fwupdate
Description
Allows you to update the CMC rmware, chassis infrastructure rmware. You can:
• Check the rmware update process status.
• Update the rmware from a FTP or a TFTP server by providing an IP address and optional
path.
• Update the rmware from the local le system using remote RACADM.
• The subcommand updates one or more devices of a single type at a time.
To use this subcommand, you must have the Chassis Conguration Administrator privilege.
NOTE: Running the subcommand to update the CMC rmware resets the CMC,
causing all network connections to get logged o.
NOTE: The subcommand generates an error, when used on the extension slot of a
multi-slot server.
The CMC rmware performs a signature verication step to ensure the authenticity of the
uploaded rmware. The rmware update process is successful only if the rmware image is
authenticated by CMC to be a valid image from the service provider and has not been altered.
The rmware update process is stopped if CMC cannot verify the signature of the uploaded
rmware image. A warning event is then logged and an appropriate error message is displayed.
Synopsis
• Using Remote RACADM:
racadm fwupdate -p -u -d <firmware image>
NOTE: iDRAC7 targets are not supported from CMC. Use the CMC GUI to update
iDRAC7 targets from CMC.
When using FTP, if you provide the full path to the image le on the CLI, then the CMC uses
that path to locate that le on the host. If you do not provide a full path, then the CMC
searches the home directory of the specied user for the le if the host system is running
Linux or another variant of UNIX. If the host system is running Windows, then a default
folder, such as C:\ftproot is searched.
NOTE: While performing rmware update using the racadm fwupdate command,
if the number of characters in the rmware image path is greater than 256
characters, Remote RACADM session logs o with the error message ERROR:
Specified path is too long.
NOTE: While performing rmware CMC rmware upgrade if the uploaded rmware
image le does not contain a verication signature or it contains a verication
signature, which is not valid or corrupted, the following message is displayed:
Invalid firmware: The firmware image validation was
unsuccessful
NOTE: While performing CMC rmware downgrade if the computed signature of
that earlier version is not recognized by the current CMC rmware, the following
message is displayed:
Firmware downgrade is unsuccessful: a downgrade to this
firmware version is not supported
• racadm fwupdate -g -u -a 192.168.0.100 -d firmimg.cmc -m
