I am new to server 2012 and trying to create a cluster for sql 2008 enterprise on windows server 2012. In order to achieve this i have configured a DC and two cluster nodes. All servers are running server 2012 standard edition. My windows vms are running on kvm hypervisor. I have created iscsi virtual disks on DC in order to share storage with cluster. I have created separate virtual disks for sqllogs and data etc. I had mounted shared storage with the same drive letters on both cluster nodes. The cluster node on which m running cluster manager can see and mount successfully all shared storage but mounted partitions on second node disappear for some reasons. I can see partitions in disk management and tried to online the disks but error appears" The specified disk or volume is managed by Microsoft failover clustering component. The disk must be in cluster maintenance mode and the cluster resource status must b e online to perform this operation". There are three consecutive event id's i saw in events (10, 70, 1) source : iScisprt : login request failed. "The login response packet is given in the dump data". "Error occured when processing iSCSI logon request. The request was not retried" Initiator failed to connect to the target. Target IP address and TCP Port number are given in the dump data".
Before creating the cluster both nodes were able to persistent mount the partitions. If I manually shutdwon node 1 which is cluster manager, then node 2 becomes active node and partitions are visible and persistent mounted, then mounted partitions no longer visible on node 1. Has anyone experienced the same issue or know any solution for this? All comments are welcome and highly appreciated. Thanks
