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

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.
