[Linux-cluster] Downing secondary interface if primary fails?

[gordan bobich net]

Hi,

Say a machine is a part of a cluster. It has eth0 for WAN accessm and eth1 
for SAN/cluster access. Say eth1 fails - is there a way to get eth0 to 
shut down as well, so the machine doesn't appear to be alive and thus get 
traffic routed to it?

Thanks.
