CIM API Programming Reference
 ResultDescriptions[]: An array of descriptive text of the result of the operation, with each
entry containing the result of each expose path operation. This parameter is a vendor-
specific extension for 3PAR.
Parameters “Override” and “NoVCN” are optional. All other combinations of the parameters
are rejected.
There are two use cases of the
ExposePaths() method (See Table 5-58 on page 5.111 for
details).
 Creating a new view: export a list of volumes to a list of host HBAs via specific target
port. This creates a “matched-set” VLUN. This case is indicated by NULL input
ProtocolController parameter.
 Add InitiatorIDs to view: add another initiator ID (host path) to a view. The new initiator
port must be zoned with the same target port as that used by the view or else the
operation is rejected.
