Unable to login to the vSphere Web Client after VCSA 6.0U1 upgrade to 6.0U2


After an upgrade of a VCSA 6.0U1 to 6.0U2, I was unable to login to the vSphere web client. Also the login screen was a little bit messed-up like you can see on the screenshot below. When I entered a login name and a password it directly showed User name and password are required, like […]

Configure a HTTPS proxy for vCenter VAMI updates


I just needed to update a customer’s vCenter server from 6.0U1 to 6.0U2. As I didn´t have access to the vSphere cluster where the vCenter VM itself was running, I tried the update option via the VAMI interface. The vCenter was unable to directly connect to the internet but I got a proxy URL from […]

Removing multiple VMs / entries from the VMware Horizon View Composer Database


Manual modifications in the VMware Horizon View ADAM or Composer Database can be a very annoying task. Last week a customer had a serious problem with a View 6.2 installation, which led to many left over entries of linked clones in the Composer SQL database. In the KB 2015112 VMware lists all relevant tables and […]

Nutanix: Metro Availability & vSphere 6


During some tests with metro availability in the lab with NOS 4.5 and vSphere 6 I noticed that it was not possible to pair the two Nutanix clusters as usual.

Nutanix: vmnic down warnings after vSphere 6.0 upgrade


After we upgraded our Nutanix clusters some days back from vSphere 5.5 to vSphere 6.0 we got a massive amount of ongoing warnings, which claimed that two vmnics on each node were down (“Link on NIC vmnicX of host xx.xx.xx.xx is down”).

Nutanix: Unable to delete container / VDisk(s) not marked for removal


If you are unable to delete a container within Prism this is mostly related to remaining files on the datastore / container. When you try to delete the container you will get an error message like “Container {container-name} contains VDisk(s) 123, 456, 789 not marked for removal.” Mostly it should help if you remount the […]

Lab results: Benchmarking a Nutanix Block


The last weekend I spend some time in our solutions center at work to play around with a Nutanix block. I thought it would be interesting to benchmark the system to see how much performance you can get out of it and would like to share the results with you in this post. Hardware & […]

VMware vSphere 6: Hidden C# client enhancement


I have seen multiple vSphere environments in the last couple of months, which had a lower EVC baseline as necessary configured with vSphere 5.5. The reason in these cases always was that the customer used the vSphere C #client for all kind of configurations. If you have an Intel Ivy Bridge CPU in your ESXi […]

Troubleshooting Veeam B&R plugin for vSphere Web Client


Recently one of my customers had problems to get the Veeam Backup & Replication Plugin working for the vSphere Web Client. The Veeam Enterprise Manager (v7) was configured correctly and showed, that the vCenter Server was registered and the plugin installed. Still the plugin did not show up in the web client. The customer already […]
