Abstract
Executing connections from a data processing system to a storage controller using ports specified in a TPG report. The storage controller receives a RTPG SCSI request from the data processing system via a FC fabric. The storage controller determines whether NPIV is enabled on the storage controller and, if so, the storage controller modifies the TPG report to include one or more dedicated N-Ports and one or more multi-purpose N-Ports, where AAS bits of a dedicated N-Port descriptor associated with the dedicated N-Ports are set as Active/optimized. The storage controller sends the modified TPG report to the data processing system. The storage controller then processes an access request received from the data processing system where the access request is received on one of the one or more dedicated N-Ports and the one or more multi-purpose N-Ports according to the TPG report and a device type of the data processing system.
