Description

The Add-CauClusterRole cmdlet adds the Cluster-Aware Updating (CAU) clustered role that provides the self-updating functionality to the specified cluster. When the CAU clustered role has been added to a cluster, the failover cluster can update itself on the schedule that is specified by the user, without requiring an external computer to coordinate the cluster updating process.

To run this cmdlet, Windows PowerShell® remoting must be enabled on each node. To do this, run 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: Add a CAU clustered role on the specified cluster at a specific interval

$parameters = @{
    ClusterName = 'CONTOSO-FC1'
    DaysOfWeek = 'Tuesday',
                    'Saturday'
    WeeksOfMonth = '2',
                    '4'
    MaxFailedNodes = '2'
    MaxRetriesPerNode = '2'
    PostUpdateScript = '\\CONTOSOFileShare\scripts\verifyupdatesinstalled.ps1'
    RequireAllNodesOnline = $true
    EnableFirewallRules = $true
    Force = $true
}
Add-CauClusterRole @parameters

This command adds the CAU clustered role, using a default name, on the cluster called CONTOSO-FC1. The CAU clustered role is configured to perform Updating Runs on Tuesdays and Saturdays on the second and fourth weeks of each month. In an Updating Run, the maximum number of failed nodes is two and the maximum number of retries per node is two. A script called verifyupdatesinstalled.ps1 runs on each node after it has been fully updated. Before an Updating Run can begin, all the nodes of that cluster must be running. If it isn't already enabled, the Remote Shutdown Windows Firewall rule group will be enabled on each cluster node. Because the command uses 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: Add a CAU clustered role on the specified cluster at a specific interval

$parameters = @{
    ClusterName = 'CONTOSO-FC1'
    DaysOfWeek = 'Tuesday',
                    'Saturday'
    IntervalWeeks = '3'
    MaxFailedNodes = '2'
    MaxRetriesPerNode = '2'
    EnableFirewallRules = $true
    Force = $true
}
Add-CauClusterRole @parameters

This command adds the CAU clustered role, using a default name, on the cluster called CONTOSO-FC1. The CAU clustered role is configured to perform Updating Runs on Tuesdays and Saturdays at an interval of every three weeks. In an Updating Run, the maximum number of failed nodes is two and the maximum number of retries per node is two. Updating Runs can begin even when the nodes of the cluster aren't all running (if the cluster itself has quorum and is running). If it isn't already enabled, the Remote Shutdown Windows Firewall rule group will be enabled on each cluster node. Because the command uses 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: Add a CAU clustered role on the specified cluster using plug-ins

$parameters = @{
    ClusterName = 'CONTOSO-FC1'
    CauPluginName = 'Microsoft.WindowsUpdatePlugin',
                    'Microsoft.HotfixPlugin'
    CauPluginArguments = @{'IncludeRecommendedUpdates' = 'True'},
                         @{'HotfixRootFolderPath' = '\\CauHotfixSrv\shareName'}
    StopOnPluginFailure = $true
    EnableFirewallRules = $true
    Force = $true
}
Add-CauClusterRole @parameters

This command adds the CAU clustered role, using a default name, on the cluster called CONTOSO-FC1. The CAU clustered role is configured to perform updates using the Microsoft.WindowsUpdatePlugin plug-in with the optional IncludeRecommendedUpdates parameter set to True, and using the Microsoft.HotfixPlugin plug-in using the hotfix root folder \\CauHotfixSrv\shareName and the default hotfix configuration file. If a failure occurs during the installation of updates on a node by Microsoft.WindowsUpdatePlugin, updates are applied by Microsoft.HotfixPlugin plug-in. If it isn't already enabled, the Remote Shutdown Windows Firewall rule group is enabled on each cluster node. Because the command uses 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.

Parameters

-AttemptSoftReboot

Indicates that the CAU clustered role attempts a Kernel Soft Reboot (KSR) for the failover cluster.

KSR bypasses BIOS/firmware initialization. You can only use KSR for updates that do not require a BIOS/firmware initialization.

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

-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 Cluster-Aware Updating plug-ins work.
Type:Hashtable[]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-CauPluginName

Specifies one or more plug-ins to use when performing scans or updates. You can specify multiple values separated with commas. The default is the Microsoft.WindowsUpdatePlugin plug-in. This plug-in coordinates the Windows Update Agent software resident on each cluster node, the same software that is used when updates are downloaded from Windows Update or Microsoft Update, or from a Windows Server Update Services (WSUS) server. For more information about how plug-ins work with CAU, see How CAU Plug-ins Work.

Type:String[]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ClusterName

Specifies the name of the cluster on which to create the CAU clustered role. This parameter is only required when this cmdlet isn't run on a failover cluster node, or this cmdlet is used to reference a failover cluster different from where the cmdlet is run.

Type:String
Position:0
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ConfigurationName

Specifies the Windows PowerShell session configuration that defines the session in which scripts, specified by the PreUpdateScript and PostUpdateScript parameters, and cmdlets are run, and can limit the cmdlets that are available to be run. If either a pre-update or post-update script is specified but a configuration name is not specified, then the default session configuration that is built into Windows PowerShell is used.

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

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf

Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Credential

Specifies the administrative credentials for the target cluster.

Type:PSCredential
Position:1
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-DaysOfWeek

Specifies the days of the week on which the updating task will be triggered. Multiple values can be specified either separated with commas or as a hexadecimal sum.

The acceptable values for this parameter are:

  • Sunday or 0x01
  • Monday or 0x02
  • Tuesday or 0x04
  • Wednesday or 0x08
  • Thursday or 0x10
  • Friday or 0x20
  • Saturday or 0x40
Type:Weekdays
Accepted values:None, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-EnableFirewallRules

Indicates that the cmdlet enables the Remote Shutdown Windows Firewall rule group on each cluster node, if it isn't already enabled. If the EnableFirewallRules parameter is specified, CAU will also automatically re-enable the Remote Shutdown rule group each time the CAU clustered role performs an Updating Run, in case the rules are disabled manually in the intervening time. Enabling this rule group permits inbound communication to each cluster node during each Updating Run that allows CAU to shut down and restart the node remotely (if the installation of an update requires a restart). If Windows Firewall is in use on the cluster nodes and the rule group isn't enabled, the Updating Run will fail. The Remote Shutdown Windows Firewall rule group isn't enabled when it will conflict with Group Policy settings that are configured for Windows Firewall.

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

-FailbackMode

Specifies the method used to bring drained workloads back to the node, at the end of updating the node. Drained workloads are workloads that were previously running on the node, but were moved to another node.

The acceptable values for this parameter are:

  • NoFailback
  • Immediate
  • Policy

The default value is Immediate.

Type:FailbackType
Accepted values:NoFailback, Immediate, Policy

Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ForcePauseAndDrain

Indicates that the CAU cluster role forces cluster nodes to pause and drain roles.

A forced drain moves the roles off of the draining node even if the group cannot move. A group might not be able to move because no other node can host the group or the group is locked.

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

-ForcePauseDrainAndReboot

Indicates that the CAU cluster role forces cluster nodes to pause, drain roles, and restart.

A forced drain moves the roles off of the draining node even if the group cannot move. A group might not be able to move because no other node can host the group or the group is locked.

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

-ForcePauseNoDrain

Indicates that the CAU cluster role forces cluster nodes to pause. The nodes are not drained.

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

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-MaxFailedNodes

Specifies the maximum number of nodes on which updating can fail. If one more than this number of nodes fails, then the Updating Run is stopped. The range is from 0 through 1, less than the number of cluster nodes. The default for most clusters is approximately one-third of the number of nodes.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-MaxRetriesPerNode

Specifies the maximum number of times that the update process attempts to run. This includes any pre-update and post-update scripts. The update process is retried per node. The maximum is 64 and the default is 3.

Type:Int32

Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-PostUpdateScript

Specifies the path and file name for a Windows PowerShell script to run on each node after updating finishes, and just after the node is brought out of Maintenance mode. The file name extension must be .ps1 and the total length of the path plus the file name must be no longer than 260 characters. As a best practice, the script should be located on a disk in cluster storage, or at a highly available network share, to ensure that the script is always accessible to all the cluster nodes.

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

-PreUpdateScript

Specifies the path and file name for a Windows PowerShell script to run on each node before updating begins, and before the node is put into Maintenance mode. The file name extension must be .ps1 and the total length of the path plus the file name must be no longer than 260 characters. As a best practice, the script should be located on a disk in cluster storage, or at a highly available network share, to ensure that the script is always accessible to all the cluster nodes. If a pre-update script fails, the node isn't updated.

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

-RebootMode

Specifies the type of reboot to use for each node in the cluster during the update. The available values are:

  • ClusProp
  • FullReboot
  • SoftReboot
  • PluginCustomReboot
  • OrchestratorDefault
Type:RebootType
Accepted values:ClusProp, FullReboot, SoftReboot, PluginCustomReboot, OrchestratorDefault
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-RebootTimeoutMinutes

Specifies the time in minutes that CAU allows for the restarting of a node. If the restart doesn't complete within this time, then the Updating Run on that node will be marked as failed.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-RequireAllNodesOnline

Indicates that the cmdlet enforces that all cluster nodes are online and reachable before updating begins.

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

-RunOnce

Specifies that the CAU run should only be performed once, rather than on a recurring schedule. This can be useful if you only need to perform a one-time update of your cluster nodes.

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

-RunPluginsSerially

Indicates that the cmdlet CAU scans each cluster node for applicable updates and stages the updates for each plug-in in the plug-in order when multiple plug-ins are used during an Updating Run when you use the CauPluginName parameter. 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 this cmdlet shuts down CAU and restarts 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. By default, during an updating run, all plug-ins complete the installation of updates on a cluster node before the node restarts one time.

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

-SiteAwareUpdatingOrder

Specifies the order in which the CAU cluster role updates cluster nodes.

By default, CAU selects the order of nodes to update based on the level of activity.

Type:String[]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-SkipUpdateChecks

Indicates that the CAU cluster role skips update checks.

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 this cmdlet coordinates subsequent updates on the node when plug-ins are stopped. When multiple plug-ins are used during an updating run, by default, a failure by one plug-in doesn't affect the application of updates on a node by other plug-ins. This 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

-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. The retries for this error don't count towards 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.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-VirtualComputerObjectName

Specifies the name of a pre-staged virtual computer object that is used by the CAU clustered role. For more information, see Steps to create computer objects in Active Directory. If not specified, then a virtual computer object is created using a generated name. Generating a name automatically requires the cluster name object to have permissions to create the virtual computer object in Active Directory.

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

-WarnAfter

Specifies the time in minutes after which a warning will be logged if the Updating Run (including any pre-update and post-update scripts) hasn't completed. By default, no warning will be logged, regardless of the time taken by the Updating Run.

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

-WeeksOfMonth

Specifies the weeks of the month when the Updating Run should be run. The value 5 represents the last week of the month.

Type:Int32[]
Position:Named
Default value:None
