Hi...
I have an IBM BladeCenter S with 3 blades and an IBM System Storage DS3300 (ISCSI).
In each blade is running Windows Server 2008 R2 withHYPER-V, Failover Clustering with Cluster Shared Volumes.
I have observed that many errors occur constantly in "Failover Cluster Manager" and some VM´s are relocated to another blade automatically, however thoses VM´s sometimes no longer responds to network activity.
The errors I have observed in the "Failover Cluster Manager" are:
Source: Microsoft-Windows-FailoverClusting
Event ID: 1069
Description:
Cluster resource 'Virtual Machine' in clustered service or application 'SERVER' failed.
Source: Microsoft-Windows-FailoverClusting
Event ID: 1205
Description:
The Cluster service failed to bring clustered service or application 'SV-DBURAS' 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.
Another error (warning type) that is constantly generated in the SYSTEM events (Mirage is the storage name):
Source: ds4dsm
Event ID: 769
Description:

Source: ds4dsm
Event ID: 10

Event ID: 801

Thank you in advance any help!
