VMware Virtual Replication – Virtual Machine stays on configuring after datastore migration

We experienced this issue last week, after migrating a replicated VM to a new datastore. We migrated several VMs to faster storage, but there were two with errors related to authentication. The replication kept going fine, but the error didn’t go away. The machine inside the Site Recovery application kept saying: “configuration error. The session is not authenticated”, and the … Read More


Querying a vCenter for mounted ISOs on VMs using PowerCli

As we are retiring datastores that hosts ISOs, some are still in use (or just mounted) on VMs. We can’t take these datastores offline until we figure out which VMs are consuming the datastore just for ISOs. As manually checking is going to take a lot of time, we will just run this via PowerCLI. Start by connecting to PowerCLI … Read More


Using PowerCLI with PowerShell for running scripts on a vCenter

First, we need to disable a few security settings. Start the process by running PowerShell on Admin mode. Run each snippet on the console.   We need to enable TLS 1.2 on PowerShell: [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12   Set the execution policy to run scripts: Set-ExecutionPolicy -ExecutionPolicy Unrestricted   Install the PowerCli module, creating a destination folder for it first: Save-Module -Name … Read More

Pressing ALT + F1 on a remote ESXi console doesn’t bring up the console prompt

Rarely when trying to access a server console via ALT + F1, the server may appear nonresponsive, however, sometimes this is just a false alarm. This is more likely happening when using a KVM device as it may send incorrect characters over. As the VMware documentation mentions:   Connect to the console of the VMware ESX host. At the VMware … Read More


Changing an IP on a backup object in Altaro Backup

On a client we changed the IP addressing on their network and we already had backups in place from Altaro. Altaro didn’t take DNS changes as the vcenter was hardcoded with its IP address. In order to keep the existing chains we needed to change the VMware vCenter IP. In order to change this, we had to download SQL lite browser. … Read More


Adding passthrough disks as RDM on ESXi 6.x

In this example, the client had a need of accessing the disks directly, while sharing a LSI Megaraid controller which was on IT mode. This enabled the controller to have it’s own set of disks in an array, and also 6 disks with 4TB each that were needed as direct disks to the VM. Start by configuring the desired disks … Read More
