Hi John,

we have a FAS3240, too and the same behavior. I opened a Netapp Case (Case ID: 2002377504):

" During failover the IP address will be assigned to the surviving node, which does not reset. During giveback the filer reboots and this causes the network interface to reset. This is the timeout seen by the customer."

greets

Steffen

Betreff: Fas 3240 failover delay

Hello everybody

I have a Fas3204 HA in two seperate chassis , dataontap version 8.02P3 7mode. Many NFS servers are connected to it via iscsi connections. NFS servers are VMware mashines . VMware version is VSPERE 5. There are 4-5 Vfilers running. When i force a failover from the one controler to other, the NFS clients

have a delay about 30-40 seconds. Is this normal? Can i do something to investigate/tune the failover proccess?

thnks in advance

John
