update command

This command updates firmware using the uniform resource locator (URL) of a TFTP, FTP, HTTP, HTTPS, or SFTP server and displays information about firmware installed in Lenovo Flex System components.

Attention

Installing the wrong firmware update might cause the CMM to malfunction. Before you install a firmware update, read any readme and change history files that are provided with the downloaded update. These files contain important information about the update and the procedure for installing the update, including any special procedure for updating from an early firmware version to the latest version.

Important

Some cluster solutions require specific code levels or coordinated code updates. If the device is part of a cluster solution, verify that the latest level of code is supported for the cluster solution before you update the code.

Note

When the CMM is set to Secure security mode, only secure file transfer methods, such as HTTPS and SFTP, can be used for tasks involving file transfer when the CMM is acting as a server. Unsecure file transfer protocols, such as HTTP, FTP, and TFTP, are disabled when the CMM is acting as a server when the security mode is set to Secure. Unsecure file transfer protocols remain available for a CMM acting as a client for all commands when the security mode is set to Secure.
For information about how to specify a URL for file transfer, see Specifying a URL for file transfer.
The CMM update command does not support updating compute node firmware. If an optional management device, such as the Lenovo XClarity Administrator or Flex System Manager management server is installed in the Lenovo Flex System chassis, you can update compute node firmware using the management device program (see Flex System Firmware Update Guides). Depending on your compute node type, other methods are available for updating compute node firmware. See the documentation for your compute node for information.
For additional information about updating firmware for Lenovo Flex System, seeFlex System Firmware Update Guides (you might need to register to access this content).

If command syntax is not correctly entered, or if a command fails to run, an error message is returned. See Common errors for a list of error messages that apply to all commands or update command errors for a list of error messages that are specific to the update command.

Table 1. update command.
The command table is a multi-row, four-column table where each row describes a CMM CLI command option: column one lists command function, column two provides a detailed command description, column three shows command-option syntax, and column four lists valid command targets.
Function	What it does	Command	Target (see paths in Command targets)
Display firmware attributes	Displays attributes of the firmware installed in the command target. Return values are: Firmware type Build ID Filename Release date Revision level Note When the command target is the primary CMM, this command will return the values for the currently active firmware and for the pending firmware, that will become active after the next CMM reboot. For a standby CMM, the returned value will also indicate if a firmware update is in progress and the percentage that is complete. For I/O modules that support it, this command will also display firmware image information.	`update -a`	Primary or standby CMM: mm[p] mm[P] mm[s] mm[S] mm[x] where x is the primary or standby CMM bay number. I/O module: switch[x] where x is the I/O-bay number.
Update firmware using URL	Update firmware for the command target using a uniform resource locator (URL). Attention Installing the wrong firmware update might cause the CMM to malfunction. Important Command authority definitions might change between firmware versions. Make sure that the command authority level set for each user is correct after updating CMM firmware (see Commands and user authority). Note Updating to older firmware levels may cause loss of certain functionality. When the primary CMM firmware image is updated, the old primary image becomes the new backup image. These changes do not take effect until the CMM is rebooted. Some I/O modules support only RSA fingerprinting when updating through SFTP. See the documentation that comes with your I/O module for information.	`update -u` URL where URL is fully qualified uniform resource locator, including file name, of the tftp, ftp, http, https, or sftp server where the firmware update image is located.

Primary CMM: mm[p] mm[P] mm[x] where x is the primary CMM bay number. I/O module: switch[x] where x is the I/O-bay number.
Update firmware and reboot	Update firmware and reboot the CMM to use new firmware if the update succeeds. Attention Installing the wrong firmware update might cause the CMM to malfunction. Important Command authority definitions might change between firmware versions. Make sure that the command authority level set for each user is correct after updating CMM firmware. Note When the primary CMM firmware image is updated, the old primary image becomes the new backup image. These changes do not take effect until the CMM is rebooted.	`update -u` URL`-r` where URL is fully qualified uniform resource locator, including file name, of the tftp, ftp, http, https, or sftp server where the firmware update image is located. This command can only be run by users who have one or more of the following command authorities: Supervisor Chassis administration See Commands and user authority for additional information.	Primary CMM: mm[p] mm[P] mm[x] where x is the primary CMM bay number.
Update firmware (verbose)	Update firmware for the command target, showing details of the firmware download and flash operations. The detailed information is not shown until the update is complete, which might take several minutes. Attention Installing the wrong firmware update might cause the CMM to malfunction. Important Command authority definitions might change between firmware versions. Make sure that the command authority level set for each user is correct after updating CMM firmware. Note Updating to older firmware levels may cause loss of certain functionality. When the primary CMM firmware image is updated, the old primary image becomes the new backup image. These changes do not take effect until the CMM is rebooted. Some I/O modules support only RSA fingerprinting when updating through SFTP. See the documentation that comes with your I/O module for information.	`update -u` URL`-v` where URL is fully qualified uniform resource locator, including file name, of the tftp, ftp, http, https, or sftp server where the firmware update image is located.

Example: To update the CMM firmware from a HTTP server and reboot the primary CMM in bay 2 after a successful update, while the Lenovo Flex System chassis is set as the persistent command environment, type the following command at the system:> prompt. For this example, the IP address of the HTTP server is 10.12.100.109 and the firmware file containing the update is named cmefs.uxp that is in the flash sub-directory on the server. The verbose mode and reboot flag are also specified.

update -u http://10.12.100.109/flash/cmefs.uxp -T mm[p] -v -r

The following example shows the information that is returned from the update command:

system> update -u http://10.12.100.109/flash/cmefs.uxp -T mm[p] -v -r
