Removing nodes from management GUI-related node class

If you are reinstalling IBM Storage Scale, in some scenarios you might need to remove some nodes from the node classes that are used by the management GUI.

For information about these node classes, see Node classes used for the management GUI. If you want to remove the GUI designation of a node, you must remove it from the GUI_MGT_SERVERS node class. After you remove a node from this node class, it is no longer designated as a GUI node and GUI services are not started on this node after reinstalling IBM Storage Scale. To remove a node from the GUI_MGT_SERVERS node class, use the mmchnodeclass command only when the GUI services are not running.

On the node that you want to remove from the GUI_MGT_SERVERS node class, run the following commands:

systemctl stop gpfsgui
mmchnodeclass GUI_MGMT_SERVERS delete -N guinode

These commands stop the GUI services and remove the GUI node from the GUI_MGT_SERVERS node class.

Note: If you use mmchnodeclass to change the GUI_MGT_SERVERS node class while the GUI services are running, the management GUI adds the removed node to the GUI_MGT_SERVERS node class again.
