    I am setting up a print cluster on a pair of Windows 2008 server using iSCSI. My question is do both the quroum disk and the print spooler disk have to be online on both machines at the same time?

    Thanks

    You will want two seperate LUN's.  One for the Spooler resource, and another for the Witness disk.  The disks will only be accessible by 1 node at a time, and they disks don't need to be owned by the same node... it doesn't really matter which one owns it (for the most part).

    Thanks!

    Hi!

    When you connect the LUN the first time to the nodes, they appear offline on both of them. At this time they are not part of the cluster. You can now take the disks online on one node and create a filesystem on them. In case you have already created the cluster you can now add the disks to the cluster (failover cluster mmc, storage, add storage). Now they are part of the cluster and can be moved from one node to the other, but they are only online on one node at the time.

    If you have any more questions, just ask...

    Hope that helps,
    Andreas

    Thanks Elden,

    I do have 2 LUN setup, one for the spooler and one for the witness. When I attached the LUNs to both servers, they are offline. My questions is do I have to make them both online for both servers, or do I just make them online for one server, and only make them online for the other server if the failover occur.

    I would recoomend you to use as iSCSI target only product from Starwind. Recently I`ve made cluster on iSCSI and in for failover I used RAID-0 based on this iSCSI - really great option!
