vCenter installation fails on Windows Server 2012

March 12, 2013

During the installation of vCenter 5.1 on a Windows server 2012 I ran into an issue where the installation of the vCenter failed. The prerequisite services installed without problems but the vCenter service failed to install. The installation stopped with a Failed to install VMware vSphere Profile-Driven Storage error. Looking at the services I noticed that the vCenter services was already installed but not running. When I tried to manually start the vCenter server service it failed with an error regarding a dependency service not being available.

Integrating Hyperic in vCenter Operations

January 10, 2013

Integrating Hyperic within VCOPS is fairly simple and similar to integrating other solutions. VCOPS uses adapters to establish this integration. First step is to install the Hyperic adapter, this process is the same as updating the VCOPS installation. Open the update tab in the administration portal. Point the update field to the Hyperic adapter .pak package you downloaded earlier and hit update. VCOPS will now install the Hyperic adapter. Installling an adapter is the same as updating VCOPS.

March 16, 2012

One of our vSphere host showed as disconnected in vCenter. Connecting directly to the host with the vSphere client wouldn’t work neither. When restaring the services on the host I was able to connect directly but within one minute the connection between the client and the host would be lost. As I had already encountered something similar before I checked the partitions on the hosts. The vdf -h command shows that the hostdstats partitiion has filled up.
