I recently encountered an error in VMware vLCM: “Feature cannot be enabled on this cluster”. This was followed by another message: “Failed to fetch vSAN witness host associated with the cluster.”
I have recently encountered the following error on several Lenovo VX systems, which prevents vLCM from initiating the upgrade from ESXi 7 to ESXi 8:
Error: Version iavmd-3.0.0.1038 of the manually added Component Intel VMD driver with VROC support is an unsupported downgrade from version iavmd-3.5.1.1002 on the host.
Replace the Component in the image with one of the same or higher version.
If you encounter the error mentioned above while using VMware vLCM in conjunction with the “HPE OneView for vCenter Plugin,” there is a high likelihood that you can resolve the issue by executing a specific command directly on the ESXi host. To do this, you will need to access the ESXi shell or SSH into the host:
sut -set mode=AutoDeploy
This command sets the mode to “Auto Deploy,” which is essential for ensuring proper functionality with VMware vLCM and the HPE OneView integration.
To verify the current mode of your ESXi host, you can retrieve this information by executing the following command:
sut -exportconfig
For quite some time I have observed a LOM warning in VMware health status tab on an HPE Proliant ML350 Gen10 server. It seems like it reports the warning on two NIC that are down, even though there are unused by ESXi.
This blog post is not about the L1 Terminal Fault (L1TF -> VMware KB56931) but about the HTAware Mitigation tool version 1.0.0.9 (HTAwareMitigation-1.0.0.9.zip) that seems to have issues when used on single hosts (instead of clusters) – here is the problem that I have observed.
You run the command:
Set-HTAwareMitigationConfig -VMhostName <hostname> -Enable
Followed by
Get-HTAwareMitigationConfig -VMhostName <hostname>
Get-HTAwareMitigationConfig not working on single host
As you might see the “Set-HTAwareMitigationConfig -VMhostname <hostname>” command doesn’t seem to do anything!
I recently wanted to make sure that my lab environment was on the latest VCSA version (Platform Service Controller and vCenter) so I went to the VAMI interface on my PSC and quickly discovered that there were no updates – that’s was strange because my PSC was at build 8217866 (build 6.7.0.10000) and according to the vSphere version list KB2143838 there has been released some newer versions Continue reading
