Overview:
In this two-day course, you will focus on learning the tools and skills necessary to troubleshoot VMware vSAN™ 6.6 implementations. You will gain practical experience with vSAN troubleshooting concepts through the completion of instructor-led activities and hands-on challenge lab exercises.

Product Alignment
•  VMware ESXi™ 6.5
•  vCenter Server 6.5
•  vSAN 6.6

Objectives:    By the end of the course, you should be able to meet the following objectives:
•  Describe the software components
•  Diagram how the components relate to each other
•  Describe vSAN object placement
•  Explain the differences between object states
•  Explain how storage policies affect object states
•  Predict how specific failures affect object states
 
Intended Audience:    Storage and virtual infrastructure administrators who want to use software-defined storage with vSAN.
 
Prerequisites:    This course requires completion of one of the following prerequisites:
•  Understanding of concepts presented in the VMware vSphere: Install, Configure, Manage [V6.5] course
•  Completion of the VMware vSAN: Deploy and Manage [V6.6] course or equivalent experience with
   VMware vSAN.
•  Experience working with linux command line interfaces.

The course presumes that a student can perform the following tasks with no assistance or guidance before enrolling:
•  Use VMware vSphere® Web Client for common operations
•  Create and manage VMware vCenter Server® objects, such as data centers, clusters, hosts, and virtual
   machines
•  Create and modify a standard switch
•  Modify a distributed switch
•  Create a VMware vSphere® VMFS datastore
•  Use a wizard or a template to create a virtual machine
•  Migrate a virtual machine with VMware vSphere® vMotion® and VMware vSphere® Storage vMotion®

If you cannot complete all of these tasks, VMware recommends that you complete the VMware vSphere: Install, Configure, Manage [V6.5] and VMware vSAN: Deploy and Manage [V6.6] courses before enrolling in VMware vSAN: Troubleshooting.
