To perform this procedure, you need the following information about your configuration.
The names of the cluster nodes that can master the data service.
The network resource that clients use to access Sun Cluster HA for Sun ONE Directory Server. Normally, you set up this hostname when you install the cluster. See the Sun Cluster 3.1 Concepts Guide document for details on network resources.
Perform this procedure on any cluster member.
Become superuser on a cluster member.
Verify that all of the network addresses that you use have been added to your name service database.
You should have performed this verification during the Sun Cluster installation. See the planning chapter in the Sun Cluster 3.1 Software Installation Guide for details.
To avoid any failures because of name service lookup, ensure that all of the logical hostnames and shared addresses are present in the /etc/inet/hosts file on all of the cluster nodes. Configure name service mapping in the /etc/nsswitch.conf file on the servers to first check the local files before trying to access NIS, NIS+, or DNS.
Create a failover resource group to hold the network and application resources.
# scrgadm -a -g resource-group [-h nodelist] |
Specifies the name of the resource group. This name can be your choice.
Specifies an optional comma-separated list of physical node names or Sun ONE Directory Server that identify potential masters. The order here determines the order in which the nodes are considered as primary during failover.
Use the -h option to specify the order of the node list. If all of the nodes in the cluster are potential masters, you do not need to use the -h option.
Add network resources to the resource group.
For example, run the following command to add a logical hostname to a resource group.
# scrgadm -a -L -g resource-group -l hostname, …[-n netiflist] |
Specifies that a network resource is being added.
Specifies the name of the resource group.
Specifies a comma-separated list of network resources.
Specifies an optional, comma-separated list that identifies the IP Networking Multipathing groups that are on each node. Each element in netiflist must be in the form of netif@node. netif can be given as an IP Networking Multipathing group name, such as sc_ipmp0. The node can be identified by the node name or node ID, such as sc_ipmp0@1 or sc_ipmp@phys-schost-1.
Sun Cluster does not currently support using the adapter name for netif.
Verify that all of the network resources that you use have been added to your name service database.
You should have performed this verification during the Sun Cluster installation. See the planning chapter in the Sun Cluster 3.1 Software Installation Guide for details.
Run the scswitch command to enable the resource group and bring the resource group online.
# scswitch -Z -g resource-group |
Moves the resource group to the MANAGED state, and brings the resource group online.
Specifies the name of the resource group.
After you configure and activate the network resources, go to Installing and Configuring Sun ONE Directory Server.
