Configuring Cluster Export Services nodes

If you do not configure Cluster Export Services (CES) nodes through the installer, you must configure them before you configure any protocols.

If not already done during the installation, configuration of CES nodes must be done before you configure any protocols. Nodes that participate in the handling of protocol exports must be configured as CES nodes.

Note: A CES cluster has a maximum of 32 protocol nodes if only NFS is enabled and a maximum of 16 protocol nodes if both SMB and NFS are enabled.

For each of the nodes that handle protocol exports, run:

mmchnode -N nodename –-ces-enable

After you configure all nodes, verify that the list of CES nodes is complete:

mmces node list

CES nodes can be assigned to CES groups. A CES group is identified by a group name that has lowercase alphanumeric characters. CES groups can be used to manage CES node and address assignments.

Nodes can be assigned to groups by issuing the following command:

mmchnode --ces-group group1 -N node

A node can be assigned to multiple groups by issuing the following command:

mmchnode --ces-group group1,group2,group3 -N node1,node2

The group assignment can also be specified when the node is enabled for CES by issuing the following command:

mmchnode --ces-enable --ces-group group1,group2 -N node

The node can be removed from a group at any time by issuing the following command:

mmchnode --noces-group group1 -N node

For more information, see mmchnode command.
