You can assign a single SCSI host port worldwide port name (WWPN) to only one volume group per storage image, unless the host type is Sun servers. For any host type that is not Sun servers, you must define an additional WWPN for every additional volume group that you plan to assign. For Sun servers host type, each volume group that you assign to the same host port WWPN must connect through a different storage image I/O port.
Ensure that you have selected the correct host type. If the correct host type is not Sun servers, enter a quantity of volume groups that does not exceed the quantity of storage images defined to the storage complex that you have selected, and resubmit the task.
