Solution: Native: listNetInterfaces: [3] When Oracle 10201 RAC is root

I. Problem

10201 when RAC is installed on OEL5, the following error is reported for the root 2nd nodes:
[Root @ o10n2 install] #/oracle/product/10.2.0/crs/root. sh

Running the graphical vipca will also report:

II. Solution

[Root @ o10n2 bin] #./oifcfg iflist
Eth0 192.168.150.0
Eth1 172.16146.0
[Root @ o10n2 bin] #./oifcfg setif-global eth0/192.168.150.0: public
[Root @ o10n2 bin] #./oifcfg setif-global eth1/171_146.0: cluster_interconnect
[Root @ o10n2 bin] #./oifcfg iflist
Eth0 192.168.150.0
Eth1 172.16146.0
[Root @ o10n2 bin] #./oifcfg getif
Eth0 192.168.150.0 global public
Eth1 172.16146.0 global cluster_interconnect

The graphical vipca can be opened. Run rootdelete. sh and then run root. sh. The above error is missing.
