Because I checked smu-service-status is "SMU status is not installed".
Contact your customer support engineer (easiest). They can install it on the head.
Note - this is only recommended for a single node and not a cluster.
If HNAS is not a member of Cluster(in case of single node), you should install smu package.
Generally... Embedded SMU is not installed on current HNAS server. If you want to setup as single node, copy ISO file(SMU Packages) to HNAS and mount ISO then run install file. or connect external CDROM to HNAS.
