Dsc patch

Just like the SPProductUpdate resource, this one needs to be defined against every server in the farm. Patching Process In this article, I will demo the process of patching a SharePoint farm, however the process is the same if you wish to patch a SharePoint farm. Decide where you wish to save it. My recommendation is to put it on a Shared Network Location that all servers will be able to access.

However, you need to understand the implications of running the Update installer from a Network location using DSC, because your installation process may get stuck due to the User Account Control protection.

A much easier approach to transfer the needed files across the wire is to make use of the flexible Script DSC resource as shown in Figure 1. Figure 1. As you can see, the code is pretty straightforward and self-explanatory with the actual file copy carried out on Lines of Figure 1.

Nevertheless, you will need to setup the correct credentials and pass it to New-PSDrive in the event that the network file share is access protected. You can potentially skip the drive mapping and perform the copy operation directly with the UNC path of the network file share. This is provided that the latter permits anonymous access or the participating machines are part of an Active Directory domain network with appropriate access rights. Evidently, saving the user name and password as plain text is one major disadvantage here.

Further, you may also have to handle possible errors arising out of the unavailability of the arbitrarily selected network drive letter. To mitigate this, consider running Get-WmiObject to enumerate the drive types and associated letters that are already in use. At this juncture, all you need to do is to pack everything together within the declarative Configuration code block to arrive at Figure 2 Step 1 :.

Figure 2. To generate the Managed Object Format. Note that a Configuration block behaves exactly like a regular function. Assuming that the pre-requisites on the remote DSC target are fulfilled, namely PowerShell remoting and.

NET Framework 4. In a workgroup environment, be aware that using the -Credential parameter may be a necessity due to disparate security access profiles on the destination machines. Note: Prior to pushing out the configuration, you must remove the following entries from the. Now, with the successful transfer of the needed files to the target nodes through DscWMF5CopyFiles, the succeeding step is to prepare a separate DSC Configuration block to describe the actual desired settings of having and keeping WMF5 deployed as illustrated in Figure Figure 3.

In order for DSC to enforce the stated configuration, these scripts must be deployed together; Listing 1 shown in the next section below helps setup the dependencies. Re-running these steps are only required if new machines come into operations, servers get decommissioned or the path to the network file share is updated, for instance. Unless the destination nodes already have the xWindowsUpdate module installed, an error message will be generated when Start-DscConfiguration is executed:.

Therefore, keeping the xHotfix and Script code sections in distinct Configuration blocks is essential to ensure that dependencies can be maintained yet separately managed.

The upgrade sequence should be as follow: SharePoint Upgrade Sequence If we were to put this into words, we should be able to install the binaries on all servers in parallel.

Script We will start off by defining our Node structure in our configuration script. Like this: Like Loading Leave a Reply Cancel reply Your email address will not be published.
