Some times the reset hapends whwn a few MBs are written others after a couple of hundred MBs but only when we use the LTO5 ([2:0:0:0] tape IBM ULT3580-TD5 C7RC /dev/st1 ) the LT03 always works grate.

the linux kernel running is :
Linux bacula 3.2.0-4-amd64 #1 SMP Debian 3.2.46-1 x86_64 GNU/Linux

and the bacula-sd configuration for LT05 tape:

Hello,

2013/8/19 Iban Cabrillo <cabrillo AT ifca.unican DOT es>

Hi, Any Idea?
Seems something related to bacula, I have tried chaging the FC port, but the result has been the same

FC LIP reset is not related to Bacula - IMHO. I had the same problem but with a changer device. The problem was a second server which accidentally accessed the same target (at random time). When I switch off the second server the problem was cured. Sure, your problem could has a different origin then my, and YMMV. BTW, what kernel tape driver do you use (Linux stock)?

best regards
