We utilize a redundant tape SAN at our main data centers with multiple host site HBA ports. Using the Atape control and data path fail-over options we have twelve device entries for each physical tape device. Works really well and this is in an AIX/LPAR/VIO environment, we've virtualized the HBA ports and are using NPIV. We have some scripts created that rename each rmt entry via chdev to utilize the last four digits of the WWPN and the AIX fiber channel adapter to make things easier to line up as well when defining drives in TSM.
