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. The so-called “…vmware.h4…” plugin was in a N/A state. In the past this plugin has appeared several times and should be unregister beforehand, this is the VMware Cloud Director Availability Plugin, which cannot […]

Dell VxRail / vSphere 8.0.310 Update – Advisory Report identified issues with BOSS Device

In a VxRail 8.0.300 deployment, I wanted to upgrade the appliance to the latest 8.0.310 after the initial cluster deployment, but I was confronted with a very strange phenomenon in the advisory report. Important details: Normally, all components of a VxRail node are updated with the RASR or Update image to the version provided by the Image, e.g. 8.0.300. This time, however, I was confronted […]

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 […]

How to kill a Dell iDRAC Session of another User

Now one or the other will ask themselves, why should I kill an iDRAC session of another user, well, if you know the admin credentials of the iDRAC anyway and the colleague has e.g. forgotten to close his iDRAC session and has gone on lunch break and you absolutely want to complete the RASR process of the VxRail – then it might make sense to […]

Dell PowerProtect Data Manager Root Password expired

As the title of the blog post says, it is about restoring the root password of the PowerProtect Data Manager. Because once this password has expired, the system will not run properly until the password is restored. You can set the expiration time for passwords to “never” in the UI of the PPDM, which I recommend for HomeLab purposes, but never for productive environments! Important: […]

Starting in the welcome area, you can select whether you want to restore from a backup or whether it is a new installation. In my case it is a new installation, I skip the view of the EULA which we have to accept either […]

Another Day another Warning inside vSAN Skyline Health. 🙂 Frequent Deletion of VMs….. Hmm….. I’ve been using vSAN since vSphere 6.7 U3 in my home lab and I’m pretty sure I deleted VMs more frequently, especially in my rookie times and never had this kind of warning in vSAN Skyline Health.

Since dark sites are not uncommon, I thought I would describe the process. If you look under Application Settings -> Console and Plugins you should see plugin installation options for an OME appliance with internet access, in a dark site this does not happen […]

Dell VxRail 7.0.482 deployment validation with external vCenter fails

I recently had a VxRail deployment with an external vCenter, which drove me crazy. 🙂 In the normal case, if you select “Join existing vCenter Server” under Global Settings (Step 7), the next Cluster Configuration steps should adapt. This means that under Virtual Network Settings (Step 12), under vCenter Server Network, you only have to choose between Static or Ephemeral Binding. However, I had the […]

The number of VMware vSphere HA datastores for this host is 0, which is less than required: 2

Recently I had the situation that at cluster level, the vSphere HA displayed a heartbeat of datastores at zero, whereby I have defined two specific datastores under vSphere HA settings under Heartbeat Datastores and these must always be pingable. The two defined datastores were no longer visible under Datastores, which is why the warning appeared. After consulting with the storage team, it turned out that […]
