Disabling an embedded SMU

It is possible to disable the embedded SMU on a NAS platform (unless the GAD Enhanced for NAS feature is enabled, in which case the embedded SMU will already be disabled).

Before disabling an embedded SMU, ensure that there is an external SMU available to manage the cluster and to send updates to any Hitachi Device Manager (HDvM) that may be managing the cluster.

To link an external SMU to your HDvM, in the NAS Manager, navigate to the Home > Storage Management > Hitachi Device Managers page and add a server. This is valid on all file servers prior to NAS Platform Series 5000.

To disable an SMU, use the following command:

smu-service-disable

The command requires confirmation (y/n).

After confirming the disabling of the SMU service:

  • the smu-service-status command shows the SMU status as "disabled" on both nodes.
  • the embedded SMU is not accessible.
  • viewing the Cluster Status page on an external SMU shows a grey status button with text "Disabled" for the embedded SMU.
  • the embedded SMU is no longer listening on ports 80 or 443. See the Network Administration Guide for further details.
