Replace the Oracle cluster NIC (changing a network Interface)

Assume that the NIC name is changed before and after. IP, gateway, subnet mask is not changed, the cluster level is not allowed to do additional operations.

After you replace the NIC, use the new NIC name

1. Ensure that all cluster nodes are active
Olsnodes-s

[Email protected] ~]$ olsnodes-s
Vmrac1 Active
Vmrac2 Active

2. Ensure that the new replacement NIC is already configured on the server
$/sbin/ifconfig..

3. Add the new NIC to the cluster
Oifcfg Setif-global If_name/subnet:cluster_interconnect

Oifcfg Setif-global "Eth*/192.168.0.0:cluster_interconnect

4, after the completion of the new NIC joined. Remove the previous configuration information
Oifcfg Delif-global if_name/subnet
For example:
$ oifcfg Delif-global eth1/10.10.0.0

5. Verify the current configuration information:
Oifcfg getif

For example:
$ oifcfg Getif
Eth2 10.220.52.0 Global Cluster_interconnect
Eth0 10.220.16.0 Global Public

6. Restart the cluster
# Crsctl Stop CRS

7, OS level delete network card
$ ifconfig Down

8. Restart the cluster
# Crsctl Start CRS

Let's say we use cluster_interconnects to make the corresponding changes.
