Fabric OS Command Reference 333
53-1001764-02
firmwareDownload
2
For each standalone switch in your fabric, complete all firmware download changes before issuing
the firmwareDownload command on the next switch to ensure a nondisruptive download.
If firmwareDownload is interrupted due to an unexpected reboot as a result of a software error or
power failure, the command automatically recovers the corrupted secondary partition. Wait for the
recovery to complete before starting another firmwareDownload.
Notes Firmware download and subsequent POST failure may occur on certain platforms (the Brocade AP
blades FR4-18i, FA4-18, FC4-16IP, and the Brocade 7500 and 7600 switches) when the
firmwareCommit operation coincides with the execution of POST. The recommended work around is
to disable POST (diagDisablePost) before you initiate a firmware download and re-enable POST
(diagEnablePost) after the firmwareCommit is complete.
On certain occasions, you may see messages in the console output of firmwareDownload .These
are internal messages generated by the Linux utilities. You can safely ignore these messages. For
relevant Brocade-generated firmware download messages, refer to the Fabric OS Message
Reference (SULB module).
Firmware download procedures may vary depending on which Fabric OS version you are migrating
from. See the Fabric OS Administrator's Guide "Firmware Download" chapter for restrictions on
changing Fabric OS versions.
To correlate Brocade blade names with blade IDs, use the slotShow command.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command
Availability" for details.
Operands The following operands are optional. When invoked without operands, the command goes into
interactive mode.
-U Downloads the firmware from an attached USB device. This option is valid
only on platforms that support a USB port. Refer to your specific Hardware
Reference Guide for details. The USB device must be enabled prior to
firmware download with the usbStorage command. Firmware must be stored
under the /firmware directory in the USB file system. On a dual-CP chassis,
the USB device must be attached to the active CP. When downloading
firmware from a USB device, the -p option is ignored.
-s Enables single-CP mode. This mode supports selectively enabling or disabling
a full install, autoreboot, and autocommit on bladed and nonbladed systems.
On enterprise-class platforms, this mode supports upgrading a single CP.
When downloading the main Fabric OS firmware, this option disables
autoreboot, unless overridden by the -b option.
-b Enables autoreboot mode. When single CP mode is enabled and this operand
is not specified, reboot must be run manually to activate the downloaded
image. If autoreboot mode is enabled, the switch reboots automatically after
the firmware has been downloaded.
-n Disables autocommit mode. When autocommit mode is disabled, the
firmwareCommit command must be executed manually to propagate the
downloaded image to both partitions of the storage device.
