Enabling SSH on ESXi with vRO

I think it is a good rule of thumb that the security maturity of the organisation can be measured by whether SSH is left enabled (with warnings muted) or disabled on ESXi Hosts. As there is a warning on the host if the service is enabled, and the hardening guides recommend that it is disabled,… Read More »

Reporting on vSphere Replication transfer sizes

vSphere Replication is really a wonderful product – I’ve been using it for a few years now across a few employers and I’ve never had a really serious problem with it – it just seems to work. Sure, there are a few feature requests we could make of it, for example setting a schedule of… Read More »

Updating a HP iLO using Rest API and vRealize Orchestrator

A security vulnerability against Hewlett Packard iLOs was announced last year (link – https://www.rapid7.com/db/modules/auxiliary/admin/hp/hp_ilo_create_admin_account), along with the required firmware to patch. No doubt there are some amazing tools by HP that will allow firmware to be patched across an estate, but as I don’t have access to them I need to find another way to… Read More »

One of the main issues that face departments on their virtualisation journey is how they are managing snapshots: Who can take them Who can delete them How long do they stick around for Name/Description formatting policy I consider them ‘low hanging fruit’ on the management tree – how an organisation approaches this is defined by… Read More »

Detach old ESXi installation devices

When clearing up host storage, you might sometimes encounter an error when you come to detach a device. The cause of this can be an old ESXi installation and you’ll need to erase the ESXi partitions in order to detach old ESXi installation devices. The typical use case for this is reclaiming SAN boot LUNs… Read More »

vRealise Log Insight and Orchestrator

I’m a big fan of the vRealize suite as it really adds value to a vSphere deployment. In relation to this post, LogInsight is a great tool for providing log analysis and Orchestrator manages workflows to automate and orchestrate most/all of the infrastructure. A series of posts  on vmware.com – “Self Healing Datacenter” – have… Read More »

Detaching Devices from a Cluster

When working with block storage we occasionally need to remove a storage device from the hosts it is connected to. When using the Web Client we can detach devices on a per-host basis, but there is nothing to detach from all its attached hosts. What we do have is a helpful KB article on how… Read More »

vSphere REST API and C++ (Part 2)

This is the second part in an ongoing series looking at using the vSphere REST API and C++ with the cpp rest sdk (formerly known as “Casablanca”). In the first part we authenticated against SSO and got some information from the vCenter. In this part we are going to refine our methods so that we… Read More »
