Symptoms

Health-check returns an event indicting a Warning or Failure from the vSAN health report. Test ResultResult CodeResult InterpretationPass0No errors were found from the vSAN health report.Warning1VxVerify found at least one Warning from the vSAN health report.Failure2VxVerify found at least one Failure from the vSAN health report.Critical3This test has no critical result. Each test that passes is not listed in the summary report, for ease of reading.An example of the health-check output is shown below: ========================#======#=========#====================================================================#==============# | Hostname / Category |Status Dell_KB | Warnings or Failures, unless tests Passed ; Product S.N. | #========================#======#=========#====================================================================#==============# | `` | Warning 217884 | vs_cluster: vSAN Disk Balance, Warning |

Cause

The VxVerify test 'vs_cluster' using the vCenter (VC) API, collects the result of the Cluster Health check. The Cluster Health group of vSAN health-checks checks the following: 'Time is synchronized across hosts and VC''Advanced vSAN configuration in sync''vSAN daemon liveness''vSAN Disk Balance''Resync operations throttling''vSAN Direct homogeneous disk claiming''vCenter state is authoritative' 'vSAN cluster configuration consistency''vSphere cluster members match vSAN cluster members''Software version compatibility''Disk format version''vSAN extended configuration in sync' The VxVerify upgrade test profiles are focused on issues likely to cause upgrades to fail. Therefore, issues that do not affect an upgrade are not in the upgrade healthcheck profiles.The full results for the VMware vSAN Health check are listed in the vxv.log file. This log is in the same folder as the rest of the VxVerify logs (see article VxRail: How to run the VxRail Verify tool for log locations).
