Isilon node not reachable
I have 1 node in a 3 node cluster that is not reachable via ping or SSH (node 2 and 3 i can ping)
The node has an IP addressed assigned to it and it shows up and healthy, but when i try to ping it i get no reply.
Ran isi networks list ifaces and the configuration looks good.
Any insight on what the problem might be?

You note that the node has an IP address - how are you seeing that? I assume in a status output from another node, there is communication coming over the back end to indicate the node is responsive.
I would start at the external network cables as the simplest starting point.
Then connect a console to the errant node to ensure you get responses from commands.
You can also ssh to node 1 normally - then from there SSH over the back end IP to node 2 and see if you get a response.
If the ping signal is successfully reaching node 2, but not getting a response, then I would suspect a hanging or unresponsive node, so I'd be testing through other ways to access node 2.

If I had to venture a guess I would say that you have a layer-2 issue, meaning the switchports for the node in question are likely up, but on the wrong VLAN.
