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

gmurison07

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

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

Hi,

Looks absolutely ok.

Thanks!

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.

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.
