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

To delete the dedicated controller firmware for SAN, the following confirmations and operations are required.

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