VMware Tools Heartbeat Failure during Snapshot Removal ?

[TonyJK]

We are using vSphere 5.1 with vRanger 6 for backup.

For a particular VM with VMDK file of size around 600GB, we find that we get the "vSphere HA VM monitoring error" whenever the vRanger completed and attempted to remove the snapshot.

Besides, it appears the VM cannot be reset by vSphere HA as we get the message "vSphere HA cannot reset this VM".

We would like to seek your advice

1) Why we get the "vSphere HA VM monitoning error" and how to avoid it?

2) Why HA reset failed (We indeed don't want to get it reset) ?

3) Should we turn off "vSphere HA VM monitoring" for this particular VM ?

Your advie is sought.

Hi,

1) Why we get the "vSphere HA VM monitoning error" and how to avoid it?

>>  You might have VM monitoring enabled, if you dont want to enable.

• Log in to the vCenter Server using the vSphere Client.
• Right-click on VMware HA Cluster and choose Edit Settings
• In the Cluster Settings dialog box, Select VM Monitoring
• VM Monitoring Status: VM Monitoring drop down box, select Disabled
• Click OK

2) Why HA reset failed (We indeed don't want to get it reset) ? 

You can refer this doc if applicable to you

3) Should we turn off "vSphere HA VM monitoring" for this particular VM ?

>> If is it high I/O intensive VM, yes it will good idea to off vm monitoring

This KB applies to your situation since in other post  you have mention about ALl Path dead.

In addition to what memaad mentioned, you may want to take a look at VM and Application Monitoring for additional information.
