Basically these are system specific OMVS data sets.  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.
