Linux iscsi multipath---how to bind the NIC's to the software initiator ?

Question

Hello, I have a Linux server with two NIC's to connect a VNX storage via iscsi software initiator. 1. How to setup the IP's of the NIC's and the iscsi ports on the storage SP's ?  Do they should be in the same subnet ? 2. How to connect the network switches, is the following correct ?  NIC1 on the server------Switch1------SPA NIC2 on the server------Switch2------SPB 3. Can two ports on one storage SP connect to different switches(crosslink) as following ? NIC1 on the server------Switch1------Port1 on SPA                                           |                                           |_______Port1 on SPB| NIC2 on the server------Switch2------Port2 on SPA                                           |                                           |_______Port2 on SPB| 4. how to bind the NIC's to the software initiator ? Very very thanks!

You can get detailed information about connecting a new server to an existing array. Please go to mydocs.emc.com, select VNX Series. the near the bottom select Attache a Server.

Follow the steps to get a configuration guide.

With iSCSI you also want to take a look at KB article 463477 for a list of articles pertaining to iSCSI. Also see KB 470899 for more specific configuration information.

Hi,

1. You need a subnet per port pair. e.g. port 0's one subnet, port 1 another subnet and etc.

=> So, A0 and B0 same subnet, A1 and B1 another subnet.

2. Not correct, Follow instruction above.

3. Yes, that looks good.

4. It will depend on your Linux version, but the basics will be to setup a nic to each subnet and use iqn names to the target,

look at the doc from Glen. You should look at the EMC host config guide.
