Would EMC's Storage Scope solve that problem by auto-discovering the LUNs?
Many storage array vendors use proprietary data in the SCSI header to differentiate their arrays and provide information on array type. Any SRM product can give you free space information and device supplier from the SCSI Inquiry String information, but to do anything more requires integration with the proprietary application programming interfaces (APIs) and infrastructure from the array or storage provider.
I know that Veritas has done a lot of work with their Command Central Storage software to integrate with the leading storage arrays and provide detailed LUN and storage information.
I don't know about EMC's Storage Scope, other than the marketing materials that EMC has made available, but it should provide the base information like any other SRM product.
I hope that my response was helpful.
