Unable to delete an “inaccessible” datastore (Zombie datastore)

I built a new storage array and migrated the VMs accordingly. But the server gave the following error message: I noticed that the old datastore is still shown as “inaccessible” in vCenter: And even via esxcli I don’t see the datastore anymore: So I first choose the classic way, putting the Server in Maintenance Mode and “Reboot does Good”. But the inaccessible Datastore is still […]

Insufficient configured resources to satisfy the desired vSphere HA failover level on Cluster X in Datacenter X

When configuring my vSAN cluster, I forgot to set “in case of maintenance mode, all VMs should be migrated to the other host automatically” under the HA settings. So I made the following settings under Admission Control: Host failures cluster tolerates is at 1, because I have a VMware vSAN ROBO Cluster. So everything was fine and I found out that the Override calculated failover […]

Found another host participating in the vSAN service which is not a member of this host’s vCenter cluster

When reconfiguring my network environment (soon to be seen in the next HomeLab update) the vCenter gave an error message, which you have already read in the subject. In my case, it was about the vSAN Witness appliance. Of course there is also a Knowledge Base article about this error message and the solution according to VMware is: https://kb.vmware.com/s/article/2062704 To resolve this issue, check all […]

“LINT1 motherboard interrupt” error while installing VMware ESXi

I got 3 Dell R730 servers on which VMware ESXi 7.0 U3 should be installed normally.

Accordingly, I wanted to use a Windows Server 2019 template and build a VM from it. In the process, I ran into an error that had not happened to me before: The error message says: Module CPUID power on failed. Failed to start […]
