Q: What does the 'Local protection - virtual machine health' Health Check do?
This health check monitors the status of snapshots for virtual machines to ensure effective local protection. It also provides detailed information such as failure reason and timestamp for the last failed snapshot to facilitate prompt identification and resolution of the issue.
Q: What does it mean when it is in an error state?
When the health status is in an Error state, it indicates one or more VM snapshot failures. If any VM in a protection group experiences snapshot failures, the state in the health check table will be marked as Red.
Q: How does one troubleshoot and fix the error state?
Users need to refer to "Failure reason" in health check table for the remediation guide. For each VM under protection groups, the health check will monitor the latest snapshot status and also the continuous failures. If the VM snapshots keeps failing, most likely it's not caused by the vSAN data protection service but other underlying infra issues and users need to take a further look on the specific VMs.
