Hi guys,
My Hyper-V server was composed of 2 HP servers, the OS is win2008, they formed a cluster, and the VM’s storage is shared by NetApp Snapdrive.
I met an issue yesterday; one of the Failover Cluster nodes was disconnected to the shared storage, it was missing a disk in ‘Server management\Storage\disk management’ and ‘Server management\Storage\Snapdrive\Disks’ pane.The windows system log was shown as below:
Event ID: 1038 Ownership of cluster disk 'Disk G:\' has been unexpectedly lost by this node. Run the Validate a Configuration wizard to check your storage configuration.
Event ID: 1069 Cluster resource 'Disk G:\' in clustered service or application 'a3d8511b-6232-44a9-9c47-5e65851e2e09' failed.
Event ID: 61110 ONTAP DSM was unable to communicate with the logical unit on DSM ID 03000102. The DSM will attempt a fail-over. The data section of this log entry contains the NTSTATUS code.
Event ID: 15 The device, \Device\Harddisk3\DR3, is not ready for access yet.
Event ID: 61034 The multipath logical unit /vol/vol3/qtree2/{15489d81-9dc6-4a97-82fb-10e7a8c40d34}.rws on storage system CN-COQ-Storage2 disconnected.
The cluster events were shown as below:
Event ID: 1038 Ownership of cluster disk 'Disk G:\' has been unexpectedly lost by this node. Run the Validate a Configuration wizard to check your storage configuration.
Event ID: 1069 Cluster resource 'Disk G:\' in clustered service or application 'a3d8511b-6232-44a9-9c47-5e65851e2e09' failed.
Event ID: 1034 Cluster physical disk resource 'Disk G:\' cannot be brought online because the associated disk could not be found. The expected signature of the disk was '{1b20a5bc-bcd0-489a-b84f-935982eaf484}'. If the disk was replaced or restored, in the Failover Cluster Manager snap-in, you can use the Repair function (in the properties sheet for the disk) to repair the new or restored disk. If the disk will not be replaced, delete the associated disk resource.
Event ID: 1205 The Cluster service failed to bring clustered service or application 'a3d8511b-6232-44a9-9c47-5e65851e2e09' completely online or offline. One or more resources may be in a failed state. This may impact the availability of the clustered service or application.
Event ID: 5121 Cluster Shared Volume 'VHDData' ('Disk G:\') is no longer directly accessible from this cluster node. I/O access will be redirected to the storage device over the network through the node that owns the volume. This may result in degraded performance. If redirected access is turned on for this volume, please turn it off. If redirected access is turned off, please troubleshoot this node's connectivity to the storage device and I/O will resume to a healthy state once connectivity to the storage device is reestablished.
I have been contacted with NetApp; they told me the connection was reset by theinitiator, and they suggest me to contact Microsoft; I want to find the root cause of this issue, so please help me. Thanks in advanced.
