These days I had to update a ESXi host using vCenter Update Manager (VUM). Environment is managed by a vCenter 6.7 appliance with embedded VUM. The host I got the error is managed by vCenter but not member of any cluster. After attaching a upgrade-baseline and running the compatibility check, I got the error that vCenter Update Manager cannot copy files to the host.
Recently I had to troubleshoot a Veeam Backup & Replication (B&R) problem. There the question popped up which are the running Veeam jobs at point or period of time. The GUI is not a big help to answer this question. Therefore I wrote a small script that show these jobs.
Recently we had to troubleshoot rather high storage latency at a customer site. The environment consists of Hyper-V hosts connecting to 3PAR arrays via iSCSI. 3PAR arrays are all-flash arrays (AFA). I know such problems in vSphere environments too. There higher storage latency can be caused by delayed acknowledgement (DelAck). Read more about this issue and how to configure DelAck on vSphere ESXi hosts here. […]
When a VM is rebooted in OS, it keeps powered on at ESXi host during the whole boot process. Sometime it would be very useful when a OS reboot triggers a cold boot. In this post I show how to cold boot VM by guest reboot. Cold boot is like to power cycle a computer. A VM needs to get through a power off state […]
Most often installing PowerCLI is no problem. Sometimes there is a PowerShell error when accessing PowerShell gallery. Like now: Just wanted to install PowerCLI onto a new Windows 10. When running the command find-module vmware* I get this error(s): Fortunately I found a solution quickly here. Problem is related to security protocols used in PowerShell. Check current protocols by running: My Windows 10 showed this […]

Redirection from old location will work for […]
This post is about two cool and powerful products: VMware vRealize Operations Manger (vROPs) and HPE Primers/3PAR and how to combine them. This post includes current versions of both. Good and a bad news about costs: Bad first: vROPs free for a short period of time as trial. Good one: HPE Plug-In is free! Version 3.7 of HPE Storage Plug-ins for VMware is the first […]
Compared to posts that describe the same task in older versions, this will be a rather short one. Specially replacing vCenter certificates was getting more and more easier during versions. It has never been that easy! In vCenter 7 we just have one certificate to manage. Solution Certificates are gone, respectively are deprecated in 7.0 . You can also see in CLI certificate-manager. See welcome […]
I want to share the solution of flooding errors I had after an vSphere upgrade. Errors are probably not connected to upgrade. The problem I got flooded by errors for VMFS datastores in log files.
