VMware vSphere: Troubleshooting [V7]

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

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

• Describe the architectural components of vSAN and their roles
• Explain how the components interact with each other
• Explain the differences between object and component states
• Describe how to use Skyline Health to investigate and help determine failure conditions
• Explain how to use the command-line tools to help determine failure conditions

You must complete one of the following prerequisites:

• Understanding of concepts presented in the VMware vSphere : Install, Configure, Managecourse
• Completion of the VMware vSAN: Deploy and Manage 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.
