Summary
The documentation is heavily focused on Windows environments, specifically Windows Server Failover Clustering (WSFC). All operational examples, scripts, and tooling references are for Windows and PowerShell. There is no mention of Linux equivalents, nor are any Linux-based high-availability clustering solutions (such as Pacemaker/Corosync) or Linux command-line examples provided. The documentation assumes a Windows-only context throughout, from infrastructure setup to SAP installation and failover testing.
Recommendations
- Add a parallel section or separate article for Linux-based SAP ASCS/SCS HA with Azure shared disk, using Pacemaker/Corosync or other supported Linux clustering solutions.
- Provide Linux command-line examples (e.g., using Azure CLI, shell scripts) for disk creation, attachment, and formatting.
- Include instructions for configuring load balancers and health probes in Linux environments, referencing relevant Linux tools and configuration files.
- Describe how to set up DNS entries and cluster resources using Linux-native tools (e.g., `crm`, `pcs`, or systemd-resolved).
- Reference SAP installation procedures for Linux, including any OS-specific SAP profile or kernel parameter adjustments.
- Clearly state at the beginning of the article that it is Windows-specific, and provide a link to Linux documentation if available.
