--gateway | --nogateway
    Specifies whether the node is to be designated as a gateway node or not.
--manager | --nomanager
    Designates the node as part of the pool of nodes from which file system managers and token managers are selected. 
--nonquorum
    Designates the node as a non-quorum node. If two or more quorum nodes are downgraded at the same time, GPFS must be stopped on all nodes in the cluster. GPFS does not have to be stopped if the nodes are downgraded one at a time.
--perfmon | --noperfmon
    Specifies whether the node is to be designated as a perfmon node or not.
--nosnmp-agent
    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.
