Hello,

I have the next components:

- One Mezzanine Card (BX600-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 !
