If you don't use SSP all the luns would be available to all hosts. <BR />You arn't trying to use GFS are you? Or to present the same lun to multiple hosts? <BR />Additionally, you should be using Switch zoning to segment the devices from each other to prevent scsi resets of one device from causing other devices to reset. <BR />You should look for the HP SAN Design document in the MSA section.
