     Stops the SNMP subagent and specifies that the node should no longer serve as an SNMP collector node. For more information, see GPFS SNMP support.
 --quorum
+    Designates the node as a quorum node.
+    Note: If you are designating a node as a quorum node, and adminMode central is in effect for the cluster, you must ensure that GPFS is up and running on that node (mmgetstate reports the state of the node as active).
+--snmp-agent
+    Designates the node as an SNMP collector node. If the GPFS daemon is active on this node, the SNMP subagent will be started as well. For more information, GPFS SNMP support.
+--ces-enable
+    Enables Cluster Export Services (CES) on the node.
+--ces-disable
+    Disables CES on the node.
+--ces-group=Group[,Group...]
+    Adds one or more groups to the specified nodes. Each group that is listed is added to all the specified nodes.
+--noces-group=Group[,Group...]
+    Removes one or more groups from the specified nodes.
