With this steps I’ve got the Update Manager running again, but I’ve decided to reset the whole database and data folders, because I’ve to upgrade all my hosts to 6.5 and then all old vibs would remain in the database. If there is another missing directory repeat the step for this one. cat /var/log/vmware/vmware-updatemgr/vum-server/vmware-vum-server-log4cpp.log If the error persists check the logfile again. Now I’ve chown and chmod the uploaded folder (in this case EMU)Īfter that retry the “Scan for Updates”. The scan should be completed successfully.Ĭopy the missing folders from the old Update Manager to the vCSA into /storage/updatemgr/patch-store/hostupdate/.Assign them to your Cluster or a separate host.

In the Admin View of VMware Update manager you will see that all Baselines are gone.Maybe you have to log out and log back to the vSphere Web Client.Start the VMware Update Manager service.usr/lib/vmware-updatemgr/bin/updatemgr-util reset-db If you have already deleted the machine and have no backup, you have to use solution #1… If you have it scroll down to solution #2 Solution #1 – Reset the Update Manager Database If you want to stay with the old data you can transfer the missing files from the old Windows-based Update Manager.
Vcenter 6.5 cannot synchronize host manual#
If you have not so many manual added vib’s it is the easiest way to drop all data from the Update Manager Database and folders. Those directories were created after uploading additional vendor vibs to the Update Manager. This directory is one of several directories which wasn’t transferred from the migrator. All baselines and groups were there and I could configure them.īut the “Scan for Updates” always terminates after seconds with the unknown error.Īfter looking in the logfiles I’ve found one log with ERROR lines, where a directory could not be found. My first thought was that the Update Manager is working fine. Before the upgrade everything works fine and the upgrade of the vCSA was easy to and finished without any error.Īfter some research and logfile analyzing I found two solutions. If you are using the vSphere Client to communicate directly with the ESXi host, the communication goes directly to the hostd process.After upgrading my production vCSA from 6.0 to 6.5 U1d, the “Scan for Updates” always runs in an unknown error. When you are logged in vCenter Server through vSphere Web Client, vCenter Server passes commands to the ESXi host through the vpxa process.

Vpxa acts as an intermediary between the vpxd process on vCenter Server and the hostd process to relay the tasks to be performed on the host. virtual machine creation, migration, removal, etc…). Most commands come from vCenter Server through hostd (e.g. The hostd process runs on the ESXi host and it is used for managing most of the operations on the host. vpxa communicates with the ESXi host agent named hostd. The vpxa process is started on the ESXi host when it is added to the vCenter Server inventory. vSphere Client can communicate with both a vCenter Server instance and an ESXi host.Īccess to the ESXi host is provided by a vCenter Server agent named vpxa. Caution: When an ESX/ESXi host is removed from the vCenter Server inventory, the virtual machines are removed from their respective folders, performance data for the host is lost, and any Distributed Virtual Switch configurations on the host need to be reconfigured. VSphere Web Client can be used to communicate with a vCenter Server instance, but it cannot be used to communicate directly with an ESXi host. Remove the host from the inventory within vCenter Server.
