Like the title says I'm trying to setup iStorage Server to use as the back end storage for all of my hyper-v virtual machines.

Running Server 2008 Enterprise r2 as the Hyper-V Host. Dual Hex Core 2.2ghz Processors, 32gb Ram, (6) 250GB Hard Drives in raid 6, Gigabit Ethernet.

The End goal is to run 4 Server 2008 Images with light usage, 2 Windows XP Images with mid to light usage, and one SuSe image with fairly heavy usage.

My iStorage Server is an HP Ml350 g5 2.5ghz Quad Core, 4gb RAM, (4) 2tb Hard Drives in RAID 5 for Data, (2) 512gb Hard Drives for the OS.
My iscsi target is configured to use the physical disk with exclusive access, I've enabled chap, created a group and granted the chap user full access.

So with that out of the way.
When I try to migrate any of my Hyper-V VMs over to the iStorage server the copy goes fine, but when I try to reattach and start the server it hangs right away and causes my Host Server to become unresponsive.


Any suggestions?

After a few days test, unfortunately we couldn't reproduce the problem.
You created a physical disk target and export (via iSCSI) this device to your hyper-v server, and you create virtual machines or copy virtual machines files to this iSCSI disk, but these virtual machines can't be started.
Is my understand right?
Do you have any extra settings?
Can you please tell me what os (which version of windows and 32bit or 64bit) running the iStorage Server?

My istorage server is running Windows Server 2008 64bit. The hardware is an HP ML350 G6.
Basically I just drag a vhd over to the istorage server drive and then edit the settings for the virtual machine to point to the vhd I just copied over. This works when I try it in my test environment just moving between local physical disks it works fine. So I've got to assume i'm doing something wrong with the iStorage server product. Is there some kind of logfile I can attach to this to show you all of my iStorage server settings?
