2 node HA cluster with iSCSI volume

[bsinha]

Hi,

I was wondering whether I can create a 2 node failover cluster with iSCSI volume, where a VM will reside in node1. The VMdisk of that VM will be configured in that iSCSI storage. The iSCSI storage will also be shared with another node. (Say node2).

Objective:

1) If node 1 goes down for some reason, can the hosted VM be migrated into node2 automatically by configuring HA or any other method?

Please note that, 3-node cluster is not an option here. Just seeking, if the same can be achieved with a 2 node scenario.

With two nodes, the remaining node does not have quorum (and it won't work). Lots of threads on this forum about problems with two-node clusters. You need at least one additional vote (which can be a QDevice instead of a third node).

What is QDevice? How can I configure it?

There are so called Hyperlinks in @leesteken 's Post...!
