SR failed to complete operation-> LUN not found

Have you tried other iSCSI Targets? I am just wondering how can we help you if this looks like Xen issue.

Hi Pi-L
this is the problem, from this location, I have no other iSCSI Target available, the productiv iSCSI Targets are all in other locations separated in VLANS.
I am trying bto figure out something, to get another Target available. Thought about the same thing yesterday. unfortunately, the Buffalo I am having here for NAS does not do iSCSI, only NFS.
I also thought of this might be an XEN issue, however, have some trouble in fihuring out the real sourc of problems. Both systems are new and have never prouven to be ok.
The XEN works with the NFS Share and the local store, The iSCSI open-e is ready prepared with the 1,8 TB Volume.

try mabye something like:
iqn.2011-11.dss.target0 or iqn.2011-11.dss:target0 as a name

If you still cant tell what is malfunctioning the ultimate test would be connect to iSCSI target for example from Windows initiator, if it works that would mean the rest is up to XEN configuration. Have you tried that?

Hi Pi-L
I thought of that. I will get me a W2k8R2 server this afternoon to check the connection to the open-e.
I was curious to do so in the first time, since the w2k8 would be a vm on that XEN SRV. I am getting me a W2k8 labserver put on another xen, which has good iscsi plugs to a standard open-e V6.

Keep you postetd.

Hi Pi-L
looks like it is a Problem of the installed Xen.
I used another XENSERVER, which is just for test and lab pourpose, but basicaly not in the same IP segmnet. Putting it into an IP range which could be reached via WAN, Icould plug the open-e dss6-lite.

Now I need to find out whats wrong with this XEN Server, since this is the same installation build as the one which could do the plugging
Thanks for your help.

If it is not in production yet always best way to start is to clean everything and install again..

Hi
found the solution:
I had an USB Device plugged on the Xenserver to import the vm files. Even though, it was no longer mounted, this IOMEGA HD blocked the cach of the scsiid which caused the plug from the iscsi volume to fail.
