No SAN connection with the latest kernel

Postby silvio » 2018/05/18 07:51:13

Hi,

we have some bl465c G7 blades with Emulex cnas.
These devices uses the be2net and lpfc drivers for network and fc connections.
I reinstalled one of the blades with an 1511.iso (i know it's old but the DVD is in the bladecenter and installing systems over Ilom is a ...) and all is working.
After yum upgrade to the latest version, i lost the connection to the SAN.
In the bootlog i can see this:

May 17 17:52:52 blade-server-16 kernel: Command line: BOOT_IMAGE=/vmlinuz-3.10.0-862.2.3.el7.x86_64 root=UUID=c02e6a02-88ed-4757-a57d-b36a581b85ea ro rhgb quiet LANG=de_DE.UTF-8
...
May 17 17:52:55 blade-server-16 kernel: lpfc 0000:04:00.2: 0:1412 Failed to set up driver resource.
May 17 17:52:55 blade-server-16 kernel: lpfc 0000:04:00.2: Driver probe function unexpectedly returned 16
May 17 17:52:55 blade-server-16 kernel: lpfc 0000:04:00.3: 0:1412 Failed to set up driver resource.
May 17 17:52:55 blade-server-16 kernel: lpfc 0000:04:00.3: Driver probe function unexpectedly returned 16

I don't know if this only happens in this kernel version, because i switch directly from 3.10.0-514 to 3.10.0-862.2.3 .
Have someone seen the same problem and have a solution?
