One of the most interesting is the integration of PowerEdge Servers, from which you can view various alarms about: These are exactly the informations I want to integrate into Aria Operations to get/build a dedicated dashboard.

PowerCLI: Connect-VIServer The SSL connection could not be established

I wanted to make my life easier again in a customer situation and use my PowerCLI scripts to shorten repeating tasks.

When I tried to use my script, I got the following error message: So it’s all about certificates, let’s take a look at our current PowerCLI configuration: As you […]

As part of a vCenter 7 to a brand new vCenter 8 migration, the vSAN clusters had to be moved in addition to the normal clusters. When we disconnected the vSAN Witness Appliance from the old vCenter in the last process and then wanted to add it to the fault domain in the new one, we were confronted with the following error message: Although these […]

Host prevents entering Maintenace Mode: There are insufficient memory resource on standby hosts

In a vSphere 8 – 2-Node Cluster Update I have had to deal with the following message during the Check Compliance process: High Availability (HA) Admission Control is enabled and set to specify a failover host, which is reserved for HA failover purposes.

A problem with one or more vFAT bootbank partitions was detected. (PSOD Alarm!)

Corrupt vFAT partitions already existed in vSphere 6.7 times and unfortunately they also appear today with vSphere 8. The problem? If you go through with the upgrade in […]

Moving a vSAN cluster from one vCenter Server to another

vSphere 7 to 8 updates are slowly in full swing, many customers are migrating to October ’25 -> EOL for vSphere 7. Some of my customers want a brand new vCenter right away, because some of theirs are still from version 5, the ex-colleague fiddled in the Postgre database before he quit and so on and so forth – the reasons seem to be endless.

Image Compliance shows hardware compatibility issues

During an ESX server cluster update on image basis, I was confronted with a strange thing. The message says that there are hardware compatibility issues. However, if you look at the details, you will quickly realise that there is nothing under the firmware version. If you then scroll down a little, you will see the warning ‘Device is incompatible with the Driver/Firmware in clusters image‘. […]

vSphere UI Client Plugin is at N/A state before vSphere 8 Upgrade

We are rapidly approaching the end of vSphere 7 support (October ’25), and during a vSphere 8 upgrade pre-check at my customer’s site, we ran into the problem mentioned in the title.

Generate a VMware Aria Operations Passphrase for Node Adding

For new deployments or extensions of Aria Operations Cluster, the admin credentials are required to add the nodes. To prevent this, especially as a security concern, the administrator can generate a temporary passphrase in the Admin Console of Aria Operations. I would like to describe how this works in this blog post. First, we log in to the admin console of Aria Operations: Under “Nodes […]
