 Full path SPC, where an SPC is a collection of paths with each path containing a
combination of logical unit (volume), initiator port (host port), and target port. Use
ExposePaths and HidePaths methods for adding/hiding this kind of path.
 Default SPC, where an SPC is a collection of paths with each path containing a
combination of
SCSIProtocolEndpoints (target port) and StorageVolume (LU), and
whatever host WWN/iSCSIName (StorageHardwareID) the target port is connected to.
Volumes in this kind of SPCs are exposed to any host that are connected to the target port.
In 3PAR parlance, this is termed a port-present VLUN. Each target port on an InServ node
controller has a default SPC associated with it. Each default SPC is associated to an
AuthorizedPrivilege which is then associated to a StorageHardwareID with a null
StorageID property. There is only one instance of null-StorageID
StorageHardwareID
per InServ system. Use the ExposeDefaultLUs and
HideDefaultLUs methods for adding/hiding this kind of path.
 SPC with no Target Ports, where an SPC is a collection of paths with each path containing
a combination of host collection (
StorageHardwareIDCollection) and
StorageVolume (LU), and whatever target port the host is connected to. Volumes in this
kind of SPCs are exposed to the specified host collection regardless of which target port it is
connected to. This in 3PAR terms is called host-sees VLUN. Use the
ExposeLUsToStorageHardwareIDCollection and
HideLUsFromStorageHardwareIDCollection methods for adding/hiding this kind of
path.
