Hi,
not sure if I am on the right forum, but maybe someone has any idea where to start troubleshooting the issue. 2 identical Virtual (Hyper-v nodes also Windows 2012) Windows 2012 Cluster Servers with last updates. Couple iSCSI Dell volumes attached through Windows iSCSI initiator as cluster resources. I was using SQL IO tool to test iSCSI drives and one node run test successfully without slowing server at all and satisfied results, but other node server just keeps hanging the server for couple seconds. CPU stays at normal 30-40% but it is not possible to work with server during the test and test results are bad for those drives. Same configuration on both servers.
Any ideas?
thanks
