You can use switch zoning to
expose logical units that
are on your existing storage to the cluster.
You must create a cluster before you can use switch zoning
to expose logical units.
Important: Ensure that logical
units are not zoned or mapped so that they are detected by the SAN Volume Controller and
a host at the same time. Ensure that all of the logical units can
be detected by all of the SAN Volume Controller nodes that are in the cluster on both storage area networks
in a redundant fabric.
