clue about this?:

Subject: Oracle 10gR2 RAC VIP Question

Hi,
I have a 2 node 10gR2 (10.2.0.2) Installation running on HP-UX (PA-RISC) 64 
Bit, 11.23. HP Serviceguard Extensions for RAC (11.17) is also installed.
.
Due to maintenance both nodes were brought down. One they were brought up, I 
noticed that the vip for one node - node2, was running on interface lan0:2. 
lan0 is our public interface. Now typically, the vip runs on lan0:1. When a 
node is evicted from the cluster, the vip of the evicted node gets relocated 
from lan0:1 on the evicted node to lan0:2 on the surviving node. 
My question basically is, does it matter which logical interface 
(:1,:2,:3,:4,etc) the vip runs on for any node - be it the evicted node, or the 
surviving (master) node. Essentially the mapping for the vip is defined in the 
OCR and the /etc/hosts file. There is no mention of whether this should run
 on :1,:2,:3,:4,etc - only that it should be on the public interface - lan0 - 
which it is.
A look into the ocr file, and this is all i can find:
.
[SYSTEM.css.interfaces.global.lan0.172|d25|d3|d0.1]
.
Not sure what d0.1 means?, the first three segments are those for the public 
network. .1 = :1 = lan0:1 ??
That said, whenever I have seen a relocation of the vip take place it goes to 
lan0:2 - However as mentioned earlier, lan0:2 is already in use by one of the 
nodes, if a relocation to this node were to take place would the the vip come 
up here as lan0:3 - unfortunately I can't test this out yet, but was wondering 
if anyone had an idea on this?
Thanks

Naqi
