There is no supported method from host CLI, only via RVC:
One could set the CLOM repair delay to 0 temporarily via host CLI bit this would need to be applied to all hosts in the cluster.
fredzhang you can do this with PowerCLI 11 if you do not wish to use the RVC:
$Cluster = Get-Cluster -Name "ClusterName"
# Load the vSAN vC Cluster Health System View
$VVCHS = Get-VsanView -Id "VsanVcClusterHealthSystem-vsan-cluster-health-system"
# Invoke the Fix for all objects
$RepairTask = $VVCHS.VsanHealthRepairClusterObjectsImmediate($Cluster.ExtensionData.MoRef,$null)
