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.

Thank you,

Andy Huebner

Subject: Re: [ADSM-L] Redundant Tape SAN

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.

Is anyone using redundant tape SAN with TSM on AIX?
