looking for a rule

Hi,

unfortunately we have only one central switch for our Heartbeat Cluster.

m1 and m2 have a rule for ping to the gateway.

If the switch must be rebootet - for example for an update - the cluster
makes a
failover, even if it is not necessary.

- md 1 has the resources, md 2 is the DC
- central switch goes down
----> failover....

How can I forbid this special failover?

Greetings

Jochen

Perhaps it makes more sense to have the delay parameter of the pingd tuned?
