I have installed PVA management node in one of the containers. In another container I installed PBAS. Both were working fine till yesterday. Today morning the server CPU was running but there was no signal on the display and i was not able to ping the ip addresses of containers also. So i restarted the server and I logged into PVAMN, the hardware node shows a warning that " License is not Installed". When I tried to install a license key, there was no hardware nodes shown. so I failed to install the key. The ip address of container in which PBAS is installed is not pinging now from the physical server. But when I ping it from the same container it is pinging succeessfully. Now the PBAS also is not working. How can I solve this.
