HACMP with VIO, service IP failover
Would anyone please kindly help to solve this problem...
An LPAR with the below network configuration. ent0 and ent1 are logical lan (virtual ethernet) from VIO SEA.
en0
1.2.3.4 <- boot ip
192.168.1.1 <- persistent ip
192.168.1.10 <- service ip
en1
11.22.33.44 <- boot ip
When I unplug the en0 cable (i.e. unplug the corresponding VIO ethernet cable), persistent and service will not failover to en1.
I tried the case for dedicated machine, when en0 is unplugged, in error report it will show a failure of ethernet, and the persistent and service IP will failover to en1. This will not happen at VIO LPAR since it is logical LAN and it will not detect a failure.
I found a solution from IBM to add !REQD <source IP> <destination IP> in the netmon.cf file, but not successful. I also added the IPs for the variable ping_client_list in clrginfo.rc file, but still failed.
Please kindly help how to make the LPAR know there is a failure in adapter, and will failover the persistent and service IP to the other interface.
Thank you very much!!

Hello All,
Here is a snipet from our cluster.log, I was wondering if anyone could shed some light on what may have caused the failover.
The first two lines indicate a possible memory issue which I am currently looking into.

Hi All,
How do I failover on the ip load balancer (back and forth)? It involves first to load a new config on the passive ip. If success, load the new config on the ip active (which is now passive).
Any idea, please.
