I am deploying vCOPS 5.8.4 on an ESXi 5.5 environment, but get this error in the configuration:
Please advise? Do I need to replace a certificate?
Check whether the date in the virtual appliance is before the
notBefore date/time in the Certificate validity period. You may use the "date" command and get the VA date/time.
Also this issue can occur if the date on both the appliances are incorrect.
Log in to the console of the vR Ops appliance. Typically, you'll log in as the "root" user.
Run the command "date". It'll show you the date.
you do it as with any other Linux OS, there is no difference
use the same "date" command, but type the current date after it in the specific format (type date --help) for usage.
note: it is very important to have dates on both vc ops VMs and the virtual center synchronized!
This is mentioned in the install admin guide as well.
So once you fix the dates, make sure you have NTP enabled on the ESX hosts (or the VMs) to sync the time correctly from now onwards
I will check NTP settings. My understanding was that NTP only syncs time, not date, so I will recheck all components.
I have also found this:
The VM Tools on the vR Ops VAs will sync the time with the host, so I'm expecting your host time to be the root cause of the problem. If you want to switch to NTP, though, that would also work. I would still fix the host time and get NTP configured for it.
Some history.. enabling NTP on the vR Ops VA was a big requirement in v5.x for customer looking to get their solution compliant with STIG standards. if you've got VM Tools sync'ing, you don't need NTP configured on the VA directly, however if you've got gov't standard or other levels of compliance/certification it's necessary.
