not sure what version you are on, but our fastpath comment reminded me of a entry in the Clustered Data ONTAPĀ® 8.2.1 Release Notes: ---------- Disabling fast path in some networking environments Fast path is enabled by default in all nodes in the cluster. However, you might have to disable fast path in certain environments in which fast path does not function optimally. About this task IP fast path is a mechanism that uses the network interface of an inbound request to send the response quickly by bypassing a routing table lookup. Fast path is enabled by default for all TCP and NFS over UDP connections. You might have to disable fast path if you are working in configurations of Cisco vPC, HP NIC teaming, or asymmetric routing environments. Steps 1. From the nodeshell, enter the following command: options nodescope.reenabledoptions ip.fastpath 2. To disable fast path, enter the following command: options ip.fastpath.enable off For more information, see the bug ID 494396 in Bugs Online on the NetApp Support Site at support.netapp.com/NOW/cgi-bin/bol. ---------- IP Fast path feature is incompatible with some networking environments http://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=494396 ********************************************************** Electronic Mail is not secure, may not be read every day, and should not be used for urgent or sensitive issues
