VMware vSphere: Troubleshooting [V7]

•  System administrators
•  System integrators

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

• Introduce troubleshooting principles and procedures
• Practice Linux commands that aid in the troubleshooting process
• Use command-line interfaces, log files, and the vSphere Client to diagnose and resolve problems in the vSphere environment
• Explain the purpose of key vSphere log files
• Identify networking problems based on reported symptoms, validate and troubleshoot the reported problem, identify the root cause and implement the appropriate resolution
• Analyze storage failure scenarios using a logical troubleshooting methodology, identify the root cause, and apply the appropriate resolution to resolve the problem
• Troubleshoot vSphere cluster failure scenarios and analyze possible causes
• Diagnose common VMware vSphere® High Availability problems and provide solutions
• Identify and validate VMware ESXi™ host and VMware vCenter Server® problems, analyze failure scenarios, and select the correct resolution
• Troubleshoot virtual machine problems, including migration problems, snapshot problems, and connection problems
• Troubleshoot performance problems with vSphere components

This course requires completion of one of the following prerequisites:

• VMware vSphere: Fast Track [V6.x] or [V7]
• VMware vSphere: Install, Configure, Manage [V6.x] or [V7]
• VMware vSphere: Optimize and Scale [V6.x] or [V7]
• Equivalent knowledge and administration experience with ESXi and vCenter Server

Experience in working with a command-line interface is highly recommended.
