In order to succesfully convert Windows systems to a VMware virtual machine, you need to install the sysprep files of the to be converted host. Below is a list of downloads to these sysprep files:

The base folder of where to put the files is always:

Quote
%ALLUSERSPROFILE%\Application Data\VMware\VMware vCenter Converter Standalone\sysprep

Extract contents to: base-folder\2k

Available in SP4 or the CD-ROM of Windows 2000 SP4 at Support\Tools\Deploy.cab

Extract contents to: base-folder\svr2003

A list with direct links to VMware vSphere clients. Saves you a lot of time when you need to (re)install many different versions.

Starting with 6.5, the vSphere client is no longer available.

In VMWare Workstation and vSphere ESX, it is possible to set disks to be independent so they are not linked to snapshots. Independent disks can then be set to be Persistent (changes are written immediately and permanently to disk) or Non-persistent (changes are lost when the VM powers down). In VMWare Fusion, although this option does not seem to be present, it is still available, and can be configured by manually changing the parameters in the VM configuration file (.vmx).

A VM configuration file is a text-based file containing all the parameters and properties for a VM. This file can include options that are not present in the Fusion UI. By adding parameters manually, you can enable featu  ...

A very common practice when setting up SAN storage on a VMWare cluster is to configure the storage path policy to be set to "Round Robin" to properly benefit from MPIO in addition to standard failover. However, if the cluster consists of many nodes or there are many volumes, this can take up quite a lot of time if you configure this using the (Web)GUI. A better way to adjust the setting for the entire cluster is through PowerCLI.

The one-liner:

Get-VMHost <Cluster-or-Host> | Get-ScsiLun -LunType "disk" | Where {$_.MultipathPolicy -ne "RoundRobin"} | Set-ScsiLun -MultipathPolicy RoundRobin

The cmdlet selects a cluster or host, gets all LUNs which are of   ...

I wrote a script to list virtual disk information for a specified VM, including VMDK path, SCSI IDs and more. It is loosely based on this script but excludes all WMI info.

It is possible to install the integration plugins for VMware on an ESX host directly from the Nimble website, provided your hosts have internet access:

  1. Place the host into maintenance mode.
  2. Connect to the host through a shell (e.g. SSH).
  3. Run the command:
    esxcli software vib install -d http://update.nimblestorage.com/esx5/ncm
    Wait for the installation to complete.
  4. Take the host out of maintenance mode and continue with the configuration.

With PowerCLI, you can generate all sorts of lists. To retrieve the configured and reported OS version of your VMs, try running this one-liner:

Get-VM | Sort | 
   Get-View -Property @("Name", "Config.GuestFullName", "Guest.GuestFullName", "Guest.IpAddress") | 
   Select -Property Name, 
       @{N="Configured OS";E={$_.Config.GuestFullName}},
       @{N="Running OS";E={$_.Guest.GuestFullName}},
       @{N="IP Address";E={@($_.Guest.IpAddress)}} | 
   Export-CSV -Delimiter ";" -Path "vms.csv"

If your ESX host has lost connection to the vCenter server, but you can still directly access the host's management, and can find nothing else wrong with the vCenter server or its network connection to the host, you may want to the free space on your ESX host.

Logs and other temporary files may have filled up one or more ramdisk partitions (e.g. when you don't have a persistent scratch partition, it gets mounted on /tmp). This can cause any of the following issues:

Connection loss between the ESX host and vCenter server;

Errors when attempting to reconnect or add an ESX host to a vCenter server;

Errors while attempting to activate or configure HA;

Other unexplainable errors...

If the scratch partition (/tmp) gets filled up, check for the presence of the file ql_ima.log. If it is present, you are bothered by a bug from an older version of the qla4xxx driver. Even if you use Update Manager, this driver does not get updated automatically. The solution is add the driver to Update Manager or download and install the update manually.

This procedure describes the manual installation of the update on your ESX host. There's no need to put the host in maintenance mode but you will have to reboot to use the new driver.

Download the driver (you need a VMware account):

VMware 5.5

VMware 6.0

Unpack the download and copy the file qla4xxx-634.55.28.0-offline_bundle-1682448.z  ...

When deploying a vShield Manager VA, its IP address is set to DHCP by default. Once deployed and started, you can log on through the console to change it to a fixed IP.

Open a VMWare console to the appliance and log on:

manager login: adminPassword: ****** (the CLI 'admin' password you entered during the deployment)

Go into enable mode and enter the setup:

manager> enablePassword: ****** (the enable password you entered during the deployment)manager# setup

Enter the IP address, subnet mask, gateway and DNS settings. When finished, you will be prompted to log out.

Note that after setting the IP address, I had to restart the appliance because the web interface was only accessible on t  ...

Found this interesting read on VMFS Extents and some of the (negative) myths that have arisen over the years:

You can quickly get a list of VMs, the datastores they are using and the logical folder they are in through PowerCLI:

Get-VM | Select Name,@{N="Datastore";E={[string]::Join(',',(Get-Datastore -Id $_.DatastoreIdList | Select -ExpandProperty Name))}},@{N="Folder";E={$_.Folder.Name}}

Combine it with Export-CSV to export the results to a CSV file.

VMWare ESX 5.5 introduces the ability to perform coredumps to a file instead of a partition.

To configure this, you need access to the ESX host's CLI (either through vSphere Management Assistant (vMA), directly on the host through console or SSH, or some other method). For this to work, you need "root" access (or the equivalent of it through vMA).

Once logged on, take a directory listing of the VMFS datastores to determine on which datastore you want to place the coredump files.ls -l /vmfs/volumes

You will see a list of datastore UUIDs as well as symlinks to those UUIDs. Use the symlinked names to figure out which UUID points to which datastore's logical name:For example:

When attempting to unmount or delete a VMFS datastore on a cluster, you may get the message that the resource is still in use, even though all the VMs have been moved off the datastore, or that Storage I/O Control (SIOC) is enabled on it (usually when attempting to unmount).

To circumvent the issue, temporarily stop SIOC, unmount/delete the datastore, then start SIOC again. If an unplanned Permanent Device Loss (PDL) is invoked when Storage IO control enabled on a storage device (iSCSI device or FC), the ESX host cannot remount the VMFS datastore, and also the steps below are then also required in order to be able to remount the datastore.

On each of the ESX hosts (if there's more than one  ...

You can download installation files and ISOs of any of the latest versions of VMWare Tools for each released version of ESX:

https://packages.vmware.com/tools/esx/index.html

This is useful if you need support for a certain OS version but are not able to upgrade the ESX host in order to get it (e.g. Windows 10 support on ESX 5.5 "non-u3").

Note that, although officially unsupported, VMWare Tools is technically backwards compatible, meaning you can install a newer version on a guest running on an older ESX host.

by lunarg on October 6th 2015, at 13:37

Windows 10 is not out of the box supported on ESX 5.5, unless you're running 5.5u3. One of the issues is that earlier versions do not have a compatible video driver for Windows 10.

However, for older versions of ESX 5.5, you can manually download the VMWare Tools and install them:

If your vCenter server has a self-signed certificate, you will get a warning about this when connecting to it from vSphere PowerCLI. You can disable this warning through PowerCLI with the Set-PowerCLIConfiguration cmdlet.

  1. Start an elevated vSphere PowerCLI (right-click, Run as Administrator).
  2. Enter the following cmdlet:
    Set-PowerCLIConfiguration -InvalidCertificateAction Ignore
    Press Enter again to confirm the change.

After making the change, new connections to the vCenter server will no longer produce a warning about the certificate.

When you enable the ESXi Shell or SSH on a particular host in a vSphere cluster, a warning will appear on a ESX host:

ESXi Shell for the host has been enabled

or SSH for the host has been enabled

This is normal behaviour, but you can turn off these warnings for each of the hosts.

Note that prior to vSphere 4.1 Update 2, it is not possible to suppress the warnings.

Open vSphere Client.

Select the ESX host. From the Configuration tab (right pane), click Advanced Settings.

Navigate to UserVars → UserVars.SuppressShellWarning.Set its value to 1.

Click OK to confirm. The warning will disappear immediately.

Log on to vSphere Web Client.

Select vCenter from the Home menu. Select Host  ...

The vSphere Web Client may display the following error:

Failed to verify the SSL certificate for one or more vCenter Server Systems: https://vCenter-Server-FQDN:443/sdk

or

Could not connect to one or more vCenter Server Systems:https://vCenterFQDN:443/sdk

Additionally, objects such as hosts or VMs are not displayed in the vSphere Web Client.

These errors usually occur with a re-installation or upgrade of vCenter Server, where the vCenter Server is registered to the same vSphere SSO more than once.

The faulty registration needs to be resolved by unregistered all duplicate vCenter Server instances from vSphere SSO, so only the correct registrations remain.

You will have to unregister al  ...

The HP Network Config Utility provides advanced network configuration tasks for HP servers. It allows to set up NIC teaming, VLAN and more.

Uninstalling this software (e.g. after a P2V) is not possible through Control Panel (Add/Remove Programs) because it's not in the list like other HP software components. The only way to uninstall HP Network Config Utility is through an NIC's properties:

Open the network properties for any Ethernet NIC (doesn't matter which one).
