Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

NAME
fwflash - firmware query and update utility
SYNOPSIS
/usr/sbin/fwflash [-l [-c device_class | ALL ]] | [-v] | [-h] fwflash [-f file1,file2,file3,... | -r file] [-y] [-d device_path]
DESCRIPTION
The fwflash command writes a binary image file to supported flashable devices attached to a Solaris host. It also provides the ability to read firmware to a file if supported by the device. Because changing the firmware in a device can have significant impact on the stability of a system, only users with the privilege All are allowed to execute this command. Users authorized to run fwflash can be granted the "Firmware Flash Update" Rights Profile. The first form of the command, above, provides information about devices. It lists all devices currently available on the system that are supported by fwflash for firmware upgrade. You can filter the list operation, to display only specified classes of devices. The second form of the command provides the operations to read or write the firmware images to specific devices.
OPTIONS
The following options are supported: -c device_class An optional parameter, valid only when used with the -l option. This option causes the command to list only devices of a specific class type. Currently supported classes are IB, ses, sesgen, or ALL. If -c is not specified for the -loption, the class defaults to ALL. -d dev_path The dev_path is absolute path name of the device that the user wants to modify with the -for -r operation. If the device cannot be found, the command fails. If the -d option is specified, then either -f or -r must also be specified. -f file1,file2,file3,... Specify the path to one or more binary firmware image files you want to write to the device. fwflash will verify that each file is a valid firmware image for the specified device. If it is not, the command fails with an appropriate error message. If multiple firmware image files are specified, each image is verified and flashed to the device in the order given on the command line. If any of the specified files cannot be successfully flashed, then an appropriate message is displayed. After a new firmware image is flashed to a device, a reboot is required to correctly activate the new firmware. -h Display the command line usage message for fwflash. -l List the devices on a system available for firmware upgrade and display information specific to each device or device class. For InfiniBand (IB) devices, the list operation displays the guids (Globally Unique Identifier) currently set for the HCA, as well as the current firmware revision installed. There are four separate guids on the HCA; two of them can be set with the same value. For SCSI Enclosure Services (ses or sgen) devices, an identifying target-port worldwide name is displayed, if available. -r file Specify the path to a file to create when reading the firmware from the device. The -f and -r options are mutually exclusive. Not all flashable devices support reading firmware images back from the device. At present, only InfiniBand (IB) devices are supported for this operation. A message will be displayed if the selected device does not support this operation. -v Display fwflash version information and exit. -y Valid only when a flash read (-r) or write (-f) operation is specified. This option causes fwflash not to prompt for confirmation dur- ing operation and operate non-interactively. Note that there is no option that allows you to forcibly flash an incompatible firmware image onto a device.
EXAMPLES
Example 1 Entering Command Without Arguments The following command shows fwflash when the command is entered without arguments. example# fwflash Usage: Usage: fwflash [-l [-c device_class | ALL]] | [-v] | [-h] fwflash [-f file1,file2,file3,... | -r file] [-y] -d device_path -l list flashable devices in this system -c device_class limit search to a specific class eg IB for InfiniBand, ses for SCSI Enclosures -v print version number of fwflash utility -h print this usage message -f file1,file2,file3,... firmware image file list to flash -r file file to dump device firmware to -y answer Yes/Y/y to prompts -d device_path pathname of device to be flashed If -d device_path is specified, then one of -f <files> or -r <file> must also be specified If multiple firmware images are required to be flashed they must be listed together, separated by commas. The images will be flashed in the order specified. Example 2 Listing Devices Available to Flash The following command lists the devices available to be flashed. example# fwflash -l List of available devices: Device[0], /devices/pci@0,0/pci8086,3595@2/pci8086,32a@0,2/\ pci15b3,5a46@c/pci15b3,5a44@0:devctl Class [IB] GUID: System Image - 0002c901081e33b3 Node - 0000000000003446 Port 1 - 0002c901081e33b1 Port 2 - 0002c901081e33b2 Firmware revision: 3.3.0002 No hardware information available for this device Device[1], /devices/pci@0,0/pci8086,3597@4/pci15b3,6278@0:devctl Class [IB] GUID: System Image - 0002c9010a99e3b3 Node - 0002c9010a99e3b0 Port 1 - 0002c9010a99e3b1 Port 2 - 0002c9010a99e3b2 Firmware revision: 4.8.00c8 Product : MTLP25208-CF256T (Lion cub) PSID : MT_00B0000001 Alternatively, for a SAS Expander presented as a SCSI Enclosure Services device , we might see output such as this: example# fwflash -l List of available devices: Device[0] /devices/pci@0/pci@0/pci@2/scsi@0/ses@3,0:ses Class [sgen] Target port WWN : 500605b00002453d Vendor : SUN Product : 16Disk Backplane Firmware revision: 5021 Example 3 Flash Upgrading an IB HCA Device The following command flash upgrades an IB HCA device. example# fwflash -f ./version.3.2.0000 \ -d /devices/pci@0,0/pci8086,3597@4/pci15b3,6278@0:devctl About to update firmware on: /devices/pci@0,0/pci8086,3597@4/pci15b3,6278@0:devctl Continue (Y/N): Y Updating . . . . . . . . . . . . Done. New image will be active after the system is rebooted. Note that you are prompted before the upgrading proceeds and that it is mandatory that you reboot your host to activate the new firmware image. The following command adds the -y option to the command. example# fwflash -y -f ./version.3.2.0000 \ -d /devices/pci@0,0/pci8086,3597@4/pci15b3,6278@0:devctl About to update firmware on: /devices/pci@0,0/pci8086,3597@4/pci15b3,6278@0:devctl Updating . . . . . . . . . . . . Done. New image will be active after the system is rebooted. Example 4 Reading Device Firmware to File The command shown below reads the device firmware to a file. The command uses the -y option so that read occurs without prompting. example# fwflash -y -r /firmware.bin \ -d /devices/pci@1d,700000/pci@1/pci15b3,5a44@0:devctl About to read firmware on: /devices/pci@1d,700000/pci@1/pci15b3,5a44@0:devctl to filename: /firmware.bin Reading . . . Done. Example 5 When No Flashable Devices Are Found The command output shown below informs the user that there are no supported flashable devices found in the system: example# fwflash -l fwflash: No flashable devices attached with the ses driver in this system fwflash: No flashable devices attached with the sgen driver in this system fwflash: No flashable devices attached with the tavor driver in this system fwflash: No flashable devices in this system Each plugin found in /usr/lib/fwflash/identify is loaded in turn, and walks the system device tree, determining whether any currently- attached devices can be flashed. For the list of device types and drivers that are currently supported, please see the NOTES section below.
