CMMVC7241E System code update cannot start because a component firmware update is in progress.
Explanation
An attempt was made to initiate either a system code update or a
firmware update while the system was updating the firmware of various hardware components. This
update cannot be completed while a firmware download is in progress, so the request
failed.
User response
The firmware download must complete before you can perform another update. Due to the dynamic nature of firmware downloads, you cannot follow the progress of the download. Wait approximately 10 minutes and retry the command. You might need to repeat this step several times. You can use the svcinfo lsupdate command to see whether the firmware download completed.
