There are several circumstances in which your system may operate in an unexpected
manner. This section explains many of these circumstances and offers one or more
workarounds for each situation.

General Situations
Table 4-1, General Driver Situations, identifies some of the common situations and their
potential resolutions.
Table 4-1 General Driver Situations
Situation Resolution
Port link fails to come up. If an FC link fails to come up, verify that an 8 Gb/s
adapter is not attempting to connect to a 1 Gb/s
device. Only 2, 4, and 8 Gb/s devices are supported
on 8 Gb/s adapters.
For OCe10100-series adapters, ensure that the
fabric port is enabled.
The Emulex driver is not loaded and all
paths are down. Use lspci to determine if the Emulex ports are being
properly identified. If not, find out if the driver iso
was correctly installed. You must have the correct
driver for the installed adapter because the device
PCI IDs are installed with the driver package.
Examine the /var/log/vmkernel.log file for lpfc820
log messages indicating an error. In this case
contact Emulex support.
The LPFC driver fails to recognize an
adapter and logs “unknown IOCB”
messages in the system log during
driver load. The adapter is running
outdated firmware. Download and install the adapter firmware that
complies with the minimum supported revision (or
later) listed on the Emulex website.
System panics when booted with a
failed adapter installed. Remove the failed adapter and reboot.
