How to revert an ESXi host to a previous version using DCUI

This video demonstrates how to revert an ESXi host to a previous version using the Direct User Console Interface (DCUI).

VMware recommends that you back up the configuration data before proceeding with any changes.

Reverting an ESXi host is only available if the host was updated using one of the following methods:

  • VIB installation or removal
  • Profile installation or removal
  • ESXi host updated using VMware Update Manager
  • ESXi host updated from a ISO

Purging old data from the vCenter Server database

This video demonstrates how to purge old data from the SQL Server database used by vCenter Server. You would need to perform task if your vCenter database is full.

When the vCenter Server database if full:

  • You cannot log in to vCenter Server
  • VMware VirtualCenter Server service may start and stop immediately.

To resolve this issue, we need to manually purge or truncate the vCenter Server database. Details of how to do this and the script to truncate the database is documented in KB article: Purging old data from the database used by vCenter Server (1025914)

Updating patches on an ESXi host using “esxcli software vib” commands

This video demonstrates how to update patches on an ESXi 5.x/6.x host using “esxcli software vib” commands. Patches can either be installed or updated on an ESXi host using esxcli vib commands.

Caution: The install method has the possibility of overwriting existing drivers. If you are using third-party ESXi images, VMware recommends using the update method to prevent an unbootable state.

Patches for VMware products can be downloaded from the following location

How to backup and restore the embedded vCenter Server 6.0 vPostgres database

This video demonstrates how to backup and restore an embedded vCenter Server 6.0 vPostgres database. Backing up your database protects the data stored in your database. Of course, restoring a backup is an essential part of that function.

This follows up on our recent blog & video: How to backup and restore the embedded vCenter Server Appliance 6.0 vPostgres database

Note: This video is only supported for backup and restore of the vPostgres database to the same vCenter Server. Use of image-based backup and restore is the only solution supported for performing a full, secondary appliance restore.

VSAN Troubleshooting Video Series

vmware-vsanVMware Technical Support University is very proud to present our Virtual SAN Troubleshooting Video Series, comprising of 26 bite sized videos- not only covering troubleshooting but also design, requirements, compatibility, and upgrades. These were first presented in the  VSAN trouble shooting webinar that was conducted 27 October, 2016. This video collection, presented by Francis Daly is not to be missed!

***UPDATE: The videos have been moved. They are now part of a free 60-day Trial Subscription of the VMware Learning Zone. You can sign up for that and get access to all these videos (plus lots more) here https://mylearn.vmware.com/mgrReg/courses.cfm?ui=www_edu&a=det&id_course=316802

Troubleshooting “SSO log directory full” in vCenter Server Appliance 6.0

This video demonstrates how to troubleshoot “SSO log directory full” warnings in vCenter Server Appliance 6.0. This is a known issue affecting vCenter Server Appliance 6.0, and currently, there is no resolution. You see that the /storage/log directory is highly utilized in an Embedded vCenter Server Appliance or Platform Controller Server Appliance 6.0.

To work around this issue, reduce the maximum backup size and the maximum backup index in the log4j.properties file.

Note: In external Platform Service Controller (PSC) environments, log in to the Platform Service Controller instead to make the suggested changes.

How to recreate a missing vmdk AKA virtual machine disk descriptor file

This video tells you how to recreate a missing virtual machine disk descriptor, also know as the vmdk file.

Note: VMware recommends to attempt to restore the missing descriptor file from backups if possible. If this is not possible, proceed with recreating the virtual machine disk descriptor file.

Watch the video to see the steps taken to create a virtual machine disk descriptor file:

  • Identify the size of the flat file in bytes.
  • Create a new blank virtual disk that is the same size as the original. This serves as a baseline example that is modified in later steps.
  • Rename the descriptor file (also referred to as a header file) of the newly-created disk to match the name of the original virtual disk.
  • Modify the contents of the renamed descriptor file to reference the flat file.
  • Remove the leftover temporary flat file of the newly-created disk, as it is not required.


This procedure will not work on virtual disks configured with a Para-virtualized SCSI controller in the virtual machine

How to install Windows in VMware Fusion using Easy Install

This video demonstrates how to install Windows guest operating system using the Easy Install feature in VMware Fusion.

Before creating a virtual machine, you must obtain the operating system and any necessary product keys for installation in that virtual machine. VMware Fusion does not come with any operating systems to install in virtual machines you create.

This method assumes that you are using a physical CD or a disk image (.iso / .cdr /.dmg file). You cannot create a Windows virtual machine by using .exe files downloaded from Microsoft, as those files need to be run on a Windows PC.

Troubleshooting Virtual SAN Providers status- Disconnected

This video demonstrates how to troubleshoot Virtual SAN Providers which display the status as disconnected in the vSphere Web Client. This issue occurs if the SMS certificate for vCenter server is expired.

To resolve this issue, expired certificate will be removed and a new certificate will be generated.
