Installed the vCOPS 5.8 virtual appliance for testing. It was working fine until this morning when I powered my lab back on. I can get into https://vcops/admin just fine. When browsing to https://vcops/vcops-vsphere I get an error that says, "HTTP Status 404. The requested resource () is not available".
As the UI VM was booting I did notice that it took a long time to start vcopsService.
I've rebooted the vApp but keep getting the same error. I'm not really sure where to even start to look. Thoughts?
I right clicked the vApp (VMware vCenter Operations Manager) & selected Shutdown. Watching the console of the VMs they both appear to be shutting down gracefully.
I had exactly the same issue in vCOPs 5.8.4 environment.
I fixed it by unregistering ALL vCenter Servers. There was an error message "Operation is complete but service restart failed", after each Unregister operation.
I then re-registered all vCenter Server back... Two vCenters were registered OK but when I tried to register the third, error message "Operation is complete but service restart failed" appeared and vCOPs UI stopped working again... As soon as I initiate Unregister process for that particular vCenter, everything went back to normal. Will investigate this further.
OK, here is an update on this issue:
No matter what I tried to do to re-register a particular vCenter:
...nothing worked! There must be something not right withing the vCOPs database, something that screw everything up...
What I did is followed KB Removing non-existent virtual machines from the vRealize Operations Manager vApp (2020638)
to set quite aggressive DB purging and left it overnight.
The next morning the whole data for that particular vCenter have been purged from vCOPs DB and I managed to add vCenter again.
I hope this will help
