Let’s be honest — keeping a fleet of Ubuntu servers updated isn’t the most glamorous job, especially when they’re tucked away behind firewalls with no internet access. But what if we could turn this dusty chore into a clean, elegant, and even satisfying little automation adventure? That’s exactly what we did. This was actually my first real project using Ansible, and it turned out to be a fantastic way to
Dell’s Integrated Dell Remote Access Controller (iDRAC) is an essential tool for managing Dell PowerEdge servers remotely. However, losing access due to a forgotten password can be a challenge. If you have ESXi installed on your server, you can reset the iDRAC password directly from the ESXi shell using the RACADM tool. This guide walks you through the process step by step. Prerequisites Before proceeding, ensure that: Using the RACADM
Recently, I encountered an issue where I was unable to access the vCenter web interface in my Test-Lab, after restoring to a pretty old Snapshot. Upon attempting to log in, I was met with the errors “No healthy upstream” and “503 – Service Not Available” on the management interface. This blog post outlines how I debugged and resolved this issue, which turned out to be caused by an expired certificate.
Managing a vCenter environment with multiple Datacenters and Clusters can quickly become a complex and time-consuming task, especially when dealing with repetitive operations like adding or renaming Datastores. Inconsistent naming conventions, manual errors, and scalability challenges often complicate matters further. Automation offers a powerful solution. By leveraging PowerShell scripts tailored for vCenter, you can simplify routine tasks, enforce consistency, and significantly reduce the risk of human error. In this post,
Accidentally deleting a datastore in a VMware ESXi environment can feel like a catastrophic event, especially when the datastore is shared across multiple hosts. In this article, we’ll discuss the step-by-step process of recovering a deleted datastore, specifically when it was removed from one ESXi host and subsequently disappeared from all associated hosts. The goal is to help you understand the available recovery options and ensure data is restored with
