iSCSIprt errors 9, 39 and 129 on Windows Server 2012 R2 Hyper-V hosts
Hi,
We’re migrating from Vmware to Microsoft Hyper-V 2012 R2. We’re going to set up a 4 node cluster and have set up a cluster shared volume for storage. At the moment we have 3 nodes up and running. Originally we planned to team our SAN-nic’s but after reading several white papers and browsing several web sites, we changed our plan and landed on using two SAN-nic’s, each with its own IP.
We’ve created two virtual SAN switches in Hyper-V for fault tolerance.
The VMs are a mix of Windows Server 2003 R2, Windows 2008, Windows 2008 R2, Windows Server 2012 R2 and Windows 7, with roles such as IIS, File Cluster Services, App servers and DB servers.
We’re now experiencing that the VMs freeze in the middle of an operation and our users are starting to complain about these freezes and system halts. Users are accessing resources through our Citrix farm.
In the event viewer on our Hyper-V hosts we get a lot of iscsiprt errors and we suspect these errors have something to do with our problems.
We’ve not been able to find any suitable solution googling the errors we receive. We’re not sure who to address this issue to. Is it Microsoft or is it Dell?
Hardware:
Dell M100e Chassis
Pass-through module
Dell PowerEdge M710HD
192GB memory
2x146GB
2xIntel Xeon E5645
6 Broadcom BCM5709S nics
Dell PowerConnect 6248
Jumbo frames is not enabled on the servers with access to our SAN. SAN traffic is on a separate LAN not accessible through our firewall.
3xEquallogic PS5000X
1xEquallogic PS6000

Firmware is 6.0.4

I had similar iscsiprt errors in a Server 2008 R2 Hyper-V environment, on hosts and guests. Was never able to find a root cause, but, Dell technicians strongly believed it was some issue with the iscsi initiator built into Windows.
Aside from that, I'd really consider dumping the Broadcom NICs. The list of problems I've experienced with them is endless, particularly in the Hyper-V world. I've worked with many Dell technicians who believe Broadcom NICs are not production-worthy devices. Switched over to Intel NICs after years of troubleshooting various issues and nearly all were resolved immediately. Might be worth considering this to rule out that Broadcom isn't the root of your problem. Hope this helps.

We're not licensed to upgrade our ESX to a higher level than 4.1. As soon as we've resolved our issues mentioned above, we'll reinstall our remaining ESX and include it in our Hyper-V cluster.
RE: Info Messages. Yes, we have a lot of logon request by initiator messages. What do they mean?
One pool has got 2 members and another pool has got 3 members.
RE: Broadcom. We're on Broadcom firmware 6.4.5

Tommy
