The IBMzOS_SBProtocolEndpoint class is used to represent two different entities, Initiator and Target. The Initiator entity describes the protocol endpoint on the computer system side, the target entity describes the protocol endpoint on the disk controller side of a logical disk attached to a computer system.

Protocol endpoints are identified via World Wide Port Numbers (WWPN), which are used as the primary key for the instances of the class IBMzOS_SBProtocolEndpoint, reflected in the name property. For the retrieval of WWPN the IOS services IOSCDR and IOSCHPD have been extended for z/OS 2.1 to facilitate the retrieval of WWPN for the Initiator (IOSCHPD) and Target (IOSCDR) protocol endpoints. Therefore, the retrieval of WWPN through IOSCDR is only possible under the following conditions:

1. The used hardware is at least an IBM® System z10™.
2. The requestor or CIM client has UPDATE access to the IOSCDR profile.
