Hello,
We've recently acquired a 2 node FAS8020 cluster running Clustered DataONTAP 8.2. We inherited a rather unusual/silly network topology, in which we have two subnets (a publicly routable one and an RFC1918 one for internal use only) running on the same VLAN. In other words, there's no router between these two subnets.
In Linux, we're able to get boxes on the publicly routable subnet to communicate with the internal subnet (10.1.0.0/16) as follows:
route add -net 10.1.0.0 netmask 255.255.0.0 dev eth0
This command tells the Linux box that it can send packets to 10.1.0.0/16 hosts out eth0 without going through an intervening router. However, we've yet to find a way to do this with Cluster DataONTAP. We've played around with routing groups and routes, but we cannot figure out a way to tell Clustered DataONTAP to route through an interface. Does anyone know if this is possible? NetApp has advised us to set up a router between our two subnets. We share NetApp's concern over fail over
We'll set up a router if we can't figure out any other way to make this work.
Thanks
John
In cDOT you have ports and LIFs. You can have multiple LIFs with different addresses (and networks) which share the same port. Just create two LIFs, in each network, and associate with the same port that is physically connected to your VLAN.
