LIF Failover conditions

steven_langdale

Hello

 

I'm trying to confirm the conditions that will initiate a LIF failover.  Aside from a whole node going down, will a LIF only failover if there is a link loss?

 

If that's the case, is there any other options I can employ to protect against the upstream switch failing but NOT taking a port offline?  I can't use LACP across two switches in this environmment.

 

Thanks

 

Steven

I believe this is what you looking for Scenarios that cause a LIF failover.

If you have multiple core and switch redudency, upstream switch failing should not be a problem in your network.

 

Ontap is not designed to handle such failure. that should be handled in your network design.

In a NAS environment, netapp controller is not aware or keeping track of the client status until client request reach netapp.

 

Let the controller do what it disigned/suppose to do rather than trying to fix everything with it.

 

Here is some failover policy you can configure on your LIFs..

And I can gurantee none of them handle an upstream switch failure.

Thanks for that Robin,  and I'm currently looking at the network design.

 

Can you confirm that LIF failover will only occure with a loss of link?
