You can update the entire system in a coordinated process with no user intervention after the update is initiated.
Before you update your system, review all of the topics in Updating to understand how the process works. Allow adequate time, such as up to a week in some cases to look for potential problems or known bugs. Additional information on updating the system is available at the following websites:

When the system detects that the hardware is not running at the expected level, the system applies the correct firmware.
If you want to update without host I/O, shut down all hosts before you start the update.
Monitor the update information in the management GUI to determine when the process is complete.
If the process stalls during the update, click Resume to continue with the update or click Cancel to abandon the update and restore the previous level of code. You can also use the CLI command applysoftware -resume to resume the update.
