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.

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

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

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.
