During a VPLEX installation, the front-end ports are enabled after the metadata volumes and backup have been created. This sequence ensures that the system’s metadata, which is crucial for the operation of VPLEX, is secured before the storage is exposed to the hosts.
Metadata Volumes Creation: The first step in the VPLEX installation process involves creating metadata volumes. These volumes store configuration and operational data necessary for VPLEX to manage the virtualized storage environment1.
Metadata Backup: After the metadata volumes are created, it is essential to back up this data. The backup serves as a safeguard against data loss and is a critical step before enabling the front-end ports1.
Enabling Front-End Ports: Once the metadata is secured, the front-end ports can be enabled. These ports are used for host connectivity, allowing hosts to access the virtual volumes presented by VPLEX1.
Exposing Storage to Hosts: With the front-end ports enabled, the storage can then be exposed to the hosts. This step involves presenting the virtual volumes to the hosts through the front-end ports1.
Final Configuration: The final configuration steps may include zoning, LUN masking, and setting up host access to the VPLEX virtual volumes. These steps are completed after the front-end ports are enabled and the storage is exposed1.
In summary, the front-end ports are enabled during a VPLEX installation after the metadata volumes and backup have been created, which is reflected in option D. This ensures that the system metadata is protected and available before the storage is made accessible to the hosts.
