Microsoft iscsi target is not being connect from second cluster node

Environment

Microsoft iSCSI software target version = 3.3.16567

OS = Windows 2008R2 Enterprise

Target A = two disks (2500 MB size) => Created for a Cluster

I created a targets on single Microsoft iSCSI target. Make two disks in iSCSI Target. Target assigned to a cluster. Cluster has two nodes. Only one Cluster node is able to successfully connect to the target(via iSCSI initiator) and while one Cluster node is connected to the target, the other Cluster node is not able to connect to the iSCSI target. Below is a snap when the other Cluster node is trying to connect to the Target.

Any comment will be appreciated. Thanks. Zahid Haseeb.
