Is it worth the work? Are there any VTLs involved? I may be doing 4 TSM servers to 18x 3952's, 8x LTO6 shared drives and 120x LTO1's for each server non-shared in multiple DataDomains. I also have LANFree clients that do not support redundant fabrics.

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. ----- Original Message ----- Is anyone using redundant tape SAN with TSM on AIX?
