After executing the puredb run giveback --safe command during a manual controller upgrade or specific non- disruptive upgrade (NDU) procedure, the Implementation Engineer must wait for 10 minutes before proceeding to the next step (typically upgrading the peer controller).
The giveback command instructs the recently upgraded controller (e.g., CT0) to resume its primary role and take back ownership of its assigned storage resources and I/O handling from the peer controller. This process triggers a failover event for the host multipathing software.
* Path Stabilization: The 10-minute wait time is a critical safety buffer mandated to ensure that all host- side multipathing drivers (MPIO) have successfully recognized the restored paths to the upgraded controller and have stabilized.
* Risk Mitigation: Proceeding too quickly-before the hosts have fully settled and paths are marked as
"Active/Optimized"-could lead to an "all paths down" (APD) scenario when the second controller is taken offline for its upgrade. This wait time verifies that the upgraded node is fully functional and carrying load, adhering to the strict "availability first" philosophy of FlashArray upgrades.
