Configuring MultiPrivNIC and private IP addresses manually

Perform the steps in the following procedure to configure MultiPrivNIC and private IP addresses for Oracle Clusterware/Grid Infrastructure and UDP IPC manually. Configure the MultiPrivNIC resource in the VCS group where you have configured the OCR and voting disk resources.

Make sure that the number of links are the same for every node. For example, in the following configuration, if the net1 and net2 links fail, the MultiPrivNIC agent fails over the IP addresses to the net3 link on sys1; On nebula, the absence of a third link results in the agent failing over the link to net1, which is already down. This results in loss of communication between the nodes and causes Oracle Clusterware/Grid Infrastructure to reboot the cluster.

MultiPrivNIC multi_priv (
										Critical = 0
										Device@sys1 = {net1 = 0, net2 = 1, 
																											net3 = 2}	
										Device@sys2 = {net1 = 0, net2 = 1}	
										Address@sys1 = {"192.168.12.1" = 0,
																												"192.168.2.1" = 1}
										Address@sys2 = {"192.168.12.2" = 0,
																												"192.168.2.2" = 1}
										NetMask = "255.255.255.0"
										)

Note:

Avoid configurations where the number of links differ between the nodes.

The sample procedure creates the MultiPrivNIC resource in the cvm group. The MultiPrivNIC agent plumbs the IP addresses to the appropriate network interfaces.

To configure the private IP address and MultiPrivNIC manually

Log in as the root user on one of the nodes in the cluster.
Change the cluster configuration to read-write mode:
```
# haconf -makerw
```
Create the MultiPrivNIC resource and add the resource to the same group in which you plan to configure the cssd resource:
```
# hares -add multipriv_resname MultiPrivNIC cvm_grpname
```

Modify the MultiPrivNIC resource:

# hares -modify multipriv_resname Critical 0
# hares -local multipriv_resname Device
# hares -local multipriv_resname Address
# hares -modify multipriv_resname \
Device -add nic1_node1 0 -sys node_name1
# hares -modify multipriv_resname \
Device -add nic2_node1 1 -sys node_name1
# hares -modify multipriv_resname \
Address -add multipriv_ip1_node1 0 -sys node_name1
# hares -modify multipriv_resname \
Address -add multipriv_ip2_node1 1 -sys node_name1
# hares -modify multipriv_resname \
Device -add nic1_node2 0 -sys node_name2
# hares -modify multipriv_resname \
Device -add nic2_node2 1 -sys node_name2
# hares -modify multipriv_resname \
Address -add multipriv_ip1_node2 0 -sys node_name2
# hares -modify multipriv_resname \
Address -add multipriv_ip2_node2 1 -sys node_name2
# hares -modify multipriv_resname \
NetMask netmask_ip
# hares -modify multipriv_resname Enabled 1

Change the cluster configuration to read-only mode:
```
# haconf -dump -makero
```
