You can check the health of the Virtual SAN cluster.
You can use the Virtual SAN health checks to monitor the status of cluster components, diagnose issues, and troubleshoot problems. The health checks cover hardware compatibility, network configuration and operation, advanced Virtual SAN configuration options, storage device health, and virtual machine objects.
The Virtual SAN health checks are divided into categories. Each category contains individual health checks.
|Health Check Category||Description|
|Hardware Compatibility||Monitor the cluster components to ensure that they are using supported hardware, software, and drivers.|
|Performance Service||Monitor the health of a Virtual SAN performance service.|
|Network||Monitor Virtual SAN network health.|
|Physical disk||Monitor the health of physical devices in the cluster.|
|Data||Monitor Virtual SAN data health.|
|Cluster||Monitor Virtual SAN cluster health.|
|Limits||Monitor Virtual SAN cluster limits.|
|Online health||Monitor Virtual SAN cluster health and send to VMware’s analytics backend system for advanced analysis. You must participate in the Customer Experience Improvement Program to use online health checks.|
|Virtual SAN iSCSI target service||Monitor the iSCSI target service, including the network configuration and runtime status.|
|Encryption||Monitor Virtual SAN encryption health.|
|Stretched cluster||Monitor the health of a stretched cluster, if applicable.|
Virtual SAN periodically retests each health check and updates the results. To run the health checks and update the results immediately, click the Retest button.
If you participate in the Customer Experience Improvement Program, you can run health checks and send the data to VMware for advanced analysis. Click the Retest with Online health button.
