer noted, you're new here, and possibly new to preparing comments on forums like this one. Perhaps you should just look for a few weeks, learn who writes reasonably intelligent posts, and who sends in reasonably intelligent queries. NicC has been providing valuable assistance for years; he is "senior" to me, for example, and I've been writing these posts for more than 10 years, here and elsewhere.
Sadly, surime72 is not noted for intelligent queries. For example, it does not seem likely this query even belongs in JCL; surime72 did not provide the "JCL" (if any), or the complete error message, including the message ID.
You, and all of us, for that matter, should be careful about guessing, I've had more than one case of foot in mouth disease from a bad guess, and I can't even guess how often I've written a long post - and then discarded it when I realized it was just another case of foot in mouth disease.
One more thing, don't tag on comments for "older" topics, such as this one. This one started February 12, and NiC's post directing surime72 to consult with his storage management people was the only quick response (and probably the only intelligent response that could be made), and then it went silent until you chimed in. It is unlikely the topic starter (TS is often used here) (surime72) is even interested any more.
