The only time that BPXPRMxx is used to mount a filesystem is at IPL time, so unless the system that is trying to perform the mount is IPLing then someone is trying to manually mount this filesystem. If it is at IPL time you should be getting an 'BPXF237I FILE SYSTEM.....Already mounted' message, not the IGW026I. Are you sharing one BPXPRMxx member within the SYSPLEX? We have two members for every system, a SYSPLEX BPXPRMxx for filessytems that should be shared and a System-specific BPXPRMxx for system-specific filesystems. All of the filesytems in the system-specific BPXPRMxx are defined with 'unmount'.

They would not be mounted on any other system because that system already has these files. I will look at UNMOUNT, however, there is no one trying to move these files. It looks to me to be the system trying to do this. I get an IGW026I indicating the system tried to mount LPAR1 dataset on LPAR2 but could not because it was already in use. It is just strange to me that the system is trying to mount a file it should not care about. >From my SMPE environment I have the ZOS19.OMVS.JV390 dataset. I then copy it as SYS1.OMVS.JV390.LPAR1 and SYS1.OMVS.JV390.LPAR2 and so forth. So I have 5 copies of the smpe JV390 dataset. For some reason during its run time, the operating system seems to feel the need to mount this dataset (say SYS1.OMVS.JV390.LPAR1) on LPAR2. But LPAR2 already has this data set mounted as SYS.OMVS.JV390.LPAR2, and LPAR1 is not down and still has SYS1.OMVS.JV390.LPAR1 mounted. It is then I see the IGW026I message.
