Use this procedure to change a private network address or the range of network addresses used or both. To perform this task using the command line, see the cluster (1CL) man page.
Before You Begin
Ensure that remote shell ( rsh (1M) ) or secure shell ( ssh (1) ) access for the root role is enabled to all cluster nodes.
The clnode evacuate command switches over all device groups from the specified node to the next-preferred node. The command also switches all resource groups from the specified node to the next-preferred node.
# clnode evacuate node # cluster shutdown -g0 -y
When run in noncluster mode, the clsetup utility displays the Main Menu for noncluster-mode operations.
The clsetup utility displays the current private network configuration, then asks if you would like to change this configuration.
The clsetup utility displays the default private network IP address, 172.16.0.0, and asks if it is okay to accept this default.
The clsetup utility will prompt for the new private-network IP address.
The clsetup utility displays the default netmask and then asks if it is okay to accept the default netmask.
The default netmask is 255.255.240.0. This default IP address range supports up to 64 nodes, 12 zone clusters, and 10 private networks in the cluster.
When you decline the default netmask, the clsetup utility prompts you for the number of nodes and private networks, and zone clusters that you expect to configure in the cluster.
From these numbers, the clsetup utility calculates two proposed netmasks:
The first netmask is the minimum netmask to support the number of nodes, private networks, and zone clusters that you specified.
The second netmask supports twice the number of nodes, private networks, and zone clusters that you specified, to accommodate possible future growth.
On SPARC based systems, run the following command.
ok boot
On x86 based systems, run the following commands.
When the GRUB menu is displayed, select the appropriate Oracle Solaris entry and press Enter.
# cluster status -t node
