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
Regards
Mohammed
