PowerCLI for VAAI disable

[jessem]

Hi,

I know this one should be easy but wondering how I could script this on a cluster?

Disabling VAAI using vSphere CLI or PowerCLI

To disable VAAI using the vSphere CLI:

Note: Ensure that the vSphere CLI (vCLI) is installed and is able to connect to the ESXi/ESX hosts. For more information, see the vSphere Command-Line Interface Installation and Scripting Guide.

1. Run these vicfg-advcfg commands to change the three settings:
   
   vicfg-advcfg connection_options -s 0 /DataMover/HardwareAcceleratedMove
vicfg-advcfg connection_options -s 0 /DataMover/HardwareAcceleratedInit
vicfg-advcfg connection_options -s 0 /VMFS3/HardwareAcceleratedLocking
   
   Note: For more information and examples on using vCLI connection options, see the Common Options for vCLI Execution section of the vSphere Command-Line Interface Installation and Scripting Guide.
   
   
2. Repeat this process for all the ESXi/ESX hosts connected to the storage as no reboot is required. For a production environment, ensure that you plan accordingly.

To disable VAAI using the PowerCLI:

• Run the command:
  
  Set-VMHostAdvancedConfiguration -VMHost Hostname -Name OptionName -Value 0
  
  Where OptionName is one of:
  
  
  • DataMover.HardwareAcceleratedMove
  • DataMover.HardwareAcceleratedInit
  • VMFS3.HardwareAcceleratedLocking
  For example:
  
  Set-VMHostAdvancedConfiguration -VMHost (Get-VMHost ($Hosts.SelectedItem)) -Name DataMover.HardwareAcceleratedMove -Value 0

Set-VMHostAdvancedConfiguration -VMHost (Get-VMHost ($Hosts.SelectedItem)) -Name DataMover.HardwareAcceleratedInit -Value 0

Set-VMHostAdvancedConfiguration -VMHost (Get-VMHost ($Hosts.SelectedItem)) -Name VMFS3.HardwareAcceleratedLocking -Value 0

And how could I check to see if it ran successful against a list of hosts....output to a csv or something?

To change the value on all ESXi in a cluster, you can do something like this

$clusterName = "MyCluster"

Get-Cluster -Name $clusterName | Get-VMHost |

Get-AdvancedSetting -Name DataMover.HardwareAcceleratedMove |

Set-AdvancedSetting -Value 0 -Confirm:$false

And to produce a report you could do

Get-Cluster -Name $clusterName | Get-VMHost |

Get-AdvancedSetting -Name DataMover.HardwareAcceleratedMove |

Select Entity,Name,Value |

Export-Csv report.csv -NoTypeInformation -UseCulture

The first change "DataMover.HardwareAcceleratedMove" worked.  However, the other 2 settings, DataMover.HardwareAcceleratedInit and Locking did not....this isn't right, is it?

$clusterName = "VMLAB 01"

Get-Cluster -Name $clusterName | Get-VMHost |

Get-AdvancedSetting -Name DataMover.HardwareAcceleratedMove |

Set-AdvancedSetting -Value 0 -Confirm:$false

Get-AdvancedSetting -Name DataMover.HardwareAcceleratedInit |

Set-AdvancedSetting -Value 0 -Confirm:$false

Get-AdvancedSetting -Name VMFS3.HardwareAcceleratedLocking |

Set-AdvancedSetting -Value 0 -Confirm:$false

If you want to set all 3 settings in the script you should something like this

$clusterName = "MyCluster"

Get-Cluster -Name $clusterName | Get-VMHost | %{

   Get-AdvancedSetting -VMHost $_ -Name DataMover.HardwareAcceleratedMove | Set-AdvancedSetting -Value 0 -Confirm:$false

   Get-AdvancedSetting -VMHost $_ -Name DataMover.HardwareAcceleratedInit | Set-AdvancedSetting -Value 0 -Confirm:$false

   Get-AdvancedSetting -VMHost $_ -Name VMFS3.HardwareAcceleratedLocking | Set-AdvancedSetting -Value 0 -Confirm:$false

}

You keep the ESXi host in the pipe variable ($_) and call the sequence for each of the variables.

Or you could also do

$clusterName = "MyCluster"

$advSettings = "DataMover.HardwareAcceleratedMove","DataMover.HardwareAcceleratedInit","VMFS3.HardwareAcceleratedLocking"

Get-Cluster -Name $clusterName | Get-VMHost |

Get-AdvancedSetting -Name $advSettings |

Set-AdvancedSetting -Value 0 -Confirm:$false

The second option worked flawlessly.  So now then, what should my new output to csv be to get all the options listed for all the hosts in my cluster?

[LucD]

Something like this

$clusterName = "MyCluster"

$advSettings = "DataMover.HardwareAcceleratedMove","DataMover.HardwareAcceleratedInit","VMFS3.HardwareAcceleratedLocking"

Get-Cluster -Name $clusterName | Get-VMHost |

Get-AdvancedSetting -Name $advSettings |

Select Entity,Name,Value |

Export-Csv report.csv -NoTypeInformation -UseCulture

Thanks!  Worked like a champ!
