Just a quick command I used. Maybe it will be useful for someone as well. I thought about the easiest way to check for all active and standby uplink ports on all vSphere Distributed Switch portgroups in my datacenter, for documentation purposes. You could easily check the settings on each portgroup by navigating to the… Continue reading Export all active and standby Distributed Switch Portgroup uplink ports using PowerCLI
Last week I came up on a situation on my homelab where one of my VMware ESXi host was not responsive and not connected to the vCSA, even though the virtual machines running on it were not affected. Trying to connect to the host's website I received this error: I connected to the host by… Continue reading VMware ESXi on Dell PowerEdge internal dual SD module may not be responsive
Using the newly released version vCSA and ESXi 6.7U1, it is possible to manage VMware Tools and VM Hardware updates directly from the HTML5 panel. A few notes from myself, as I was asked multiple time during the last few weeks about the option and how it will be implemented into the HTML5 client. As… Continue reading VMware Tools and VM Hardware Update in vSphere 6.7U1
I won't forget to double, double, double check a local NTP service ever again. Everyone knows, if something does not work, it's DNS. I agree. But almost as important as the reverse/forward DNS lookup is the correct time given by a local NTP service. I learned it the really hard way and will probably tell… Continue reading Check the time. Like… really! Check it! VMware PSC queries Windows Server NTP Service
I recently came across an error where I needed to set up a replication between two datacenters using the VMware vSphere Replication appliance. The appliances on both sides were updated to version 184.108.40.2062 Build 6128217 and the vCenter Server appliances as well as the ESXi hosts were on the latest build at 6.5. The environment was… Continue reading vSphere Replication fails at validation to DR site
Just a quick reference to bookmark, may someone think it's useful. Spending time to rescan HBA's on all hosts in a cluster is time consuming and not worth the work. It is possible to rescan all HBA's with a simple PowerCLI line: Get-Cluster -Name “Clustername” | Get-VMHost | Get-VMHostStorage -RescanAllHba or if you have more… Continue reading Rescan all Hosts HBA’s | It’s that simple!

I was facing another really annoying issue recently which was quite new for me. While looking for an acceptable solution I came across a website from Lingeshwaran Rangasamy which I do not want to hide as it describes how to fix it in a few steps. Many kudos to @UnixArena. Hope he doesn't mind my… Continue reading [HOW TO] Unknown root / GRUB passwd prior to VMware vCSA upgrade
Another situation I was facing two weeks ago while upgrading two Windows vCenter Server 5.5 including vSphere Replication Appliances to the latest vCenter Server Appliance 6.5U1. As the upgrade process is fairly known by now, I was sure I will need to reset the email@example.com password due the expiration settings. But I also needed to… Continue reading [INFO] Changing the default SSL password during the vCenter Server certification renewal
I was talking to a friend of mine earlier this week about a situation regarding a newly installed VMware vCenter Server Appliance 6.5U1 and was looking for an explanation, which is why this blog post is created. It's just an information about my findings. I was setting up a new vCSA 6.5U1 recently and discovered… Continue reading [INFO] vCSA 6.5U1 timesyncd fallback servers
