strange route issue in powerha 5.4?
hi all
we upgraded hacmp(powerha) from 5.2 to 5.4 recently .
during the failover testing, we found a strange network issue. after standby node took service ip address (172.15.100.8) online at standby NIC, we were able to log in the standby node by telnet 172.15.100.8 which stays at standby node standyb NIC.
when we tried to run ping or traceroute to a ip address outside of of our network, for example google.com or ibm.com, the NIC that holds service ip address were not able to send any packet out at all.
instead, the primay NIC that holds boot address of standby node (172.15.103.79) will take in place and send the ping packet out or traceroute to out side of world.
on the other hand, any testing within our intranet acted normal. we checked dns server and routing table of standby node and gateway setup, they were all good.
the follwoing info is the routing configuration from standby node.

as you may see, the default routing is set up for en4 (the primay NIC that holds boot ip address). is it possible that we manally set up a route entry to let en5 ( the standby NIC that will holds the service ip address when failover) go out side as well like this?
