Les and JR, Firstly : Thanks to gave me the info 'PMH 84921,004,000'. I asked our hardware to l ook at this. I don't have a feedback yet.
Secondly : I was able to IPL our z/VM530 today and ... - from z/VM440, I ipled z/VM530 2nd lvl and did a test about the target : nothing changed. Problem still alive :( - I ipled z/VM530 1st lvl and did a test, then did it again and again to be absolutely sure. I washed my glasses and yes our problem disappeared. NO MORE PROBLEM !!! So it was not a hardware problem. Glad to see this has been corrected in the z/VM version. Regards Thanks to both for your contiguous support Alain Benveniste
