Step-by-Step – Installing System Center Operations Manager (SCOM) 2019 on Windows Server 2019 with SQL 2017

This post I will be installing System Center Operations Manager 2019 (SCOM) RTM, Build Number 10.19.10050.

Here is some of the background information. As this post will concentrate on the installation of SCOM 2019, I am going to omit the setup and configuration of the Domain Controller, Windows Server 2019 for the SCOM Management Server. Also to note, I am using a PaaS instance of SQL 2017 (hosted on Azure), likewise the entire environment lives on Azure in an IaaS and PaaS configuration.

Service Accounts and Local Administrator:

DomainAccount Description Local Admin on…
domainSCOM_AA SCOM Action Account SCOM
domainSCOM_DA SCOM Data Access/SDK Account SCOM
domainSCOM_SQL_READ SCOM SQL Reader n/a
domainSCOM_SQL_WRITE SCOM SQL Writer n/a
domainSCOM_Admins SCOM Administrators Group SCOM
domainSQL_SA SQL Service Account n/a

Now, if you’re lazy like me, or are tired of doing this setup for environments, I have scripted the automation of these accounts. You can find that link here, Microsoft TechNet Gallery.


Let’s Begin:

Since I am hosting SQL on a dedicated server, I will install SSRS (SCOM Reporting) on that server.

Well, that’s not new… Prerequisites. Since this is a clean, vanilla Windows 2019 server, we will need to install all the necessary Web Console components, along with Report Viewer Controls (probably SQL CLR Types too..).

  • For the Report Viewer Prerequisites, go HERE.
  • Here is the PowerShell command I ran to install the necessary IIS features/roles:
Import-Module ServerManager
Add-WindowsFeature Web-Server, Web-WebServer, Web-Common-Http, Web-Default-Doc, Web-Dir-Browsing, Web-Http-Errors, Web-Static-Content, Web-Health, Web-Http-Logging, Web-Log-Libraries, Web-Request-Monitor, Web-Performance, Web-Stat-Compression, Web-Security, Web-Filtering, Web-Windows-Auth, Web-App-Dev, Web-Net-Ext45, Web-Asp-Net45, Web-ISAPI-Ext, Web-ISAPI-Filter, Web-Mgmt-Tools, Web-Mgmt-Console, Web-Mgmt-Compat, Web-Metabase, NET-Framework-45-Features, NET-Framework-45-Core, NET-Framework-45-ASPNET, NET-WCF-Services45, NET-WCF-HTTP-Activation45, NET-WCF-TCP-PortSharing45, WAS, WAS-Process-Model, WAS-Config-APIs -restart

 

Once the server is back online, you will need to register ASP.Net.

You will need to apply the following using Command Prompt (as Administrator)). Yes, this is a screenshot from a previous post…Forgot to capture the screenshot when running it this time..

  1. cd %WINDIR%Microsoft.NETFramework64v4.0.30319
  2. aspnet_regiis.exe -r
  3. IISRESET
  4. Reboot your server…

Once the server is back online, let’s try that Prerequisites check again….

Great! Now all of Prerequisites have been met!

Provide a meaningful Management Group Name (there’s no going back after this…)

SQL Server will be where your SCOM SQL instance(s) were installed. Remember, to either disable the Windows Firewall, or open SQL TCP Ports 1433.

 

I recommend always keeping this off, and manually updating your SCOM infrastructure.

One quick review. Looks good. Hit Install, and get some fresh air!

A few minutes later….

Sweet! All good. I hope this helps. If you have any questions or issues, please drop me a line.

Happy 2019 SCOM’ing!

Data Deduplication in Windows Server 2019

When Windows Server 2016 was released, Data Deduplication was not available for ReFS file system, and only available for NTFS. With Windows Server 2019, data deduplication is now available for both NTFS and ReFS file systems.

Data Deduplication is a great technology that allows you to reduces your storage footprint by removing any duplicated data blocks and replacing it with metadata.

In the scenario below, I will show you how to enable Data Deduplication and tracking the ‘saving rate’ of the data deduplication.

Install-WindowsFeature FS-Data-Deduplication

This cmdlet will allow you to install the feature. In most scenarios, ie. Storage Spaces Direct, Hyper-V, this will make most sense. Also, this cmdlet would need to be executed on all nodes.

Get-Command *Dedup*

Now that we have data deduplication installed, we can now see all the of the cmdlets available.

Enable-DedupVolume -Volume "E:","F:" -UsageType HyperV

Finally, once we enable data deduplication on the volumes, we can now track the saving rate. Note, this can be done via PowerShell, or Windows Admin Center (WAC). Note, this can only be enabled on Cluster Shared Volumes (CSV).

Get-DedupVolume

I hope this helps, and now you can start minimizing the data deduplication within your environment.
