Class CIM_iSCSISession
extends CIM_NetworkPipe

iSCSISession is a network pipe between an initiator and target SCSIProtocolEndpoints. An iSCSISession is composed of one or more TCP connections which MUST be selected from a SystemSpecificCollection representing an iSCSI Portal Group. NetworkPipeComposition aggregates NetworkPipe instances representing iSCSI connections, which are associated to TCPProtocolEndpoints. Only an iSCSI initiator can create an iSCSI Session, an iSCSI Target MUST accept (or reject) a session request. EndOfNetworkPipe associates iSCSISession with SCSIProtocolEndpoint.
