VMware vSphere: Problēmu novēršana [V8]

This five-day training course provides you with the knowledge, skills, and abilities to achieve competence in troubleshooting the VMware vSphere® 8 environment. This course increases your skill level and competence in using the command-line interface, VMware vSphere® Client™, log files, and other tools to analyze and solve problems.

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

• Describe troubleshooting principles and procedures
• Use the vSphere Client, the command line, and log files to configure, diagnose, and correct problems in vSphere
• Explain the key vSphere log files from troubleshooting perspective
• Describe the benefits and capabilities of VMware Skyline
• Identify the networking issues by examining the reported symptoms, and troubleshoot the reported problems
• Identify the storage issues by examining the reported symptoms, and troubleshoot the reported problems
• Troubleshoot vSphere cluster failure scenarios and analyze possible causes
• Diagnose common VMware vSphere® High Availability (vSphere HA) problems and provide solutions
• Trouble virtual machine problems, including migration problems, snapshot problems, and connectivity problems
• Identify VMware ESXi™ host and VMware vCenter Server® problems, analyze failure scenarios, and find resolutions
• Troubleshoot performance problems with vSphere components

This course requires completion of one the following courses:

• VMware vSphere: Fast Track
• VMware vSphere: Install, Configure, Manage
• VMware vSphere: Operate, Scale and Secure

The course material presumes that you can perform the following tasks with no assistance or guidance before enrolling in this course:

• Install and configure ESXi
• Install vCenter Server
• Create vCenter Server objects, such as data centers and folders
• Create and modify a standard switch • Create and modify a distributed switch
• Connect an ESXi host to NAS, iSCSI, or Fibre Channel storage
• Create a VMware vSphere VMFS datastore
• Modify a virtual machine’s hardware
• Migrate a virtual machine with VMware vSphere® vMotion® and VMware vSphere® Storage vMotion®
• Configure and manage a VMware vSphere® Distributed Resource SchedulerTM cluster
• Configure and manage a VMware vSphere HA cluster
• Basic knowledge of command line tools like ESXCLI, DCLI, and PowerCLI

If you cannot complete these tasks, VMware recommends that you take the VMware vSphere: Install, Configure, Manage [V8] course instead.
