Re: iSCSI Initiator
Just to be sure, this means 2 IP adresses on the 2 NICs, and on the SAN side 2 times the server registered with 2 MAC adresses?

Re: iSCSI Initiator
Here is a document I created to setup the HP DSM MPIO correctly.

Re: iSCSI Initiator
Hi,
Thanks for that, looks good.
However it does not mention the configuration of the NICs. Do you configure them with NIC teaming or 2 seperate IP addresses?
Because this has impact on the configuration on CMC side...
Kr,
Bart

Re: iSCSI Initiator
for MPIO you are doing different IP addresses for each NIC on the server.
EG. if you have 10.0.0.10 as your VIP (and 10.0.0.11 and 10.0.0.12 as VSAs with 10.0.0.11 as the coordinating memeber), and you have two NICs on your server (say 10.0.0.21 and 10.0.0.22), you would connect with the iSCSI initiator using the document for MPIO (and DSM if you can) specifying one source IP to the VIP address and then repeat the same setup for the 2nd NIC.
For example, using MPIO+HPDSM on windows and w/ a 2-node cluster with one server connecting with two NICs, you should see 2 connections to the coordinating node and 4 DSM connections (one for each server NIC to each VSA NIC. When setup with the HPDSM, you only need to make the MPIO connection to the VIP and let the HPDSM take care of the rest of the connections.
You can tell if it is setup correctly by going to the iSCSI sessions tab in CSM of the volume you are configuring. The gateway connection is the VSA IP address and the initiator IP is the IP of the NICs on the server, so in my example above you should see a connection from 10.0.0.21 to 10.0.0.11, one from 10.0.0.22 to 10.0.0.11, and DSM connections of 10.0.0.21 to 10.0.0.11, 10.0.0.21 to 10.0.0.12, 10.0.0.22 to 10.0.0.11, and 10.0.0.22 to 10.0.0.12.
