Hi,

As soon as I try to add new tapes to the same fc, I'm not able to see them. The zoning is correct, tapes are running correctly on the library side, no error on syslog.

I suspect something related to a maximum number of "something" reached, and in particular I suspect about the "255" in the fc path

Really, I can't say from where "255" comes up.

Reboot changes nothing, and I continue to have new added SAN tapes out of my system, and I cannot see the reason.

Any suggestion from you folks ?

Thanks a lot in advance for your support!

It indicates the devices are loop connected (this is normal) - what kind of library is it? You probably need to do some "presentation"!
