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

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)

This video demonstrates how to update patches on an ESXi 5.x/6.x host using &#rsquo;esxcli software vib&#rdquo; 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 recreate a missing vmdk AKA virtual machine disk descriptor file

 Allgemein, Knowledge Base, Updates, VMware, VMware Partner, VMware Virtual Infrastructure, vSphere  Kommentare deaktiviert für How to recreate a missing vmdk AKA virtual machine disk descriptor file
Okt 212016
 

This video tells youhow 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 on-disk format upgrade to 3.0 failures

 Allgemein, Knowledge Base, Updates, VMware, VMware Partner, VMware Virtual Infrastructure, vSphere  Kommentare deaktiviert für Troubleshooting Virtual SAN on-disk format upgrade to 3.0 failures
Okt 132016
 

This video demonstrates how to troubleshoot Virtual SAN on-disk format upgrade to 3.0, which may fail in small Virtual SAN clusters or ROBO/stretched clusters.

Attempting an on-disk upgrade in certain VSAN configurations may result in failure. Configurations that can cause these errors include:

  • The stretched VSAN Cluster consists of two ESXi Hosts and the Witness Node (ROBO configuration)
  • Each Host in the Stretched Cluster contains a single VSAN Disk Group
  • A Virtual SAN cluster consists of three normal nodes, with one disk group per node
  • A Virtual SAN cluster is very full, preventing the “full data migration” disk-group decommission mode

To allow an upgrade to proceed in these configurations, a compromise as to availability must be made. Data accessibility will be maintained, but the redundant copy of the data will be lost and rebuilt during the upgrade process. As a result, data will be exposed to faults and failures such as the loss of a disk on another node may result in data loss. This exposure to additional failure risk is referred to as “reduced redundancy,” and must be manually specified in the Ruby vSphere Console (RVC) to allow the upgrade to proceed. It is not possible to specify reduced redundancy when using the vSphere Web Client to start the upgrade.

Caution: During upgrade, a single point of failure is exposed. Follow all VMware best practices, and your business practices, regarding the backup of important data and virtual machines.

In this latest KBTV Webinar you will learn some great tips and tricks you can use inRuby vSphere Console (RVC) for managing a Virtual SAN environment.

Covered in this video demonstration are various commands that can be used within Ruby vSphere Console (RVC), including:

  • “vsan.disks_stats” Useful for capacity planning, management of disk groups and monitoring the health of physical disks
  • “vsan.check_state” Useful for troubleshooting data unavailability situations and understanding object health in the VSAN cluster
  • “vsan.resync_dashboard” Useful for visibility into data resync when changing storage policies
  • “vsan.whatif_host_failures” Useful for capacity planning on future VSAN nodes and understanding VSAN’s ability to tolerate node failures

Troubleshooting Virtual SAN 6.2 on disk upgrades which fail after 10%

 Allgemein, Knowledge Base, Updates, VMware, VMware Partner, VMware Virtual Infrastructure, vSphere  Kommentare deaktiviert für Troubleshooting Virtual SAN 6.2 on disk upgrades which fail after 10%
Sep 192016
 

This video demonstrates how to troubleshoot Virtual San 6.2 upgrades which fail after 10% of the upgrade procedure. The resolution provided in this video tutorial will be useful to you if you experience the following symptoms within your VMware Virtual SAN environment:

  • When upgrading VMware Virtual SAN (VSAN) to version 6.2, the Virtual SAN Disk Format Conversion task fails at 10%.
  • In the vSphere Web Client, you see an error similar to:

    A general system error occurred: Failed to realign following Virtual SAN objects, due to being locked or lack of vmdk descriptor file which requires manual fix
  • The Convert disk format for Virtual SAN task fails with a General Virtual SAN error status.

When upgrading the on-disk format, during the 10% – 15% phase, Virtual SAN realigns objects to prepare them for new features. The process is performed in two steps:

        • In the first step, Virtual SAN realigns objects and their components to have a 1 MB address space. The process fails in this step if the cluster is unstable or if there is not enough disk space.
        • In the second step, Virtual SAN realigns vsanSparse objects to be 4k aligned. The process fails if there are objects which cannot be upgraded to version 2.5.

        An object will fail to upgrade under these conditions:

              • The object is left behind and no longer referenced by anything.
              • The disk chain is not complete or is corrupted.

              For additional information, see VMware Knowledge Base article Virtual SAN 6.2 on disk upgrade fails at 10% (2144881).
