Hello tech-guys
we have a "just another hang" problem.
I am going to build a 4 node hyper-v failover cluster. At the moment we have two nodes.
Node 1 & Node 2 Windows Server 2012 R2 Datacenter Eng - Networks:
1. Live-Mig, 2. Management, 3. Cluster, 4. CSV,5. SAN1,6. SAN2 (SAN 1 + 2 = MPIO)
Our SAN Server is installed with OPEN-E DSS 7.
From the beginning till now i set up 6 CSV Volume (CSV01, CSV07 to CSV11). Everything works fine. Clustervalidation shows no errors, migration works... fine!
Now - I will add another CSV Volume (CSV02), connect mpio iscsi and try test as "local" volume F:\. Works fine, copy with 850 MB/s. But then I try to add these volume to failovercluster and to CSV. At the point i`ve added the volume to csv , it was impossible to access c:\clusterstorage with explorer, cmd or powershell. All Hyper-V Roles (VMs) works and no ressource went offline. No Event (accept explorer.exe hang). Nothing!!!! :-( I disabled the CSV02 and C:\clusterstorage is accessable again.
All my iscsi targets are on the same open-e cluster. Only one iscsi volume causes crashing!
I dont think that the iscsi connection is the problem. At the local test it works fine and 6 other csv's with the same config works fine.
Thank you for any help
best
