We are building out a new 2012 R2 Hyper-V cluster. The old environment is a mix of Cluster Shared Volume drives and LUNs presented just for the a VM itself.
I had planned on presenting everything in the old environment to the new environment and then just using the cluster migration wizard to move VM's over a few at a time.
I ran into a problem when I connected my first host to our SAN today. It is in a group that has over 70 LUN's presented to it. Once I connect to the target the host just cripples. I am not having Memory or CPU issues but Disk IO issues. I noticed that the host now sees all 70 plus LUNs and has tried to bring those disk online as well.
I don't want them online right now. I just need the quorum drive and a few of the newly created LUN's online to finish creating our Cluster so we can start migrations.
Why is the Host trying to bring these drives online? As soon as I click on Devices in the iSCSI initiator the program locks up and doesn't respond.
Is there a way to setup the target but force the OS not to bring any of those disk online? I removed the favorite target, and there are no items listed in the Volume List under Volumes and Devices. However if you go to Disk Manager it shows all 70 plus disk and most of them now show online except for my newly created LUNs which are not initialized yet.
