Error loading "lpfc" driver

[Joaquín Jara Atienza]

Hello,

I have the next components:

- One Mezzanine Card (FC42E / LPe1105-M4)
- RedHat Enterprise Linux 5.5 (Tikanga)
- Lpfc driver version: 8.2.0.63.3p (Inbox of RedHat)

The problem is this; When the driver tries to load the following error messages are displayed:

- Adapter failed to set maximum DMA length mbxStatus x12
- lpfc_sli_read_link_ste failed to read config region 23 rc 0xfffd Status 0xfffd

Bringing the "link" can not be established.

[root@ec] cat /sys/class/fc_host/host1/port_state
Linkdown
[root@ec] cat /sys/class/fc_host/host2/port_state
Linkdown

My "/etc/modprobe.conf";

alias scsi_hostadapter2 lpfc
options lpfc lpfc_log_verbose=0xffff lpfc_use_msi=1 lpfc_topology=2 lpfc_scan_down=0 lpfc_devloss_tmo=60 lpfc_sli_mode=0 lpfc_link_speed=0 lpfc_pci_max_read
=4096

I have seen the documentation and this error can be solved by modifying the "lpfc_pci_max_red". I tested the four possible (512, 1024, 2048, and 4096) values, and none has solved this error.

Can you help me please?

If you need more information will provide you the happy!

Thanks !

All the modules declared with "alias scsi_hostadapter" and "alias scsi_hostadapterN" lines are included in initrd and loaded before the root filesystem is mounted. This is because without (at least one of) them, the root filesystem won't be accessible.

If you did not create a new initrd file after editing your /etc/modprobe.conf, your initrd file still uses the old, un-edited version of /etc/modprobe.conf that was included in the initrd file when your current kernel was installed.

You should now update your initrd file:

mv /boot/initrd-$(uname -r).img /boot/initrd-$(uname -r).img.old
mkinitrd /boot/initrd-$(uname -r).img $(uname -r)

Also note that all the lpfc_... options should be listed in one long "options lpfc ..." line. If the lpfc_pci_max_read option is on a different line, it won't work.

Hello, thanks for you answer.

I forgot to indicate in the message above also created a new "initrd" in every modification of the file "/etc/modprobe.conf" by the some procedure that you show me.

I delete some options, the file "/etc/modprobe.conf" new is as follows:

[root@ed] # more /etc/modprobe.conf
       alias eth0 tg3
       alias eth1 tg3
       alias eth2 tg3
       alias eth3 tg3
       alias eth4 tg3
       alias eth5 tg3
       alias scsi_hostadapter mptbase
       alias scsi_hostadapter1 mptsas
       alias scsi_hostadapter2 lpfc
       alias scsi_hostadapter3 usb-storage
       # Emulex lpfc options
       options lpfc lpfc_log_verbose=0xffff lpfc_pci_max_read=4096

Again I tested the four possible options for "lpfc_pci_max_read" and continued with the same problem.

Attached the output of "dmesg | grep -i lpfc" executed on the initial system.

Thank again !!!

It seems that the file not attached. Stick it (sorry);
