Description

The Invoke-CauRun cmdlet performs a scan of cluster nodes for applicable updates and installs those updates through an Updating Run on the specified cluster. The Updating Run process includes the following:

  • Scanning for and downloading applicable updates on each cluster node.
  • Moving currently running clustered roles off each cluster node.
  • Installing the updates on each cluster node.
  • Restarting cluster nodes if required by the installed updates.
  • Moving the clustered roles back to the original nodes.
  • The Updating Run process also includes ensuring that quorum is maintained, checking for additional updates that can only be installed after the initial set of updates are installed, and saving a report of the actions taken.

To run this cmdlet with the PostUpdateScript or PreUpdateScript parameter, 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: Perform a scan and a full Updating Run on the specified cluster

$parameters = @{
    ClusterName = 'CONTOSO-FC1'
    CauPluginName = 'Microsoft.WindowsUpdatePlugin'
    MaxFailedNodes = '1'
    MaxRetriesPerNode = '3'
    RequireAllNodesOnline = $true
    Force = $true
}
Invoke-CauRun @parameters

This command performs a scan and a full Updating Run on the cluster named CONTOSO-FC1. This cmdlet uses the Microsoft.WindowsUpdatePlugin plug-in and requires that all cluster nodes be online before the running this cmdlet. In addition, this cmdlet allows no more than three retries per node before marking the node as failed, and allows no more than one node to fail before marking the entire Updating Run 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: Perform a scan and full Updating Run on the specified cluster using multiple plug-ins

$parameters = @{
    ClusterName = 'CONTOSO-FC1'
    CauPluginName = 'Microsoft.WindowsUpdatePlugin',
                    'Microsoft.HotfixPlugin'
    CauPluginArguments = @{ },
                         @{'HotfixRootFolderPath' = '\\CauHotfixSrv\shareName'}
    StopOnPluginFailure = $true
    EnableFirewallRules = $true
    SeparateReboots = $true
    Force = $true
}
Invoke-CauRun @parameters

This command performs a scan and a full Updating Run on the cluster named CONTOSO-FC1. This cmdlet uses the Microsoft.WindowsUpdatePlugin plug-in with the default configuration, and the Microsoft.HotfixPlugin plug-in using the hotfix root folder \\CauHotfixSrv\shareName and the default hotfix configuration file. If it isn't already enabled, the Remote Shutdown Windows Firewall rule group is enabled on each cluster node before the Updating Run. If a failure occurs during the installation of updates on a node by Microsoft.WindowsUpdatePlugin, updates aren't applied by Microsoft.HotfixPlugin plug-in. If the installation of updates by Microsoft.WindowsUpdatePlugin requires a node to restart, the node restarts before Microsoft.HotfixPlugin plug-in installs updates. 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: Recover from a previous Updating Run that failed on the specified cluster

Invoke-CauRun -ClusterName "CONTOSO-FC1" -ForceRecovery -Force

This command recovers from a previous Updating Run that failed and left the cluster in a Locked state for the cluster named CONTOSO-FC1. Because the command specifies the Force parameter, the recovery is performed without confirmation prompts.

Parameters

-AttemptSoftReboot

Indicates that command 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.

Parameter sets

DefaultParamSet
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments: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.

-EnableFirewallRules

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 automatically re-enables 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.

-RunPluginsSerially

Indicates that CAU will scan each cluster node for applicable updates and stage the updates for each plug-in in the plug-in order passed into the CauPluginName 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 for the CauPluginName parameter. If a single plug-in is specified, a warning appears.

-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.

-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. By default, a failure by one plug-in doesn't affect the application of updates on a node by other plug-ins.

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.

-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.
