Failed to failover SQL instance from one node to another

Hi,

I am experiencing an issue with SQL Server 2012 clustering. Briefly, when I move SQL instance from node SQ1 to node SQ2 to process fails.

At the beginning of the process, the cluster try to change to owner to SQ2 but somehow it fails back automatically to SQ1 and the following errors are thrown in cluster event viewer :

Event ID:1205

The Cluster service failed to bring clustered role 'SQL Server (MSSQLSERVER)' completely online or offline. One or more resources may be in a failed state. This may impact the availability of the clustered role.

Event ID:1069

Cluster resource 'SQL Server' of type 'SQL Server' in clustered role 'SQL Server (MSSQLSERVER)' failed.
Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it.  Check the resource and group state using Failover Cluster Manager or the Get-ClusterResource Windows PowerShell cmdlet.

Any idea can lead to resolve this issue

Thanks,

TF
