During a controller upgrade (e.g., //X to //XL), the puresetup script attempts to migrate network configurations from the old controller's ports to the new controller's ports. If the script detects that certain ports configured on the source array are physically missing or "link down" on the target array, it halts to prevent a configuration mismatch that could cause a service outage.
The error message explicitly lists the affected ports. The correct resolution path is to:
Identify the services: Determine if the missing ports are critical (e.g., a replication link that hasn't been cabled yet) or non-critical (e.g., an unused interface).
Re-run with override: Execute the puresetup command again, this time appending the specific flags or arguments (often suggested in the error output or upgrade guide) to explicitly acknowledge and include those affected ports. This tells the script, "I know these ports are down/missing; proceed with the migration anyway." This allows the upgrade logic to complete the configuration transfer so the new controller can boot, after which the engineer can physically troubleshoot the link status.
