You use the Enable DARE option to enable data-at-rest
encryption for volumes.
This option appears on the Version & Services page of the
web-based Installer when the Enable Secure Cluster option is selected. The
Enable DARE
option is deselected by default.
For more information about data-at-rest encryption, see Encryption in Data Fabric.
Considerations for Enabling DARE Using the Installer
Before using the
Enable DARE option, review these considerations:
Important: Once enabled, the Enable DARE option cannot be disabled, since disk encryption cannot
be turned off without reformatting the disks.
- The Enable DARE option can only be used during the initial
installation of a cluster or during an incremental
install.
- You cannot select the Enable DARE option when:
- The Enable Secure
Cluster option is deselected.
- You perform an upgrade operation using the Installer. Security changes are not allowed during an upgrade using the Installer.
- If you select the Enable DARE option, you can no longer deselect the
Enable Secure
Cluster option during an Incremental Install
operation.
