Only time I have seen stuff like that is when it's in multimode on the filer, and etherchannel is not properly enabled on the switch.

I am having a great deal of difficulty getting my filer's 10g interfaces connected to a pair of 3750E switches I am trying to use for my storage network's backbone. I can inconsistently ping other objects on the network (there really is nothing there yet, we are just getting started, but I do have a host and an RLM card just for troubleshooting purposes), but they cannot ping each other. From a remote host (172.1.2.5) I can ping everything but array1. If I bring down either of the two stacked switches (which brings down one port of each VIF member pairs) everything works.
array01> ping 172.1.0.1
172.1.0.1 is alive
array01> ping 172.1.0.2
array01> ping 172.1.0.4
ping: wrote 172.1.0.4 64 chars, error=Host is down
ping: wrote 172.1.0.4 64 chars, error=Host is down
array01> Thu May 15 13:28:33 EDT [gvr-array01: nis_worker_0:info]: Local NIS group update successful.
array01> ping 172.1.2.5
172.1.2.5 is alive
array02> ping 172.1.0.1
array02> ping 172.1.0.4
172.1.0.4 is alive
array02> ping 172.1.0.4
172.1.0.4 is alive
array02> ping 172.1.0.250

array02> ping 172.1.2.5
no answer from 172.1.2.5
