VSAN Web Client – Edit Button Disappeared


Recently I upgraded my lab and can now run VSAN but as I went to enable it the edit button on the cluster settings wasnt there.  I was also receiving the below error code when accessing the VSAN health section.

Unexpected status code: 400

I came across a KB that fixed the problem, the issue was the VSAN health plug-in did not have read access to the relevant certificate files.  Im using the virtual appliance for vCenter, I have changed my PSC to run as a subordinate CA and im running v6 Update 2.  VMare KB can be found here.

First connect to the vCenter appliance, im using an external PSC but I still do this on the vCenter.  Then run the following

>/bin/install-parameter rhttpproxy.cert

For me this returned nothing so I then run

>/bin/install-parameter rhttpproxy.cert -s /etc/vmware-rhttpproxy/ssl/rui.crt

I then need to check the properties in the folder /etc/vmware-vpx/ssl and make sure they are set to the following as per the KB.

drwxr-x— 2 root cis 4.0K Sep 18 15:35 ./
drwxr-xr-x 14 root root 4.0K Sep 18 16:28 ../
-rw-r—– 1 root cis 3.0K Jun 15 16:53 rui.crt
-rw-r—– 1 root cis 1.7K Jun 15 16:53 rui.key
-rw——- 1 root root 65 May 30 19:55 symkey.dat
-rw-r—– 1 root cis 2.9K Jun 15 16:53 vcsoluser.crt
-rw-r—– 1 root cis 1.7K Jun 15 16:53 vcsoluser.key

buttonerror03

Once changed and they are set to what the KB states I then run the following

>/usr/lib/vmware-vpx/vsan-health/health-rpm-post-install.sh

buttonerror04

Once that has run I then need to reboot the vCenter appliance.  Once rebooted I can now enable and configure VSAN.
