Iscsi Initiator Windows 2008 R2 Target Error

Windows Server 2008 R2 Servers and Microsoft iSCSi target software on one of the servers (Server A). Setup a target iscsi initiator quick connect failed and Virtual Storage on Server A.

error message". The error log shows event ID 41 (WinTarget error, "The iSCSi target rejected a connection request from local computer"). Thought it might be the initiator so I downloaded the Starwind initiator client, but getting connection requests denied as well. All firewall settings and port 3260 seem fine. Any ideas on what's stopping the iscsi initator on server A from connecting to the target on Server A?

I have my QNAP 859URP+ connected through LAN1 to my switch. It gets it's IP from our DHCP server. I want to connect LAN2 directly to the server. I have the following settings: QNAP LAN1 (connected to switch) IP: 192.168.0.9 MASK: 255.255.255.0 Gateway: 192.168.0.254 QNAP LAN2 http://serverfault.com/questions/304513/error-trying-to-connect-to-iscsi-target-with-windows-initiator-on-w2k3 (connected to the 2nd NIC on the server) IP: 192.168.111.1 (default) MASK: 255.255.255.0 Gateway: NONE On the server, the 2NIC that is connected to the QNAP LAN2 has the following: IP: 192.168.111.2 MASK: 255.255.255.0 GATEWAY: NONE (first NIC is DHCP'ed) I am able to ping to the 192.168.111.1 from the server (and not from any other pc/server on the network - that's good), but when trying to access/add from the Windows iScsi Initiator - I get an error: connection failed.

I'm using the Microsoft iSCSI Target that's available for Windows Storage Server 2008, but when I try to connect to the target to perform discovery I see no targets. What's iscsi initiator wrong? Q. I'm using the Microsoft iSCSI Target that's available for Windows Storage Server 2008, but when I try to connect to the target to perform discovery I see no targets. What's wrong? Jan 17, 2010 John Savill | Windows IT Pro EMAIL Tweet Comments 0 Advertisement A. Assuming you've configured iSCSI correctly, have enabled all the necessary firewall exceptions, and have IP connectivity, the next item would be to connect to the iscsi initiator windows iSCSI target. The easiest way is using the Discover Portal under the Discovery tab of the iSCSI Initiator administrative tool. Just type in the IP address or name of the iSCSI target, as shown. You should see a list of available targets under the Targets tab after clicking Refresh, but you may not see any. The most likely cause for not seeing the targets is that you haven't added the initiator's iSCSI Qualified Name (IQN) to the target. The only targets shown are those that the initiator has permission to use, so if you haven't added the initiator IQN to the allowed list for the target, no targets will be displayed. To resolve this, add the initiator's IQN to the allowed list: Access the Microsoft iSCSI Software Target management interface (Server Manager, Storage, Microsoft iSCSI Software Target). Expand iSCSI Targets. Right-click a target that the client should be able to access and select Properties. Select the iSCSI Initiators tab. Click the Add button and enter the IQN of the initiator (you can check the IQN of the initiator through the Configuration tab of the iSCSI Initiator app on the client). Click to expand. Click OK to all dialogs. On the iSCSI Initiator Targets tab, click Refresh and the targets to which the initiator has access will be displayed. Relat

Community! Creating your account only takes a few minutes. Join Now My biggest problem is the Event Id 20 from source ISCSIPRT which reads "connection to the target was lost. the initiator will attempt to retry the connection". I want to monitor this and try to see the symptoms before it actually happens. Background on my environment: - Dedicated Netgear GS716T gigabit switch just for SAN traffic on its own 10.0.0.x subnet. Flow control is on.  Jumbo Frames is off. Spanning tree is off.  Using CAT 6 network cables - Infortrend Eonstor SAN device with 2 ethernet ports.  12 TB raw disk using RAID 6 giving a little less than 8 TB usable.  I have set it up as 1 Logical Drive with 7 several partitions.  Partitions 1,2,3 each have their own LUN and are going thru NIC #1.  Partitions 4,5,6,7 have each have their own LUN and are going thru NIC #2.  Jumbo frames is off.  NOT using any Multipathing feature as the vendor is not supporting LUN MASKING (A BIG DRAWBACK FOR ME!!!!) - Server #1 is running Windows 2003 Std SP2 32-bit using Ms iscsi initiator to connect to iscsi target on NIC #1.  That gives 3 drives appearing on the server (partitions 1,2,3).  Server #1 is using dedicated NIC for SAN traffic which is Intel Pro 1000 MT Server NIC.  I then have several folders shared out on network for clients to access.  - Server #2 is running Windows 2003 Small Business Server Standard SP2 32-bit using MS iscsi initiator connecting to target on NIC #2.  that gives 4 drives appearing on the server (partitions 4,5,6,7).  Server #2 is using dedicated NIC for SAN traffic which is Intel Pro 1000 MT Server NIC. I then have several folders shared out on network for clients to access. Here are some of the steps I've taken: ... I've added a few counters to the Windows performance monitor. I found this post thru the MS Technet Performance Team blog which offers a few ideas: http://blogs.technet.com/b/askperf/archive/2010/12/03/performance-counter-for-iscsi.aspx

... Also, according to MS Iscsi initiator guidelines, I have modified registry to change the TcpAckFrequency to a value of 1  ( HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces ) ... I have made sure that the TCP Nagle algoritm is turned off according to the following suggestion: http://smallvoid.com/article/winnt-nagle-algorithm.html

Anyone else find ways to pay attention to your iSCSI connections?   EDIT: I also followed the instructions in this MS KB article "In Windows Server 2008 or Windows Server 2008 R2 environment, if the network environment is set to enable Delay ACK and storage is connec
