In this course, you focus on 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 handson 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 use software defined storage with vSAN

Course Introduction

• Introductions and course logistics
• Course objectives
   

vSAN Architecture

• Describe the vSAN architecture and components
• Describe the policy-driven, object-based vSAN storage environment
• Describe the vSAN software components: CLOM, DOM, LSOM, CMMDS, and RDT
• Explain the relationships between the vSAN software components
• Explain the relationship between objects and components
• Determine how specific storage policies affect components
• Describe component placement

Troubleshooting Methodology

• Use a structured approach to solve configuration and operational problems
• Apply troubleshooting methodology to logically diagnose faults and optimize troubleshooting efficiency

Troubleshooting Tools

• Discuss the improvements and added capabilities in Skyline Health for vSAN
• Use Skyline Health for vSAN to identify and correct issues in vSAN
• Discuss the ways to run various command line tools
• Discuss the ways to access VMware vSphere® ESXi™ Shell
• Use commands to view, configure, and manage your vSphere environment
• Discuss the esxcli vsan namespace commands
• Discuss when to use Ruby vSphere Console (RVC) commands
• Explain which log files are useful for vSAN troubleshooting
• Use log files to help troubleshoot vSAN problems

You must complete one of the following prerequisites:

• Understanding of concepts presented in the HM9P6S: VMware vSphere®: Install, Configure, Manage [V7.0] course
• Completion of the H0DR5S: VMware vSAN: Deploy and Manage [V6.7] course, or equivalent experience with vSAN
• Experience working with command-line interfaces

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

• 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.
