are designed to share drives. Before you install a drive that would allow two
systems to share it, check that the systems and their software support sharing. If
your software does not support sharing, note that Fibre Channel switches have a
zoning capability to form a SAN partition. For systems that do not cooperate, use
zoning to prevent the systems from sharing the same drive. You can remove zoned
partitions as you upgrade software and system levels.
