Windows 2008 iSCSI Target Connection Problem

[fusspils]

I have a test Windows 2008R2 Server running the iSCSI software target. The virtual disk etc has been setup on this server and other Win 2k8 machines can connect to it with no problems.
I am trying to add an iSCSI target in the Proxmox admin gui to this Win 2k8 server but it always fails with the error "Found no unused targets" when I try to connect. I have verified that there are unused targets on the Win2k8 machine. Any help/pointers would be great. Thanks.

Please can you post your storage configuration (/etc/pve/storage.cfg)

Hi Dietmar,

Thanks for your reply. I dont seem to have the file that you are asking for in that location? Just cluster.cfg and a few ssl key files?

Does it detect any iSCSI target when you scan the portal?

 

[fusspils]

I'm not sure if it detects it or not, it just give me a pop up error saying "found no unused targets" when I hit the scan link. It works fine from other Windows Servers so I'm wondering if this is some sort of config thing that I'm missing in Proxmox?

Is the host allowed to access the target? - please check the permissions on the server.

As far as I know the host should be allowed to access the server. The secondary Win2k8 machine connects without any authentications and these servers are not part of a domain. If I enable CHAP authentication on the Microsoft iSCSI software target, where do I enter these credentials on the Proxmox server?

We do not support CHAP - you need to enable access based on the IP address.

Thanks again for you reply Dietmar, I have now connected the Proxmox Server to the Win2k8 Server via iSCSI. I had to go into the properties of the iSCSI targets on the Win2k8 box and select the iSCSI initiators tab then enter the IQN of the Proxmox server. After doing this and scanning in the Proxmox GUI it detected the virtual disk. Next problem is how do I initialize/format the disk that shows up in the Proxmox storage list. It states that its connected, active etc but the "used" and "capacity" is listed as n/a. Any extra help/pointers would be great and thanks again for the support

Hi,
if the iscsi-disk is empty, create an volume group on the disk and then define this volumegroup in the storage-gui as lvm-storage.
e.g.: (be sure to use the right device)

pvcreate /dev/sdb
vgcreate -s 4M iscsi_vg /dev/sdb

You can also use an partition with type 8e (e.g. /dev/sdb1)
