Thank you for your response.
Referencing your Using z/VM in a SCSI Environment presentation from WAVV May 2007 you have the following: IODEVICE ADDRESS=(5400,128)... Why 128? Aside from guest access channel limits per channel what are the effects, if any, of setting this lower or higher? This is what I could not find.

They are not the actual disk volumes. They are portal devices, much like how OSA subchannel devices are to an IP network. The FCP subchannels are all you will configure in HCD or IOCP. The actual disk volumes are configured either in Linux or VM via the WWPN of the storage controller port and the LUN name associated with the actual volume. Please see one of my SCSI presentations on my developer website for more info: http://www.vm.ibm.com/devpages/wilkinss/ I would recommend the WAVV 2007 version. Regards, Steve.
