Description

The Set-CauClusterRole cmdlet sets configuration properties for the Cluster-Aware Updating (CAU) clustered role on the specified cluster. This cmdlet can specify properties such as the updating schedule and updating run parameters.

To run this cmdlet with the PostUpdateScript or PreUpdateScript parameters, Windows PowerShell remoting must be enabled on each node. To do this, use the Enable-PSRemoting cmdlet. In addition, ensure that the Windows Remote Management - Compatibility Mode (HTTP-In) firewall exception is enabled on each node.

Examples

Example 1: Configure settings for a CAU cluster role on the specified cluster on the first and second weeks of the month

$parameters = @{
    ClusterName = 'CONTOSO-FC1'
    DaysOfWeek = 'Tuesday'
    WeeksOfMonth = '1,2'
    RebootTimeoutMinutes = '10'
    Force = $true
}
Set-CauClusterRole $parameters

This command configures settings for the CAU clustered role on the cluster named CONTOSO-FC1. The CAU clustered role is configured to perform updating runs on Tuesdays on the first and second weeks of each month. The CAU clustered role allows 10 minutes for the restarting of each node, if a restart is necessary. If the restart doesn't complete within this time, then the updating run on that node is marked as failed. Because the command specifies the Force parameter, the cmdlet runs without displaying confirmation prompts.

This example uses splatting to pass parameter values from the $parameters variable to the command. Learn more about Splatting.

Example 2: Configure settings for a CAU cluster role on the specified cluster on the second week of the month

$parameters = @{
    ClusterName = 'CONTOSO-FC1'
    DaysOfWeek = 'Tuesday'
    WeeksOfMonth = '1,2'
    IntervalWeeks = '2'
    RebootTimeoutMinutes = '10'
    PostUpdateScript = 'c:\verifyupdatesinstalled.ps1'
    Force = $true
}
Set-CauClusterRole $parameters

Name                                                        Value 
----                                                        -----

PostUpdateScript                                            G:\verifyupdatesinstalled.ps1 
RebootTimeoutMinutes                                        10 
DaysOfWeek                                                  Tuesday 
WeeksInterval                                               2

This command configures settings for the CAU clustered role on the cluster named CONTOSO-FC1. The CAU clustered role is configured to perform updating runs on Tuesdays on the second week of each month. The CAU clustered role allows 10 minutes for the restarting of each node, if a restart is necessary. If the restart doesn't complete within this time, then the updating run on that node is marked as failed. The CAU clustered role runs a script after updating completes, just after the node leaves Maintenance mode. The script is located at the root of drive G: in clustered storage and is named verifyupdatesinstalled.ps1. Because the command specifies the Force parameter, the cmdlet runs without displaying confirmation prompts.

This example uses splatting to pass parameter values from the $parameters variable to the command. Learn more about Splatting.

Example 3: Initiate an updating run on the specified cluster

Set-CauClusterRole -ClusterName "CONTOSO-FC1" -UpdateNow -Force

This command causes the CAU clustered role to initiate an updating run immediately on the cluster named CONTOSO-FC1. Because the command specifies the Force parameter, the cmdlet runs without displaying confirmation prompts

Example 4: Configure settings for a CAU cluster role on the specified cluster

$WarnAfter = New-TimeSpan -hour 1 -minute 90 -seconds 10
$StopAfter = New-TimeSpan -hour 2 -minute 90 -seconds 10
$parameters = @{
    ClusterName = 'CONTOSO-FC1'
    WarnAfter = $WarnAfter
    StopAfter = $StopAfter
    StartDate = [DateTime] '1/1/2012'
    Force = $true
}
Set-CauClusterRole @parameters

This example configures settings for the CAU clustered role on the cluster named CONTOSO-FC1. Time spans are specified for logging a warning or canceling the updating run if it isn't completed. The earliest date that an updating run can be triggered is 1/1/2012. Because the command specifies the Force parameter, the cmdlet runs without displaying confirmation prompts

Parameters

-CauPluginArguments

Specifies a set of name=value pairs, as arguments, for each updating plug-in to use. For instance, to specify a Domain argument for one plug-in:

  • @{Domain=Domain.local} You can specify multiple pairs in a set separated with semicolons. For instance:
  • @{name1=value1;name2=value2;name3=value3} These name=value pairs must be meaningful to the CauPluginName parameter that you specify. If you specify arguments for more than one plug-in, provide the sets of name=value pairs in the order that you pass values in CauPluginName, separated by commas. For instance:
  • @{name1=value1;name2=value2;name3=value3},@{name4=value4;name5=value5}

For the default Microsoft.WindowsUpdatePlugin plug-in, no arguments are needed. The following arguments are optional:

  • 'IncludeRecommendedUpdates'='<Value>': Boolean value to indicate that recommended updates will be applied in addition to important updates on each node. If not specified, the default value is False.
  • A standard Windows Update Agent query string that specifies criteria used by the Windows Update Agent to filter the updates that will be applied to each node. For a name, use QueryString and for a value, enclose the full query in quotation marks. If not specified, then the Microsoft.WindowsUpdatePlugin plug-in by default uses the following argument:
  • QueryString="IsInstalled=0 and Type='Software' and IsHidden=0 and IsAssigned=1" For more information about query strings for the default Microsoft.WindowsUpdatePlugin plug-in and the criteria such as IsInstalled that can be included in the query strings, see IUpdateSearcher::Search method.

For the Microsoft.HotfixPlugin plug-in, the following argument is required:

  • HotfixRootFolderPath=<Path>: The UNC path to a hotfix root folder in an SMB share with a structure that contains the updates to apply and that contains the hotfix configuration file

The following arguments are optional for the Microsoft.HotfixPlugin plug-in:

  • RequireSmbEncryption=<Value>: Boolean value to indicate that SMB Encryption will be enforced for accessing data from the SMB share. If not specified, the default value is False. To ensure the integrity of the data accessed from the SMB share, the plug-in requires that the share is enabled for either SMB signing or SMB Encryption.
  • DisableAclChecks=<Value>: Boolean value to indicate that the plug-in will check for sufficient permissions on the hotfix root folder and the hotfix configuration file. If not specified, the default value is False.
  • HotfixInstallerTimeoutMinutes=<Integer>: The length of time in minutes that the plug-in allows the hotfix installer process to return. If not specified, the default value is 30 minutes.
  • HotfixConfigFileName=<name>: Name for the hotfix configuration file. If not specified, the default name DefaultHotfixConfig.xml is used. For more information about required and optional arguments for the Microsoft.HotfixPlugin plug-in, see How CAU Plug-ins Work.

-RunPluginsSerially

Indicates that CAU scans each cluster node for applicable updates and stage the updates for each plug-in in the plug-in order passed into theCauPluginName parameter, when multiple plug-ins are used during an updating run.

By default, CAU scans and stages the applicable updates for all plug-ins in parallel. Regardless of the configuration of this parameter, CAU installs the applicable updates for each plug-in sequentially.

The parameter is valid only when multiple plug-ins are specified in the CauPluginName parameter. If a single plug-in is specified, a warning appears.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-SeparateReboots

Indicates that CAU shuts down and restart a cluster node after each plug-in installs updates on the node, if the installation of an update by a plug-in requires a restart that CAU will shut down and restart a cluster node after each plug-in installs updates on the node, if the installation of an update by a plug-in requires a restart

The parameter is valid only when multiple plug-ins are specified in the CauPluginName parameter. If a single plug-in is specified, a warning appears.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-StartDate

Specifies the earliest date on which the updating run can be triggered.

Type:DateTime
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-StopAfter

Specifies the time in minutes after which the updating run is canceled if it hasn't completed. The time span can be expressed in the standard ways available in Windows PowerShell, for instance, 01:30:00 represents one hour and thirty minutes. By default, the updating run is allowed an unlimited amount of time to complete.

If pre-update or post-update scripts are specified, then the entire process of running scripts and performing updates must be complete within this time limit.

Type:TimeSpan
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-StopOnPluginFailure

Indicates that if a failure occurs during the application of updates on a node by any plug-in, subsequent updates on the node that are coordinated by the remaining plug-ins are stopped when multiple plug-ins are used during an updating run.

The parameter is valid only when multiple plug-ins are specified for the CauPluginName parameter. If a single plug-in is specified, a warning appears.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-SuspendClusterNodeTimeoutMinutes

Specifies the maximum amount of time CAU should wait for the Suspend-ClusterNode cmdlet to succeed if the underlying clustered space is in degraded condition.

If Suspend-ClusterNode fails with ERROR_CLUSTER_SPACE_DEGRADED error, CAU will keep retrying for SuspendClusterNodeTimeoutMinutes or suspend the call if the command succeeds.

These retries don't decrement the value of the MaxRetriesPerNode parameter set by the user.

The timeout value is per cluster node. So CAU could potentially spend the amount of time specified for this value for every node in the cluster in the worst case.
