The process you're referring to is called the Auto-Sync Process. When a new Fabric Interconnect is added to a Cisco UCS domain, this process automatically synchronizes its firmware version with the existing Fabric Interconnect, ensuring both are running the same version.
Here's how it works:
New Fabric Interconnect Added: A new Fabric Interconnect is physically connected to the existing Fabric Interconnect in the UCS domain.
Firmware Version Check: The new Fabric Interconnect automatically detects the firmware version running on the existing Fabric Interconnect.
Synchronization: If the firmware versions differ, the Auto-Sync process initiates a firmware upgrade or downgrade on the new Fabric Interconnect to match the version on the existing one.
Completion: Once the firmware versions are synchronized, the new Fabric Interconnect becomes fully operational within the UCS domain.
Why other options are incorrect:
Firmware Policy Process: This refers to the overall management of firmware versions and updates within the UCS domain, not the specific process of automatic synchronization between Fabric Interconnects.
Auto-Negotiate Process: This is a networking protocol used to establish communication parameters between devices, not related to firmware upgrades.
Firmware Update Process: While this is a general term for updating firmware, it doesn't specifically describe the automatic synchronization between Fabric Interconnects.
