VMware vSAN: Troubleshooting [V7] (EDU-VSANT7)

In this two-day course, you focus on learning the tools and skills necessary to troubleshoot VMware vSAN™ 7 implementations. You gain practical experience with vSAN troubleshooting concepts through the completion of instructor-led activities and hands-on lab exercises.


Objectives

By the end of the course, you should be able to meet the following objectives:

  • Describe the software components of vSAN and their roles
  • Diagram how the components relate to each other
  • Use Skyline Health to investigate and help determine failure conditions
  • Use the command-line tools to help determine failure conditions

 

Intended Audience

Storage and virtual infrastructure administrators who want to be able to perform initial troubleshooting on their software-defined storage with vSAN

 

Prerequisites

You must complete one of the following prerequisites:

  • Understanding of concepts presented in the VMware vSphere®: Install, Configure, Manage [V7.0] course
  • Completion of the VMware vSAN: Deploy and Manage [V6.7] course or equivalent experience with vSAN
  • Experience working with command-line interfaces

The course presumes that a student can perform the following tasks with no assistance or guidance before enrolling:

  • Use VMware vSphere® 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 and VMware vSAN: Deploy and Manage courses before enrolling in VMware vSAN: Troubleshooting.
