Adding an additional VLAN to FAS 2240 (Ontap 8.2.5 7-mode)

Based on research here and documentation I have a plan from adding a VLAN to our 2-node HA cluster.

I just wanted a sanity check if possible. I have changed some values to protect the innocent.

Add an entry to /etc/hosts:

172.201.10.15 node-a-vif1-201

Add an entries to /etc/rc:

vlan create vif1 201

ifconfig vif1-201 `hostname`-vif1-201 netmask 255.255.255.0 partner vif1-201 mtusize 9000 nfo

Full config:
=============================
etc/hosts
=============================
127.0.0.1 localhost localhost-stack
127.0.10.1 localhost-10 localhost-bsd
127.0.20.1 localhost-20 localhost-sk
192.196.0.64 node-a storage01-a-vif1-1
172.22.1.10 node-a-vif1-2
172.201.10.15 node-a-vif1-201
# 0.0.0.0 node-a-e0M
# 0.0.0.0 storage01-a-e0P
=============================
/etc/rc

Since you are adding a new network to your controllers you may want to review the routed on entry in your /etc/rc file. This command enables a routing daemon which you (and or your network engineers) may not want running in your environment now storage is connecting to multiple networks.

Yeah...to be safe place the interface to be routed first, then the routed line then the remaining ifconfig lines.

Thanks all, this was originally setup by a VAR so I am not sure why the routing daemon was enable since have a small network with no dynamic routing in place.
