PowerStore Manager is the dedicated HTML5-based management user interface for the Dell PowerStore family. All administrative, monitoring, and service tasks, including hardware component management, are performed through this interface. To replace a drive, a technician must first use PowerStore Manager to identify the specific drive, verify its status, and execute the "Prepare to Remove" service action. This action safely takes the drive offline, ensuring data integrity before the physical component is removed from the appliance.
