One of the (in my opinion) few historic deficiencies of MVS is the inability to distinguish like-named data sets on different volumes. GRS (any mode) communicates the DSN around the complex but not the volser. You will inevitably get a conflict trying to edit two at the same time even though you know that are different. GRS does not.
Best not to remove protection for ease of editing. Disaster is the ultimate inconvenience. . .

More clearly:- when i tried to edit CLOCK00 member from LPAR A and at the same time when i tried to edit CLOCK00 member from LPARB, it says member in use though volumes are different. LPAR A:- SYS1.PARMLIB VOl=XXXXXX LPAR B:- SYS1.PARMLIB VOl=YYYYYY GRS MODE=STAR As per my understanding the i have to make change in GRSRNLxx member in both the lpars and also keep it identical. but i am confused where should i make the entry for SYS1.PARMLIB in SYSTEMS exclusion or SYSTEM inclusion and why ? (To ensure that resources are treated as you want them to be without changes to your applications, global resource serialization provides three resource name lists (RNLs): The *SYSTEM inclusion RNL lists resources requested with a scope of SYSTEM*that you want global resource serialization to treat as global resources. The *SYSTEMS exclusion RNL lists resources requested with a scope of SYSTEMS * that you want global resource serialization to treat as local resources. The *RESERVE conversion RNL *lists resources requested on the RESERVE macro that you want global resource serialization to suppress the reserve. Could any one help on this and throw some more light and make it clear. Thanks Much in Advance. -- Thanks & Regards: Sunil M "Yesterday I dared to struggle.
