NAME

hermon - ConnectX MT25408/MT25418/MT25428 InfiniBand (IB) Driver

DESCRIPTION

The hermon driver is an IB Architecture-compliant implementation of
an HCA, which operates on the Mellanox MT25408, MT25418 and MT25428
InfiniBand ASSPs using host memory for context storage rather than
locally attached memory on the card. Cards based on these ASSP's
utilize the PCI-Express I/O bus. These ASSP's support the link
and physical layers of the InfiniBand specification while the ASSP
and the driver support the transport layer.


The hermon driver interfaces with the InfiniBand Transport
Framework (IBTF) and provides an implementation of the Channel
Interfaces that are defined by that framework. It also enables
management applications and agents to access the IB fabric.

DIAGNOSTICS

In addition to being logged, the following messages may appear on
the system console:

hermoni: driver attached for maintenance mode only.

There was a failure in the boot process of the hermon ASSP
and the only function that can be performed is to re-flash
firmware on the ASSP. (Note that i represents the instance of
the hermon device number.)


hermoni: driver failed to attach

The ASSP could not boot into either operational (HCA) mode or
into maintenance mode. The device is inoperable. (Note that i
represents the instance of the hermon device number.)


Unexpected port number in port state change event.

A port state change event occurred, but the port number in the
message does not exist on this HCA. This message also indicates
the port number that was in the port state changed.


Hermon driver successfully detached.

The driver has been removed from the system and the HCA is no
longer available for transfer operations.


hermoni: port m up.

A port up asynchronous event has occurred. (Note that i
represents the instance of the Hermon device number while "m"
represents the port number on the Hermon device.


hermoni: port m down.

A port up asynchronous event has occurred. Similar to port up
event.


hermon: <command name> command failed.

A internal firmware command failed to execute.
