Cause

vSAN plug-in is missing in the path location: 
/usr/lib/vmware-vpx/vsan-health/ui-plugins/ 
When the vCenter server is rebooted, it loads the vSAN plug-in from the following folder:  
/etc/vmware/vsphere-ui/vc-packages/vsphere-client-serenity/
It extracts the vSAN html5 package to: 
 /etc/vmware/vsphere-ui/vc-packages/vsphere-client-serenity/





Resolution

To resolve this issue: 

Copy the vSAN plug-in from another vCenter server with the same build number. If a different vCenter build number is used, it causes the vSAN plug-in to fail to load.  
root@vcsa01 [ ~ ]# mkdir -p /etc/vmware/vsphere-ui/vc-packages/vsphere-client-serenity/com.vmware.vsphere.client.h5vsan-<get vCenter build from from vsphere_client_virgo.log >

mkdir -p /etc/vmware/vsphere-ui/vc-packages/vsphere-client-serenity/com.vmware.vsphere.client.h5vsan-7.0.2.200

root@vcsa01 [ ~ ]# unzip vsan-h5-client.zip -d /etc/vmware/vsphere-ui/vc-packages/vsphere-client-serenity/com.vmware.vsphere.client.h5vsan-6.7.0.13000

unzip vsan-h5-client.zip -d /etc/vmware/vsphere-ui/vc-packages/vsphere-client-serenity/com.vmware.vsphere.client.h5vsan-7.0.2.200

root@vcsa01 [ ~ ]# service-control --stop vsphere-ui
root@vcsa01 [ ~ ]# service-control --start vsphere-ui
Alternatively, deploy a temporary vCenter to the customer's environment and extract the plug-in from that VM.
