When importing from a dual-SP (Storage Processor) system like a VNX2, providing the IP address for one SP (e.g., SPA) establishes the initial connection. Selecting the "Verify Alternate Address" option instructs PowerStore to also validate the connectivity and security credentials (like the HTTPS certificate) of the second SP (SPB). This ensures that if the primary SP becomes unavailable during the import, the session can seamlessly fail over to the alternate SP, thus maintaining high availability for the migration process.

A. The PowerStore Global Storage Discovery IP is an internal PowerStore address used for node discovery within the cluster, not for connecting to an external VNX2 system.

B. This action validates the existing certificate on SPB; it does not generate or duplicate any RSA keys from SPA. Each SP has its own unique security credentials.
