Possibly the fiber cable?  Can you swap it out and try again?
I had 20 fiber connections and one of them needed replacing.  It made the drive look bad from the server, but the library did not report any error conditions with the drive.

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<mailto: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
