cmmodnet || SG A.11.18.00

[boomerang]

Hello Admins,

Model : ia64 hp server rx6600

Service Guard A.11.18.00 running in HPUX 11.23

We have lan2(PRIMARY) and lan3(STANDBY) configured as HEARTBEAT_IP .

Recently it switched automaticaly from lan2 to lan3(reason need to be checked)

Can I switch back to lan2(PRIMARY) with the below command ?

“cmmodnet –e lan2” can this command be run with cluster and packages up?

What will be the impact if command is executed online(cluster and package up) in the SG version we are having ?

Please suggest

Well it looks like lan2 is still not functioning, otherwise the cluster would detect it and move back... So you need to fix the network problem, then Serviceguard should sort itself out...
