Hi,

we have a HP FC HBA (AJ763B, which is OEM from Emulex Lpe12000) we try to use with SLES 12 SP3.
But we have constantly intermittent connection. /var/log/messages says:

The HBA is currently running in a usual desktop pc. When booting that system with different knoppix versions the HBA runs fine and i have connection to the SAN. I tried the most recent drivers from Emulex and HP:
elx-lpfc-kmp-default-11.4.142.26_k4.4.73_5-1.sles12sp3.x86_64
and 11.4.142.21-1. Same error. The HBA is also running fine on a ProLiant Server with SLES 11 SP4.
I’m a bit desperate because i’d like to get it running on SLES 12 SP3 but i’m running out of ideas.
Firmware is also up to date. I changed the optical fibre, no improvement.

Thanks for any help.

Bernd
