Default private host names are assigned during initial cluster installation. The default private hostname takes the form clusternode< nodeid>-priv, for example: clusternode3-priv. Change a private hostname only if the name is already in use in the domain.
Caution - Do not attempt to assign IP addresses to new private host names. The clustering software assigns them.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.
phys-schost# clresource disable resource[,...]
Include the following in the applications you disable.
HA-DNS and HA-NFS services, if configured
Any application that has been custom-configured to use the private hostname
Any application that is being used by clients over the private interconnect
For information about using the clresource command, see the clresource (1CL) man page and the Oracle Solaris Cluster Data Services Planning and Administration Guide .
Use the svcadm command to shut down the NTP daemon. See the svcadm (1M) man page for more information about the NTP daemon.
phys-schost# svcadm disable ntp
Run the utility from only one of the nodes in the cluster. for more information, see the clsetup (1CL) man page.
You can also run the clnode command instead of the clsetup utility to change the private hostname. In the example below, the cluster node name is pred1. After you run the clnode command below, go to Step 6.
phys-schost# /usr/cluster/bin/clnode set -p privatehostname=New-private-nodename pred1
Answer the questions when prompted. You are asked the name of the node whose private hostname you are changing (clusternode< nodeid>-priv), and the new private hostname.
Perform this step on each node in the cluster. Flushing prevents the cluster applications and data services from trying to access the old private hostname.
phys-schost# nscd -i hosts
If you changed a private hostname in your NTP configuration file (/etc/inet/ntp.conf) and you have peer host entries or a pointer to the include file for the peer hosts in your NTP configuration file (/etc/inet/ntp.conf.include), update the file on each node. If you changed a private hostname in your NTP include file, update the /etc/inet/ntp.conf.sc file on each node.
If you perform this step at installation, also remember to remove names for nodes that are configured. Typically, the ntp.conf.sc file is identical on each cluster node.
Perform this step on each node of the cluster.
Use the svcadm command to restart the NTP daemon.
# svcadm enable svc:network/ntp:default
phys-schost# clresource enable resource[,...]
For information about using the clresourcecommand, see the clresource (1CL) man page and the Oracle Solaris Cluster Data Services Planning and Administration Guide .
The following example changes the private hostname from clusternode2-priv to clusternode4-priv, on node phys-schost-2. Perform this action on each node.
