If volumes are SMS, all datasets must be cataloged and the
associated catalogs must be accessed from any system that accesses
those datasets. If the systems are not in a relationship that
enables proper catalog sharing, access and possible modification of
the catalog from multiple systems causes the cached versions of
catalog data to become out of sync with actual content on the drive
when the catalog is altered from a different system, and there is a
high probability the catalog will become corrupted on all systems.
Let me sharpen that last point. If the catalog is being updated from
more than one system not in a sysplex, it's not a "high probability",
it's basically a certainty The really fun part is that you may not
discover the catalog corruption for days, weeks, or even months.
