Caution
  • This function cannot be used under the following conditions:

    • The operation mode for the storage system is not in "Maintenance Mode"

    • The controller firmware is being received from the REMCS center or another storage system

    • The controller firmware is registered for the current generation only

Note

  • This function can be used to delete both controller firmwares (dedicated controller firmware for a SAN system, and a unified firmware (*1)).

    *1  :  A controller firmware with built-in Unified Storage functions.
  • After the upgrade of the SAN system to a Unified Storage system has been successfully completed, a dedicated controller firmware for SAN becomes unnecessary. To delete the dedicated controller firmware for SAN, the following confirmations and operations are required.

    • Perform an offline update of the unified firmware twice. Confirm that the unified firmware is registered in both ECs (EC#1 and EC#2).

    • Use this function to delete the dedicated controller firmware for SAN (up to two generations).

      Note that the unified firmware and the dedicated controller firmware for SAN cannot be distinguished by the firmware version. Select the controller firmware generation that is not displayed as "EC#1" or "EC#2" in the Active field.
