"ifconfig lan901:802 down" will remove the virtual ip online ... BUt ...

"without bringing the RAC down !!!".... we can't say anything... as you said its oracle RAC-VIP , there is a chance the rac node can went down.

My question is that, does your application going to effect even one rac node went down ??? i feel there won't be any problem for your application...

Pls check with DBA team

the above excerpts are from the node1 netstat -inv
i did an ifconfig lan901:802 down that is having IP address 10.29.8.48 on node1.

but this is vip of 4th node of the 4 node CRS cluster.


still as this is down or up when i do ssh to the IP 10.29.8.48 this is taking me to the 1st node whereas this should take me to the 4th node as this is ora-vip of node4.

i tried doing an arp -d 10.29.8.48 on 1st node but and putting new entry of arp for node4 like this on node1 like
arp -s 10.29.8.48

but still the same thing.

ssh 10.29.8.48 takes me to node1 from node1 whether this should take me to node4 when executed forrm node1.

Does we missing somthing from oracle side ?
How lan901:802 got configured on node1 ?
is it from system side or database side ?

Can we check these points ..
