I would like to get some help configuring my compute nodes to use multipath when establishing iscsi connections with a IBM Storwize v3700 storage. <br><br>I have 1 controller, 1 network node and 2 compute nodes. The IBM Storwize driver is configured on controller and volumes can be created and attached to instances running on compute nodes. <br><br>However, my storage has 2 nodes (canisters or controllers) and each one has two 10G interfaces for iscsi use. So, I have four IPs configured as iscsi at storage. But, when I attach a volume to some virtual machine, the compute node uses the first IP of the 'primary' controller (IBM calls this by 'config node'). <br><br>I've read a lot of documentation but I couldn't find certainly what I need to configure neither where I need to put these configuration. <br><br>What I've already read is that this model of storage doesn't answer to iscsi calls with a list of available iscsi IPs, as do some others equipments. So, I need some way to tell nova that I have more than one IP address available, so iscsi commands can connect using not just one IP. <br><br>Making compute nodes connect to 2 iscsi IPs then I can use multipath. I've already configured multipath on compute nodes but it isn't used. <br><br>So:<br><br>- how to configure nova to use multipath?<br>- how to configure nova to make more than one iscsi connection?<br><br>I appreciate ANY help, documentation, configuration examples etc. <br><br>Thanks!<br>:)<br><br clear="all"><div><div class="gmail_signature"><div dir="ltr">- JLC</div></div></div></div>
