Set-VMHostFirmware

This cmdlet configures hosts firmware settings. If the BackupConfiguration parameter is set, backups the host configuration and downloads the bundle to the specified DestinationPath. In order to use the Restore and ResetToDefaults parameters, the host needs to be in maintenance mode. The Backup functionality of Set-VMHostFirmware is deprecated and scheduled for removal. For making backups, use the Get-VMHostFirmware cmdlet instead.

    Examples

    Example 1

    Set-VMHost -VMHost Host -State 'Maintenance'
    Set-VMHostFirmware -VMHost Host -Restore

    Restore the host firmware by using the default path for the firmware bundle. You can store the bundle to the default path through HTTP by using the upload URL specified in the firmware bundle object:

    Example 2

    Set-VMHost -VMHost Host -State 'Maintenance'
    Set-VMHostFirmware -VMHost Host -Restore -SourcePath c:\bundleToRestore.tgz -HostUser user -HostPassword pass

    Restore the host firmware by specifying a firmware bundle as a source path.

    Example 3

    Set-VMHost -VMHost Host -State 'Maintenance'
    Set-VMHostFirmware -VMHost Host -ResetToDefaults

    Reset the host configuration to the factory default settings.

    Example 4

    Get-VMHostFirmware -VMHost Host1, Host2 -BackupConfiguration -DestinationPath c:\StoredBundles
    Set-VMHost -VMHost Host1, Host2 -State 'Maintenance'
    Get-VMHost -Name Host1, Host2 | Set-VMHostFirmware -Restore -SourcePath c:\StoredBundles -HostUser user -HostPassword pass

    Restore multiple hosts firmware by specifying the firmware bundle as a source path directory. The command determines which bundle is needed for each host by the bundle name.
