Windows 2008R2 Cluster hotfixes

What is CAU ? Cluster Update Automation with CAU

#CAU is a great new feature but how does it fit in your infrastructure ?

I have already a WSUS server and I use SCCM ,and I use WSUS for my DTAP environment, and now Do I need another WSUS server ? or can I reuse the old WSUS ?

WSUS 3.0SP2 (on W2K8R2): not yet compatible with Windows Server 2012

You can’t use SCCM to pull the Updates.

So basically install a downstream server for the CAU or primary wsus, if you have more WSUS servers you can sync the updates with powershell to hold the same info on all your other servers.

 

  • Single-click launch of cluster-wide updating operation
  • Or a single PS cmdlet
  • “Updating Run”image
  • Physical or VM clusters
  • CAU scans, downloads and installs applicable updates on each node
  • Restarts node as necessary
  • One node at a time
  • Repeats for all cluster nodes
  • Customize pre-update & post-update behavior with PS scripts

 

  • Updates (GDRs) from Windows Update or WSUS
  • Hotfixes (QFEs) from a local File Share
  • Simple customization that installs almost any software update off a local File Share

 

 

 

 

 

 

 

image

  • Adds CAU clustered role
  • Just like any other clustered workload
  • Resilience to planned and unplanned failures
  • Not mutually exclusive with on-demand updating
  • Analogy: Windows Update scan on your PC with AU auto-install
  • But possible conflicts with Updating Runs in progress
  • “Configured, but on hold” functionality
  • Compatible with VCO Prestaging

image

Powershell usage :

Sample: fill in the cluster name and the wsus share.

 

Invoke-CauScan -ClusterName CONTOSO-FC1 -CauPluginName Microsoft.WindowsUpdatePlugin, Microsoft.HotfixPlugin -CauPluginArguments @{}, @{ ‘HotfixRootFolderPath’ = ‘\\CauHotfixSrv\shareName'; ‘HotfixConfigFilePath’ = ‘\\CauHotfixSrv\shareName\DefaultHotfixConfig.xml’ } -RunPluginsSerially -Verbose
Invoke-CauRun -ClusterName CONTOSO-FC1 -CauPluginName Microsoft.WindowsUpdatePlugin, Microsoft.HotfixPlugin -CauPluginArguments @{ ‘IncludeRecommendedUpdates’ = ‘True’ }, @{ ‘HotfixRootFolderPath’ = ‘\\CauHotfixSrv\shareName';  ‘HotfixConfigFilePath’ = ‘\\CauHotfixSrv\shareName\DefaultHotfixConfig.xml’ } -MaxRetriesPerNode 2  -StopOnPluginFailure –Force

 

Options: RunPluginsSerially, StopOnPluginFailure, SeparateReboots

  • CAU supports only Windows Server 2012 clusters
  • Can be installed on Windows 8 Client RSAT package

Make CAU the only tool updating the cluster
Concurrent updates by other tools: e.g., WSUS, WUA, SCCM might cause downtime

For a WSUS-based deployment:

WSUS 4.0: needs a workaround with Beta builds (only) http://social.technet.microsoft.com/wiki/contents/articles/7891.how-wsus-and-cluster-aware-updating-are-affected-by-windows-server-8-beta-updates.aspx 
WSUS 3.0SP2 (on W2K8R2): not yet compatible with Windows Server 2012

Think about firewalls on nodes!
Windows Firewall Beta (or non-Windows firewall): create a firewall rule and enable it for domain-scope, wininit.exe program, dynamic RPC endpoints, TCP protocol
Windows Firewall RC: Enable the "Remote Shutdown" firewall rule group for the Domain profile, or pass the “-EnableFirewallRules” parameter to Invoke-CauRun, Add-CauClusterRole or Set-CauClusterRole cmdlets
Make sure GPOs agree
