3. Guidelines for key scenarios:

1. Storage network adjustment: Make sure that the storage network interfaces of all nodes use IP addresses that belong to the same network segment. After the adjustment, check whether data in virtual storage is synced.

2. VXLAN interface adjustment: Adjust the configuration of physical switches at the same time, such as enabling jumbo frames, to avoid VXLAN communication errors.
