.SH NAME
hermon \- ConnectX MT25408/MT25418/MT25428 InfiniBand (IB) Driver
.SH DESCRIPTION
.sp
.LP
The \fBhermon\fR 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.
.sp
.LP
The \fBhermon\fR 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.

\fBhermon\fBi\fR: driver attached for maintenance mode only.\fR
.ad
.sp .6
.RS 4n
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
\fBi\fR represents  the instance of the hermon device number.)

\fBhermon\fBi:\fR driver failed to attach\fR
.ad
.sp .6
.RS 4n
The ASSP could not boot into either  operational  (HCA) mode or into
maintenance mode. The device is inoperable. (Note that \fB i\fR represents  the
instance of the hermon device number.)

.RS 4n
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.
