Dell PowerProtect Data Manager Setup

In this post, I want to give you a feel for how easy the setup of Dell PowerProtect Data Manager is. 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 […]

PowerCLI Add-VMHost: Unable to verify the authenticity of the specified host

Yep, I also started using PowerCLI more intensively. It’s really fun and makes repeating tasks easier to apply. As a Rookie in whatever you’re starting out with, there are obstacles that you might not be able to explain straight away. So let’s start with something small and I wanted to add an ESX host to my vCenter with the following command: But this failed because […]

vSAN Skyline Health: A possible storage capacity limitation with vSAN OSA versions 8.0U2 and 8.0U2b

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. Anyway, lets try to fix it! 😉 What I really like about vSphere 8 […]

Dell OpenManage Enterprise Darksite Plugin Implementation

I recently had the challenge of retroactively implementing the PowerManager plugin in a dark site for a Dell OpenManage Enterprise Appliance. 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 […]

How to Reset vCenter 8.0 Root Password

Yep, there are still vCenter’s out there with expired root passwords. 😀 Therefore, I will describe the workaround to reset the root password for vCenter 8.0, which also works for vSphere 6.5 through today’s releases. First, take a snapshot of your vCenter VM: Then switch to the ESXi Host Client and open a virtual console from the vCenter VM: Now reboot the vCenter and watch […]

Dell PowerStore Upgrade from 3.2.1 to 3.6 (Dark Site)

Last week I had the challenge of upgrading a Dark Site PowerStore from 3.2.1.0 to 3.6.0.0. PowerStore 3.6 brings a lot of new features, for me there are the following highlights: Starting with the Upgrade BIN file, you will first need to login into your Dell Support account, whereupon you will need to enter the service tag of the PowerStore system. Then filter by operating […]

Dell PowerStore: CPU utilization level too high. Reduce system load prior to NDU. (cpu_usage_level_exceeded)

During a PowerStore Appliance upgrade, one of the most common warnings during a pre-upgrade health check (PUHC) is the message: CPU utilization level too high. Reduce system load prior to NDU: This is a 2-node PowerStore cluster which is to be upgraded from 3.2.x to 3.6.x. The existing checks used to find CPU usage include management and platform CPU cores. As a result, on an idle […]

Because I replaced it with a Dell PowerEdge T430 in November 2023. You can find the documentation of my […]

Dell PowerProtect – Cannot reset CBT while VM has an existing snapshot

In my last backup jobs I noticed in the Dell PowerProtect Data Manager that 1 asset was Completed with Exceptions. The warning was as follows: I have to admit that the warnings and errors in PowerProtect DataManager are mostly self-explanatory and well detailed. We can see that the backup job was successful, but Change Block Tracking (CBT) could not be reset due to an existing […]
