Veeam VMware: Virtual Machine Consolidation Needed status Alarm

Previous page Next page Print this Topic

Table of contents

This monitor tracks the vCenter alarm that is triggered when virtual machine Consolidation Needed status is set.

By default, the alarm is triggered by the following events:

com.vmware.vc.VmDiskConsolidationNeeded
com.vmware.vc.VmDiskConsolidationNoLongerNeeded

vSphere may report that consolidation is needed in case there is a snapshot on the disk which should be deleted, but the deletion process is stuck in the Consolidation state for one of the following reasons:

Datastore performance is low and snapshot deletion/consolidation is timed out;
The datastore does not have enough space to perform consolidation;
A vSphere or a 3rd party application/process is locking the snapshot which should be deleted;
A vSphere or a 3rd party application/process fails to consolidate a snapshot after the snapshot has been deleted. This could be caused by some connectivity issues between the vCenter Server and ESXi host.

If consolidation is needed, perform it manually using the vSphere Client or the ESXi command line. For instructions on how to consolidate snapshots, see this VMware KB article. When the consolidation process is over and succeeded, the monitor will be resolved and switched to the Healthy state.
