Good point, thanks. I conclude that for a multi-platform environment, TSM for SAN is required for all systems that need LAN-free data movement. Another vague issue for me is the shared resource. Evidently, tape libraries could be shared SAN resources. How about disk-based ones? What I have found is that disk-based resources could be shared using some products such as GPFS (for AIX and linux), Tivoli SANergy or IBM Totalstorage SAN Filsysetem. How TSM server defines storage pools on a shared disk or filesystem?
Thanks.
