Abstract:
A system and method for migrating a client partition between computer electronic complexes (CECs) while maintaining access to a Storage Area Network. An active and inactive world wide port name are generated for a client virtual channel adapter. A query is sent to a name server from the VIOS on the source CEC. The name server creates a list of small computer system interface (SCSI) targets that are available. The list is used by the VIOS on the destination CEC to verify whether any physical ports in the destination CEC have access to the same SCSI target. The client partition may be migrated between a source CEC and a destination CEC and the access to the Storage Area Network access may be maintained.
