Machine Data Encryption Settings can be enabled by the following procedure.
When setting up encryption, specify whether to start encryption after deleting data (initialize) or encrypt and retain existing data. If data is retained, it may take some time to encrypt it.
When the Machine Data Encryption Settings is enabled;
If the HDD is replaced, HDD data will be deleted. After installing the new HDD, the data in the new HDD will be automatically encrypted.
If the NVRAMs on the controller board are replaced, Machine Data Encryption Settings will be automatically enabled after installing the new NVRAMs.
If the controller board is replaced, the restore key will be required after installing the new controller board.
If you have the restore key, you will be able to continue using the HDD data.
If the restore key has been lost, the HDD will be formatted and you need to reset NVRAM data to the default settings after the forced start-up. (HDD data will be deleted) Refer to "How to do a forced start up with no encryption key" in "Encryption Key Restoration" (Encryption Key Restoration
).If the controller board and the NVRAMs are replaced together, HDD data will be deleted since all the encryption information is deleted.
