11gR2 Add VIP to Node

I'm just curious on Forums.

PRKO-2165 : VIP does not exist on node(s) : linux2

I'd like to know Add VIP to a node idea. So, Tested It.

Virtual IP = 192.168.254.92

/etc/hosts file:
192.168.254.92 RHEL5-TEST-VIP

# ./srvctl status nodeapps
Network is enabled
Network is running on node: rhel5-test
GSD is disabled
GSD is not running on node: rhel5-test
ONS is enabled
ONS daemon is running on node: rhel5-test
eONS is enabled
eONS daemon is running on node: rhel5-test
PRKO-2165 : VIP does not exist on node(s) : rhel5-test

# ./srvctl start nodeapps
PRKO-2421 : Network resource is already started on node(s): rhel5-test
PRKO-2439 : VIP does not exist.
PRKO-2422 : ONS is already started on node(s): rhel5-test
PRKO-2423 : eONS is already started on node(s): rhel5-test

$ ./crsstat vip

Try to add VIP on my node.

srvctl add vip -n node_name -A {name|ip}/netmask[/if1[if2|...]]
   [-k network_number] [-v]

# ./srvctl add vip -n rhel5-test -A 192.168.254.92/255.255.255.0/eth0 -k 2
PRCN-2049 : The network attributes specified (network number: 2, subnet: 192.168.254.0, adapters: eth0) conflict with an already registered network (network number: 1, subnet: 192.168.254.0, adapters: eth0)

So, changed network_number:

# ./srvctl add vip -n rhel5-test -A 192.168.254.92/255.255.255.0/eth0 -k 1

Check again & again.

VIP exists.:rhel5-test
VIP exists.: /192.168.254.92/192.168.254.92/255.255.255.0/eth0

That's a example to fun -)

By the way, we should add vip by name.
From /etc/hosts file:
192.168.254.92 RHEL5-TEST-VIP

# ./srvctl stop vip -n rhel5-test -f
# ./srvctl remove vip -i rhel5-test
Please confirm that you intend to remove the VIPs rhel5-test (y/[n]) y

Check:

$ ./crsstat vip
HA Resource Target State (Host)

ora.scan1.vip ONLINE ONLINE on rhel5-test

start add VIP:

# ./srvctl add vip -n rhel5-test -A rhel5-test-vip/255.255.255.0/eth0 -k 1
# ./srvctl config vip -n rhel5-test
VIP exists.:rhel5-test
VIP exists.: /rhel5-test-vip/192.168.254.92/255.255.255.0/eth0

Check:

$ ./crsstat vip

ora.rhel5-test.vip OFFLINE OFFLINE
ora.scan1.vip ONLINE ONLINE on rhel5-test

then start...

# ./srvctl start vip -n rhel5-test
$ ./crsstat vip
