Abstract

See full text

Disclosed is a computer implemented method, data processing system and computer program product to discover an SCSI target. The method comprises a client adapter transmitting an N_port ID virtualization (NPIV) login to a virtual I/O server (VIOS). The client adapter receives a successful login acknowledgement from the VIOS and issues a discover-targets command to the fabric. Upon determining that the SCSI target information is received, wherein the SCSI target information includes at least one SCSI identifier. Responsive a determination that SCSI target information is received the client adapter issues a port login to a target port, wherein the target port is associated with the at least one SCSI target. The client adapter makes a process login to form an initiator/target nexus between a client and at least one SCSI target. The client adapter queries the SCSI target by using a world wide port name associated with the target port.
