digits, periods, and underscores, up to a maximum of 64 characters. The services configuration option of
the cluster_config utility provides an interface that enables you to manipulate node attributes in the
database.
Individual nodes can be disabled as servers or disabled as clients of specific services. You must create a
node attribute before you can add it to a node.
The following services configuration commands are available:
[S]ervices Config, [P]roceed, [Q]uit: S
Commands are:
[l]ist - List by attribute
[n]odes - List by node
[c]reate attr - Create new attribute
[d]estroy attr - Destroy existing attribute
[a]dd attr node(s) - Add attribute to node(s)
[r]emove attr node(s) - Remove attribute from node(s)
[w]ipe - Remove/destroy all attributes
[s]ervices - List service assignments
[h]elp - Show help
[b]ack - End services config, return to cluster_config
Examples:
create na_disable_server.cmf
add na_disable_server.cmf n1 n4
remove na_disable_client.supermond n3
destroy na_disable_client.supermond

Command Syntax
The following list contains examples of command syntax:
• Create a node attribute (na) to disable a node or nodes as a server of the named service:
svcs> create na_disable_server.service_name
• Create a node attribute to disable a node or nodes as a client of the named service:
svcs> create na_disable_client.service_name
Example: Disable a Server from Serving a Service
To disable node n3 as a server of the cmf service, add the node attribute na_disable_server.cmf to
node n3. This is how you could remove one of several nodes from the list of cmf servers if you wanted that
specific node not to serve that service, even though it was configured to do so by default.
Example: Disable a Client
Similarly, to disable node n1 as a client of the supermond service, enter the node attribute
na_disable_client.supermond to the affected node. In this instance, it is not the server but a client
of the service that is affected.
Creating and Adding Node Attributes
Using the previous two examples, enter the following commands to create and add node attributes:
svcs> create na_disable_server.cmf
Attribute "na_disable_server.cmf" created
svcs> create na_disable_client.supermond
Attribute "na_disable_client.supermond" created
svcs> add na_disable_server.cmf n3
Attribute "na_disable_server.cmf" added to n3
svcs> add na_disable_client.supermond n1
Attribute "na_disable_client.supermond" added to n1
svcs>
