Windows 2008 R2 cluster Issue with Quorum drive to a new drive on SAN migration

Check out these two links.  Everything should work… but it doesn’t always.

Shutdown the cluster

– Disconnect the iSCSI connections

– Move the LUNS on the storage side.

– Offline the old LUNS

– Connect a node to the new storage, check disks appear in disk management as ‘reserved’

– Start the cluster, make sure everything is OK then apply to other nodes.

I added a shutdown of one of the nodes in one of the following steps.

  1. From cluster manager,
  2. right click on the cluster
  3. go to More Actions,
  4. select Configure cluster Quorum Settings.
  5. Change from Node and Disk Majority and switch to only Node Majority.
  6. Once that is complete, disconnect the old LUN from the cluster.
  7. Add the new LUN to the cluster
  8. Go back to quorum configuration and switch back to node and disk majority.


The cluster software writes a disk signature to each drive (LUN) and that is how it keeps track of them.  If you preserve the complete contents of the LUNs, it should not have any issues recognizing them on a different IQN.

iSCSI configuration in a cluster

Configuring the Microsoft iSCSI target software for use in a cluster


Now that Starwind has stopped offering a free, limited version of their iSCSI target software you might be looking for an alternative for your labs. Microsoft has recently made their iSCSI target software available as part of the Windows Storage Server 2008 R2 download on Tech-Net and MSDN. It is not for use in production and has some of its own licensing restrictions, but it works fine and it is free for Tech-Net and MSDN subscribers.

I recorded some really quick and dirty videos that aim to show you how to configure the iSCSI target and iSCSI initiator software in under 7 minutes. At the end, you will have a shared disk array ready to start your shared storage cluster. Hopefully when I get some more time I’ll actually write these steps out, but in a pinch this will give you the general idea of what needs to be done. There are plenty of other features, but for a lab environment this will do the trick. – configuring the iSCSI target software and iSCSI initiator on the client – configuring the iSCSI initiator….continued
