NAME

6       hermon - ConnectX MT25408/MT25418/MT25428 InfiniBand (IB) Driver
7

DESCRIPTION

9       The  hermon driver is an IB Architecture-compliant implementation of an
10       HCA, which operates on  the  Mellanox  MT25408,   MT25418  and  MT25428
11       InfiniBand  ASSPs  using  host  memory for context storage  rather than
12       locally  attached memory on the card. Cards based  on these ASSP's uti‐
13       lize  the  PCI-Express  I/O  bus. These  ASSP's  support  the  link and
14       physical layers of the InfiniBand specification while  the ASSP and the
15       driver support the transport layer.
16
17
18       The  hermon driver interfaces with  the InfiniBand  Transport Framework
19       (IBTF) and provides an implementation of the  Channel  Interfaces  that
20       are  defined  by that framework.  It  also enables  management applica‐
21       tions and agents to access the IB fabric.

DIAGNOSTICS

65       In addition to being  logged, the following  messages may appear on the
66       system console:
67
68       hermoni: driver attached for maintenance mode only.
69
70           There  was a failure in the boot  process of  the  hermon ASSP  and
71           the only function that can be performed is to re-flash  firmware on
72           the  ASSP.  (Note  that  i  represents   the instance of the hermon
73           device number.)
74
75
76       hermoni: driver failed to attach
77
78           The ASSP could not boot into either   operational   (HCA)  mode  or
79           into maintenance mode. The device is inoperable. (Note that  i rep‐
80           resents  the instance of the hermon device number.)
81
82
83       Unexpected port number in port state change event.
84
85           A port state change event occurred, but the port   number  in   the
86           message does not exist on this HCA. This message also indicates the
87           port number that was in the port state changed.
88
89
90       Hermon driver successfully detached.
91
92           The driver has been removed from the  system  and  the  HCA  is  no
93           longer available for transfer operations.
94
95
96       hermoni: port m up.
97
98           A port up asynchronous event has occurred. (Note that  i represents
99           the  instance of the Hermon device number while "m" represents  the
100           port number on the Hermon device.
101
102
103       hermoni: port m down.
104
105           A  port  up  asynchronous  event  has  occurred. Similar to port up
106           event.
107
108
109       hermon: <command name> command failed.
110
111           A internal firmware command failed to execute.
