Supported Methods Table 66 (page 76) - Table 68 (page 76) shows the supported methods of the masking and mapping subprofile: Table 66 Methods for TPD_StorageSystem Method modifyInstance() Description Provides the ability to set owner and contact information for the StorageSystem. Table 67 Methods for TPD_StorageHardwareIDManagementService Method CreateStorageHardwareID() DeleteStorageHardwareID() CreateStorageHardwareIDCollection() DeleteStorageHardwareIDCollection() Description Expose SCSI Logical units. Hide a list of SCSI logical units. Create a collection of StorageHardwareIDs. Delete a collection of StorageHardwareIDs. Table 68 Methods for TPD_ControllerConfigurationService Method ExposePaths() HidePath() ExportDefaultLUs() HideDefaultLUs() ExposeLUsToStorageHardwareIDCollection() HideLUsFromStorageHardwareIDCollection() Description Expose SCSI Logical units. Hide a list of SCSI logical units. Expose a list of SCSI logical units (such as RAID volumes) through a "default view" SCSIProtocolController (SPC) through a list of target ports. The "default view" SPC exposes logical units to all initiators. This SPC is identified by an association to a StorageHardwareID with Name property set to the empty string. Hide a list of SCSI Logical Units (such as RAID volumes) through a default view SCSIProtocolController through a list of target ports on a default view SCSIProtocolController. Expose a list of SCSI logical units to a list of StorageHardwareIDCollections (hosts). Hide a list of SCSI logical units through a list of StorageHardwareIDCollections (hosts). SMI-S View and Paths Storage arrays usually provide a means for the administrator to specify which initiators can access what volumes via what logical unit number (LUN). The goal is that a given volume is only accessible to SCSI commands originated from the specified initiators through specific sets of target ports. The ability to limit access is called Device Masking. The ability to specify the device address (LUN) seen by particular initiators is called Device Mapping. In the HP 3PAR Storage System, storage volumes must be explicitly exported to be visible to hosts or they are not accessible to any host. A view is a list of logical units exposed through a list of target ports, modeled as SCSIProtocolController (SPC) with associated StorageVolume, StorageHardwareIDs (host WWN/iSCSIName), and SCSIProtocolEndPoints (port WWNs/iscsiNames). A path is a combination of one each: logical unit (volume), initiator port (host port), and target port. An SPC serves as a collection of paths. 76 CIM API SMI-S Support
