This issue has been solved. See solution.


running a two nodes VCS 5.0MP3 on RHEL5.3, each node as two NIC configured with bonding. The bonding interfaces run perfectly in fail-over mode.
The NIC agent is monitoring a bonding interface.
When both interface are unplugged, the NIC agent never faults the resource...

Normal, not normal ?

Hello Herve,

Could you please tell more about how you have configured resource ?

does NIC resource lie in a service group which holds some more resources OR  NIC resource is parallel & just contain NIC resource ?

Would be great if you can paste file from cluster...

 Hi Herve,

This is a known issue in VCS if certain attributes are defined in your file.

If you could paste the contents of NIC resource it would be more clear.

If you are using configuration like following..then Remove the NetworkHosts attribute and try again.

NIC NIC_bond0 (
Device = bond0
Mii = 0
NetworkHosts = { "IP_ADDRESS_OF_ROUTER" }

I would suggest that open a support case with Symantec.

many thanks.
I put the NICs in the ClusterGroup.
I will try after removing NetworkHosts and tell you more...

I won't open a case, because it is my sandbox !
