VMware NSX-T – Modifying the Default Admin Password Expiration

Reading Time: < 1 minute

In NSX-T, the Admin and Audit user passwords for both the NSX Manager and NSX Edge appliances expire, by default, after 90 days. When these passwords expire, you will not be able to log in and manage your NSX-T components. This includes any API calls where administrative credentials are required.

In this article I detail the simple process of amending the expiration period or, if so required, removing the password expiration altogether (the latter being perfect for POC and/or lab environments).

North East England VMUG – 26th September 2019

Reading Time: 4 minutes

That didn’t disappoint! I’ve wanted to visit the North East England VMUG for sometime, so being asked to present at the user group made it all the more special. As I sit here in Newcastle International Airport waiting for my flight home, I thought I’d summarise the event for those who’ve never been to a VMUG event, are thinking of doing so in the future, or are thinking of speaking at a local VMUG.

Deploying vSAN with vCenter Server Appliance

Reading Time: 11 minutes

vSAN deployments in brownfield environments are simple. New hosts are configured based on projected workloads (plus points for utilising vSAN Ready Nodes), they’re purchased, racked, built, and absorbed into an existing vCenter workload domain before vSAN is finally enabled and configured. But how would we deploy vSAN into a greenfield environment? An environment with no vCenter, no shared storage, but only brand new ESXi hosts with valid (yet unconfigured) cache and capacity vSAN disks? As vSAN is reliant on vCenter for its operations, we seemingly have a chicken-and-egg scenario.

In this article, I detail the process of deploying (Stage 1) and configuring (Stage 2) a vCenter Server Appliance into a greenfield environment and, more specifically, onto a single-node vSAN cluster in hybrid-mode (Note – this is in no way supported by VMware for anything other than deploying vCenter and vSAN into a greenfield environment). I then add additional hosts to the cluster and configure vSAN storage and networking via the brilliant Cluster Quickstart tool (Stage 3), before applying a vSAN VM Storage policy to the vCenter Server Appliance (Stage 4). Once complete, our vSAN cluster will be ready to host live workloads.

The Next Chapter…

Reading Time: 2 minutes

After almost six years at the Royal College of Nursing (the last two and a half as Senior Infrastructure Architect) the time has come to move on to pastures new. I’ve loved working with such a talented team of professionals (David Collins, Wayne Shadrach, Richard Thompson, Mark Whalley, and Darren Latter), and the leadership of Geoff Lewis (Technical Operations Manager) and Huw Bevan (IT Operations Manager) has been an inspiration since day one.

I’ve been lucky enough to have led on a number of exciting projects over the years, and my sincerest thanks to all at the RCN for the opportunities, the friendships (which don’t end here), and the amazing memories.The RCN will always hold a special place in my heart.

North East England VMUG – 26th September 2019

Reading Time: 2 minutes

The next North East England VMUG will be taking place on Thursday 26th September at the Royal Station Hotel, Newcastle, and I’m excited to be presenting alongside so many fantastic individuals from throughout the vCommunity.

My session will be covering VMware NSX Data Centre for vSphere (NSX-V) and, more specifically, a real world look at micro-segmentation and the implementation of a zero-trust environment. NSX makes this fairly easy thanks to a number of built-in tools, and we’ll explore how we can use the NSX Application Rule Manager to visualise application dependencies in order to start fleshing-out our Distributed Firewall rules.

VMware vCenter Server Appliance – Reset Lost, Forgotten or Expired Root Password

Reading Time: 2 minutes

Patching my lab’s vCenter Server Appliance this evening raised an issue whereby the root password had expired. Unable to login via root, I can still administer the appliance via a vCenter’s SSO domain account (administrator@vsphere.local, for instance), however, attempts to perform any updates will not be possible until the appliance’s root account password is reset. This an easy exercise, however, this is not possible via vSphere UI or console, only bash.

VMware NSX Data Center for vSphere (NSX-V) – Dynamic Routing via OSPF

Reading Time: 8 minutes

VMware NSX Data Center for vSphere (NSX-V) has been able to leverage dynamic routing via Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP) for some time and, in this article, I detail the process of configuring OSPF on both an Edge Services Gateway (ESG) and a downstream Distributed Logical Router (DLR).

OSPF, a Link State Protocol and member of the Interior Gateway Protocol (IGP) family (which also includes Routing Information Protocol (RIP), Intermediate System to Intermediate System (IS-IS), and Enhanced Internal Gateway Routing Protocol (EIGRP)), enables all participating routers to dynamically exchange network topology information to calculate the best shortest path (cost) of a route’s destination.

VMware vExpert 2019 – Second-Half Applications Now Open

Reading Time: < 1 minute

Twice each year VMware’s vExpert program opens its doors to applications throughout the IT and tech community. That second door opened just recently on June 7th 2019. The vExpert community is a group of like-minded enthusiasts, bloggers, book authors, VMUG leaders, speakers, tool builders, and community leaders.

If you are already busy in the community and are contributing in some way, this will without doubt open doors for you, give you priority access to VMware information and, of course, there are the usual vExpert licensing benefits.This has opened a huge amount of doors for me over the past two years, and has been a key driver in forming a number of fantastic relationships and creating some amazing opportunities. In my eyes, the VMware community in general is the most amazing community out there. Full of amazing, knowledgeable people, so why not join in?
