Adding vip resource (11gR2 Linux)

Enviroment: Oracle Linux 5 update 5 64bit, Oracle RAC 11gR2

While installing  RDBMS software on Oracle 11gR2 cluster following error was encountered.



as error showed that vip resource is not existing for one of the node, it was added as below.
1-  First check the nodeapps status

[root@rac2 bin]# ./srvctl status nodeapps
VIP rac1-vip is enabled
VIP rac1-vip is running on node: rac1
Network is enabled
Network is running on node: rac1
Network is running on node: rac2
GSD is disabled
GSD is not running on node: rac1
GSD is not running on node: rac2
ONS is enabled
ONS daemon is running on node: rac1
ONS daemon is running on node: rac2
eONS is enabled
eONS daemon is running on node: rac1
eONS daemon is running on node: rac2

You observe that no rac2-vip resource is not running.

2- Further confirm by checking the config and ping
[root@rac2 bin]# ./srvctl config nodeapps -a
VIP exists.:rac1
VIP exists.: /rac1-vip/132.35.21.187/255.255.255.0/eth0

[root@rac2 bin]# ping rac2-vip
PING rac2-vip.localdomain (132.35.21.188) 56(84) bytes of data.

, pipe 3


3- try to add the resource
[root@rac2 bin]# ./srvctl add vip -n rac2 -A rac2-vip/255.255.255.0/eth0 -k 2
PRCN-2049 : The network attributes specified (network number: 2, subnet: 132.35.21.0, adapters: eth0) conflict with an already registered network (network number: 1, subnet: 132.35.21.0, adapters: eth0)
you get the error for network attributes so change and then retry.
[root@rac2 bin]# ./srvctl add vip -n rac2 -A rac2-vip/255.255.255.0/eth0 -k 1
[root@rac2 bin]#

4- Check that resource is added or not
[root@rac2 bin]# ./crs_stat -t

it is added but not ONLINE

5- start the nodeapps
[root@rac2 bin]# ./srvctl start nodeapps

6- Check the resource again
[root@rac2 bin]# ./crs_stat -t

CRS-2529: Unable to act on 'ora.rac2.vip' because that would require stopping or relocating 'ora.LISTENER.lsnr', but the force option was not specified

[root@rac2 bin]# ./srvctl stop vip -n rac2 -f
Remove vip
[root@rac2 bin]# ./srvctl remove vip -i rac2
Please confirm that you intend to remove the VIPs rac2 (y/[n]) y

add vip again
[root@rac2 bin]# ./srvctl add vip -n rac2 -A rac2-vip/255.255.255.0/eth0 -k 1
[root@rac2 bin]#
check again
[root@rac2 bin]# ./srvctl config vip -n rac2
