VMware vSAN: Troubleshooting [V7]

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.
