A “power supply down” alert on a hyperconverged node looks alarming, and it’s tempting to treat it as a straightforward parts failure: pull the PSU, rack a new one, move on. But that instinct can send you chasing the wrong fix. PSUs fail on their own often enough, but they can also report the exact […]

Before anything else: if you suspect a drive has failed, open a case with Nutanix Support straight away. Don’t pull a disk on your own judgement. Support will confirm the drive has genuinely failed rather than been marked offline for another reason, identify the correct physical slot, dispatch the replacement, and — importantly — check […]

Before anything else: if you are not certain what a task is doing, contact Nutanix Support before you touch it. What follows edits the cluster’s task database directly. It is an advanced troubleshooting procedure, not routine housekeeping, and the wrong task aborted at the wrong moment can leave an operation half-finished with no record that […]

Sooner or later on a Lenovo ThinkAgile HX cluster you’ll need to get into the XClarity Controller and find that nobody knows the password. The person who racked the nodes has left, the credentials never made it into the password manager, or a security review has just told you the default USERID account needs rotating. […]

Controller VM memory is one of those settings that gets chosen once, at deployment, and then quietly stops being right. The cluster grows, you enable a few more services, VM count creeps up — and one morning Prism raises a critical alert telling you RAM usage on a CVM is high. The good news is […]

This one turns up on almost every Prism Central deployment eventually: a warning alert saying disk space usage for /home/log/audit has exceeded 75%. It looks alarming — a full filesystem on the management plane is not something you want to ignore — but in most cases it’s routine housekeeping rather than a fault. The audit […]

A full cluster shutdown isn’t something most Nutanix admins do often, which is exactly why it goes wrong when it’s needed — a data centre power maintenance window, a planned electrical cutover, a physical move. Unlike a single node reboot or an LCM upgrade, there’s no wizard walking you through it: you’re stopping every guest […]

Every so often an LCM firmware upgrade doesn’t come back. The node was booted into Phoenix — the small Linux environment LCM uses to flash firmware — the update failed or stalled partway, and now the node is sitting at a Phoenix prompt with its CVM and hypervisor both in maintenance mode. Prism shows a […]

Nutanix Cloud Clusters (NC2) on Azure comes up in almost every hybrid-cloud conversation I have now, and most of the time the person asking has a slightly wrong picture of it — either as “Nutanix hosting” or as “a VM service in Azure.” It’s neither. This is a plain explanation of what it actually is, […]

If you run workloads on Azure VMware Solution (AVS) using the SKUs that come with VMware licences included, you have a deadline you may not have planned for. Microsoft is retiring the licence-included version of AVS: sales stop on 31 October 2026, and existing environments on those SKUs must be transitioned by 30 August 2027. […]

Upgrading a Nutanix cluster is one of those jobs that looks intimidating the first time and routine the tenth. Life Cycle Manager (LCM) does most of the heavy lifting — dependency resolution, rolling reboots, VM evacuation — but the order you do things in, and what you check before you press Apply, is still on […]

Running VMs and containers on separate platforms costs more than it looks. A read of the latest Nutanix infographic on consolidating both onto a single, future-ready platform.
