A customer cannot enable storage failover. You have verified that the cabling is correct, the HA partners can communicate with each other, and cluster HA is configured. What must you do to resolve the

Setting HA state in the boot menu is typically for initial setup or recovery from a major HA configuration loss, not for an issue when cluster HA is already configured.

Option 4 in the boot menu performs a configuration cleanup and disk initialization, which is a destructive action and not appropriate for troubleshooting an SFO enablement issue.

The cluster type (switched or switchless) is generally established during initial HA configuration, and if cluster HA is configured, this setting would already be in place.

Epsilon is a crucial element for quorum and proper failover functionality in a NetApp ONTAP HA pair. If epsilon is not correctly assigned or maintained, the cluster cannot guarantee data integrity during a failover event, thereby preventing storage failover from being enabled or operating, even if other HA prerequisites are met. Modifying or assigning epsilon in privilege advanced mode is often necessary to resolve such issues.
