elements specified in the other parameters. This is mandatory only because SMI-S requires
it. For InServ, access permissions cannot be specified when creating a VLUN. Rather, each
volume has its own access permission. So the 3PAR
ControllerConfigurationService
provider checks the passed in
DeviceAccesses value against the permission of the
specified LU (volume), and the operation fails if the two values do not match.
 ProtocolControllers[]: An array of references to SCSIProtocolControllers (SPCs). On
input, this can be null, or contain exactly one default SPC; there may be multiple references
on output. If null on input, the instrumentation creates one or more new SPC instances, but
these new SPC instances are NOT default SPCs, in the sense that they have associations to
host HBA WWN/iscsiName as well as to target ports and the exposed volumes.
 Override: Override existing lower priority VLUNs, if necessary. Can be used only when
exporting to a specific host. This parameter is a vendor-specific extension for 3PAR. The
default value is false.
 NoVCN: Do not issue a VLUN (Virtual Logical Unit Number) Change Notification (VCN) after
export. For direct connect or loop configuration, a VCN consists of a fibre channel Loop
Initialization Primitive (LIP). For fabric configuration a VCN consists of Registered State
Change Notification (RSCN) being sent to the fabric controller. This parameter is a vendor-
specific extension for 3PAR. The default value is false.
 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.
