22 .SH DESCRIPTION
23 .sp
24 .LP
25 The \fBfwflash\fR command writes a binary image file to supported flashable
26 devices attached to a Solaris host. It also provides the ability to read
27 firmware to a file if supported by the device. Because changing the firmware in
28 a device can have significant impact on the stability of a system, only users
29 with the privilege \fBAll\fR are allowed to execute this command. Users
30 authorized to run \fBfwflash\fR can be granted the "Firmware Flash Update"
31 Rights Profile.
32 .sp
33 .LP
34 The first form of the command, above, provides information about devices. It
35 lists all devices currently available on the system that are supported by
36 \fBfwflash\fR for firmware upgrade. You can filter the list operation, to
37 display only specified classes of devices. The second form of the command
38 provides the operations to read or write the firmware images to specific
39 devices.
40 .SH OPTIONS
41 .sp
42 .LP
43 The following options are supported:
44 .sp
45 .ne 2
46 .na
47 \fB\fB-c\fR \fIdevice_class\fR\fR
48 .ad
49 .sp .6
50 .RS 4n
51 An optional parameter, valid only when used with the \fB-l\fR option. This
52 option causes the command to list only devices of a specific class type.
53 Currently supported classes are \fBIB\fR, \fBses\fR, \fBsesgen\fR, or
54 \fBALL\fR. If \fB-c\fR is not specified for the \fB-l\fRoption, the class
55 defaults to \fBALL\fR.
56 .RE
58 .sp
59 .ne 2
60 .na
61 \fB\fB-d\fR \fIdev_path\fR\fR
62 .ad
63 .sp .6
64 .RS 4n
65 The \fIdev_path\fR is absolute path name of the device that the user wants to
66 modify with the \fB-f\fRor \fB-r\fR operation. If the device cannot be found,
67 the command fails. If the \fB-d\fR option is specified, then either \fB-f\fR or
68 \fB-r\fR must also be specified.
69 .RE
71 .sp
72 .ne 2
73 .na
74 \fB\fB-f\fR \fIfile1\fR,\fIfile2\fR,\fIfile3\fR,...\fR
75 .ad
76 .sp .6
77 .RS 4n
78 Specify the path to one or more binary firmware image files you want to write
79 to the device. \fBfwflash\fR will verify that each file is a valid firmware
80 image for the specified device. If it is not, the command fails with an
81 appropriate error message.
82 .sp
83 If multiple firmware image files are specified, each image is verified and
84 flashed to the device in the order given on the command line. If any of the
85 specified files cannot be successfully flashed, then an appropriate message is
86 displayed.
87 .sp
88 After a new firmware image is flashed to a device, a reboot is required to
89 correctly activate the new firmware.

109 List the devices on a system available for firmware upgrade and display
110 information specific to each device or device class.
111 .sp
112 For InfiniBand (IB) devices, the list operation displays the \fBguid\fRs
113 (Globally Unique Identifier) currently set for the HCA, as well as the current
114 firmware revision installed. There are four separate \fBguid\fRs on the HCA;
115 two of them can be set with the same value.
116 .sp
117 For SCSI Enclosure Services (\fBses\fR or \fBsgen\fR) devices, an identifying
118 target-port worldwide name is displayed, if available.
119 .RE

122 .ne 2
123 .na
124 \fB\fB-r\fR \fIfile\fR\fR
125 .ad
126 .sp .6
127 .RS 4n
128 Specify the path to a file to create when reading the firmware from the device.
129 The \fB-f\fR and \fB-r\fR options are mutually exclusive.
130 .sp
131 Not all flashable devices support reading firmware images back from the device.
132 At present, only InfiniBand (IB) devices are supported for this operation. A
133 message will be displayed if the selected device does not support this
134 operation.
135 .RE

138 .ne 2
139 .na
140 \fB\fB-v\fR\fR

144 Display \fBfwflash\fR version information and exit.
145 .RE
147 .sp
148 .ne 2
149 .na
150 \fB\fB-y\fR\fR
151 .ad
152 .sp .6
153 .RS 4n
154 Valid only when a flash read (\fB-r\fR) or write (\fB-f\fR) operation is
155 specified. This option causes \fBfwflash\fR not to prompt for confirmation
156 during operation and operate non-interactively. Note that there is no option
157 that allows you to forcibly flash an incompatible firmware image onto a device.
