I was hitting this problem as far bac as in 10.1.0.3 and at that time
spent countless hours for Oracle support and development trying to
figure out the best solution. Removing dependency wasn't recommended
by support even though development was quite sure it should work. And
it did work when we tested it.
The best workaround recommended was to set check interval to 0 for VIP
resources that ultimately disables checking completely. Thus, public
network failures are not affecting VIP resource status but any manual
manipulation of VIP resources (stopping) would be obviously reflected
on ASM and databases.
I quickly tried it in 10.2.0.3 and it seems to be working OK but do
you own homework.
I posted about it some time ago if interested -

Hi,
Currently running 10.2.0.2 RAC with ASM. I have 2 questions (hoping someone
has experienced this):
1. A public network failure results in a relocation of the vip. The
relocation of the vip results in the corresponding asm instance shutting
down, which in turn stops the rdbms instance associated with it. There is a
workaround in metalink, that discusses how to remove this dependency (for
releases under 10.2.0.3).
I was wondering if anyone has used this workaround? I also wanted to know if
once this dependency has been removed, and there is a public network failure
- once this (public network failure) is resolved does the vip automatically
relocate back to its original node or does this still need to be done
manually. Apparently in 10.2.0.3 once the public network issue is fixed the
vip will automatically relocate back - since asm no longer has a dependency
it and the rdbms instance will not need to be started.
2. Can or Has anyone tested public network failures in 10.2.0.3 - does it
work as advertised ?
Thanks
