Configuring Cluster Export Services nodes

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

If not already done during the installation, this must be done before configuring any protocols. Nodes that should participate in the handling of protocol exports need to be configured as CES nodes.

Note: You can have a maximum of 16 nodes in a CES cluster.

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

mmchnode -N nodename –-ces-enable

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

mmces node list

CES nodes may be assigned to CES groups. A CES group is identified by a group name consisting of lowercase alphanumeric characters. CES groups may be used to manage CES node and address assignments.

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

mmchnode --ces-group group1 -N node

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

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

The group assignment may 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 may 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.
