During VMworld this year, I attended at nice session on vSAN troubleshooting tips. There are some tools that help us to find a root of problem:
- Health Check
- vSAN Observer
- vRealize Operations Manager
- vRealize Log Insight
There are some commands as below examples:
- esxcli vsan network list - Verify which VMkernel adapters are used for vSAN communication
- esxcli vsan storage list - List storage disks claimed by vSAN.
but quickly we can check health of vSAN cluster by running the following command:
- esxcli vsan health
Ruby vSphere Console (RVC)
RVC is a useful tool (an interactive command line) - as part of vCenter Server (Windows and the vCenter Server Appliance) to manage or perform troubleshooting on vSAN cluster.
- Monitor performance statistics for a vSAN Cluster.
- Provide access through a web browser.
- Capture the statistics for customer use or for VMware.
