Introduction

During the course of your VSAN deployment or during production following deployment, you may encounter a problem that requires deep, low-level troubleshooting or complex issue analysis. If this should occur, you may need to open a case with VMware Support or your third-party support provider.

As we have seen, VSAN is tightly integrated with vSphere once it is deployed, so in some ways, preparing for a support engagement with VSAN is quite similar to the regular vSphere support process. VSAN does, however, involve many elements and configuration items that are not found in non-VSAN infrastructures. To set ourselves up for success during support engagements, there are steps we can take to ensure that all the necessary data is provided up-front to avoid delays to acquire more information after the incident is raised. Properly defining the problem and providing adequate diagnostic data can help make recovering from problems and returning to production faster and easier.
