HPE has Provided very good utility called hpacu or (HP Array Configuration Utility) which is available in GUI and CLI for managing Local Hard disks of all HPE Servers and connected DAS (Direct Attached Storage) like HPE MDS 600.
It can easily be downloadable from HPE Driver and Firmware Website or also can come in SPP (Service Pack for Proliant) which ship with HPE Server. For more detail check your HPE Server documentation.
