We face a lot of problems recently with LAN-FREE on MS Windows platform. The TSM server runs on AIX or HP-UX, but the client is always MS Windows. Sometimes we lose one or a few drives, sometimes all of them. The problem doesn't evolve immediately only after a while. For these problematic customers we use J1A, E05 or LTO3 drives with the newest firmwares and drivers, of course.
Does anyone else have the same CHALLENGE?
