For each non-director-class platform 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 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 Admin Domain restrictions that may be in place. Refer
to chapter 1, "Understanding Admin Domain Restrictions" 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 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 filesystem. 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 non-bladed 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.
host Specify a valid FTP or SSH server name or IP address. IPV4 and IPv6
addresses are supported. The firmware is downloaded from the specified
host. If a host is not specified, the firmware is considered accessible on a
local directory. To mention an FTP server by name, a DNS server must first be
set up with the dnsConfig command. If DNS is enabled and a server name is
specified, firmwareDownload automatically determines whether IPv4 or IPv6
should be used.
user Specify a user name for FTP or SSH server access. This operand can be
omitted, if the firmware is accessible on a local directory, a USB device, or by
anonymous FTP server access. A user name other than “anonymous” is
required for SSH server access.
