Hi, EDG8194I means the volume status is not "pending release" but master or user. Have you executed the following steps before EDGSPLCS SQ ? Were they successful ? Could you give me "RMM LISTVOLUME volser ALL" result ? 3. Add volume entry in RMM CDS as follows. RMM ADDVOLUME volcat

No, it does not mean. The superseding PTF is to fix the problem, but it may or may not contain the code of superseded PTF. In first case the superseding PTF should have similar ACTION. ...or not. Depending on other circumstances. And superseded PTF should not be prereq, as someone mentioned.
