On-Demand session URLs for VMware Explore US 2023

by // 4 Comments

VMware Explore 2023 has officially concluded! Thank you to all the customers, partners and colleagues that I had a chance to connect with during the conference. While I was not able to attend as many breakout sessions as I had planned, all sessions are recorded and are available in VMware Explore Video Library for 2023.

Just like in past years, I have put together a small Github page that simply summarize all VMware Explore US 2023 breakout sessions by their Category, Session Code, Session Name, On-demand URL, Presentation, Views and Session Speakers. This should make it very easier to search for a specific session, topic or speaker and jump straight to the VMware Explore on-demand link, which will require a VMware Explore account to view the session. There are no offline viewing options, you must login to view the content from the VMware Explore site.

UPDATE (11/09/23) - The initial sessions for Explore Barcelona have just been published, as more sessions are added, I will update the repo.

How to check the number of days before ESXi password expires?

by // 4 Comments

Local user accounts created in ESXi including the root user has a default password expiration of 99999 days before administrators need to change the password. Users can control the password expiry by modifying the following ESXi Advanced Setting called Security.PasswordMaxDays which is also referenced in the ESXi Security Documentation along with other advanced configurations.

Password rotation or updates are typically managed by an organizations password management solution which is responsible keeping track and notifying when local passwords are about to expire. With that said, not everyone has a password management solution and how do you quickly check how many days left before an account password expires on an ESXi host? I initially thought this should be pretty simple to figure out, especially with utilities like chage but the version that ESXi ships is a stripped down version via Busybox and it did not provide any expiry details like the typical chage version might.

This meant, that the password expiry would need to be calculated manually and luckily, this is not a new concept. The answer lies in the /etc/shadow file which contains a number of fields that can then be used to figure out the number of days left before an account expires or if has already expired. I will not bore you with the details, but you can create the following shell script which can run in the ESXi Shell to provide you with the answer.

How to relocate an existing vSphere Content Library from one vSphere Datastore to another?

by // 9 Comments

When you create a vSphere Content Library using vCenter Server, the content library is comprised of both the raw uploaded files (OVF, OVA, VM Templates, ISO, etc) which are stored in a vSphere Datastore and the metadata that is generated by vCenter Server for the individual files, which are stored in the vCenter Server Database (VCDB). In contrast, when an External vSphere Content Library is created, which can be backed by any HTTP(s) endpoint, both the metadata along with the raw files are stored external to the vCenter Server and is managed separately.

Today, there is not an easy way to relocate or move an existing vSphere Content Library from one vSphere Datastore to another. The process would require creating a new vSphere Content Library, then manually using either the vSphere UI or API to then copy all the files from the previous content library to the newly created one which is backed by a different vSphere Datastore.

Typically, the reason for this use case is either you are running out of storage and can not expand further or you need to decomission the underlying storage backing the content library.

Recently, I needed to look into this for my own homelab setup where I plan to rebuild one of my setup which is running on vSAN and I wanted to preserve existing content library without having to transfer content back/fourth. The context above was important as I was able to figure out this could be done with some minor tweaks to the VCDB (which I typically do not recommend touching for this reason) but for this purpose, it really is the only way which I had also confirmed with Engineering.
