HX,
You can certainly use an Updating Template to update FW, but personally I wouldn't recommend it. I'm very cautious using updating templates for anything other than items that dont require a blade reboot (such as add/remove VLANs). The only time customers use FW policies linked to their service profiles is if their OS/Application requires a specific version of Adapter/CIMC/BIOS FW.
To update a service profile with FW you need to create a Host Firmware policy (for BIOS, Adapter and Board Controller FW), and a Management FW policy for CIMC FW. Once you have both policies you set the Management & Host Firmware policies in the service profile or Updating template accordingly in the "Policies" tab.
You can also use a Maintenance Policy along with a schedule to post-phone any changes to either a calendar date/time or until the change is acknowledged by a user implicitly.
The config guides will have the syntax and how to do each task, but we don't have a speficic doc detailing just what I mentioned above.
Test it out so you know the implications of using Updating Templates and the behavior of applying changes.
Regards,
Robert
