Today I am wearing my “Keen Upgrader” hat! I have been upgrading my lab environment and got stuck with VMware vCenter Operations Manager upgrade. The procedure is quite straight forward and is well documented. The procedure consists of two steps (see here): Upgrade vCenter Operations Manager vApp; Upgrade the OS to SUSE Linux Enterprise Server […] When using third-party management products for vCenter Server, these plug-ins appear in the Available Plug-ins list. Some of these products may not have an uninstaller to remove the entry under Available Plug-ins or have been deleted/uninstalled before the plug-in was unregistered from vCenter. For example, we ran a PoC for vFabric Data Director in the […] VMware vCenter Support Assistant Appliance installation step 1 – Configure “Lookup Service address” failed with the error message: “Cannot connect to the lookup service at the specified URL. Check if the URL is correct”. I tested the URL and DNS configuration on the VA – all OK.

In order to stop vCC from continuing in this state perform the following steps: In the vCC Server web interface go to the […] I had to re-visit a vCloud Connector environment I built quite a while ago but could not login to neither VMware vCloud Connector Server nor Node with the admin account. I was sure that I did not change the default password (vmware) so was the customer. I also checked that admin account was not locked […] I had a problem activating TM DS Agent with symptoms similar to the ones described in Trend Micro Knowledge Base / Solution ID 1095437 “Anti-malware module of the Deep Security Agent (DSA) shows “Driver offline / Not installed” in the Deep Security Notifier“.
