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 will cause 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- 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.
