To expand an existing logical enclosure based on a single HPE Synergy frame to include a second frame and ensure a highly available master setup, the following steps should be performed:
* Modify an existing logical interconnect to include the second HPE Synergy frame: This step involves updating the logical interconnect configuration to encompass the new frame, ensuring network connectivity and consistency across both frames.
* Move one of the master modules to the appropriate interconnect bay in the second frame: To achieve a highly available master setup, one of the master modules should be relocated to the second frame, providing redundancy and high availability for the management components.
