What this book covers
Chapter 1, vCenter Upgrades and Migrations, provides an understanding of the best practices and the typical steps when upgrading to vCenter 6.0. The chapter also addresses instances where an installation has started with SQL Express as the vCenter database, but there was a desire or need to upgrade to the full version on SQL Server. It shows the SQL Server upgrade steps. When installing the VCSA, there is usually a DCHP service for that installation, but if not, this chapter will show you how to deploy VCSA without a DCHP server. Further, it will also cover the migration process from the Windows-based (C#) vCenter to the VMware vCenter server appliance.
Chapter 2, Working with the vCenter Database, helps diagnose and fix connection problems between the vCenter server and the database that is used to keep the vSphere inventory. vCenter uses the database to keep track of all vSphere information and cannot function without it. The chapter will also help the administrator understand how to recover from an improper shutdown as it pertains to the database.
Chapter 3, Setting Access and Permissions, shows you how to reset or unlock the single sign-on password, which is essential to vCenter. This chapter will also cover the permission difference VCOps and vCenter and assist in the translation of permissions from vSphere to vCOps and how they work together. It will cover the relationship between Active Directory (AD) and vCenter and how to solve possible problems when connecting AD and vCenter.
Chapter 4, Monitoring and Performance Considerations, covers topics with operations manager and how it is used to monitor components of vSphere. It will show how Operations Manager can identify I/O-intensive virtual machines in your environment. The chapter will also explore how vCenter uses Java and how to configure it to obtain the best performance. The chapter will help the administrator correct the problem caused by changes made to vCenter that prevents performance information from being displayed.
Chapter 5, Working with Storage, deals with a select number of storage issues. It will show the administrator how to remove a LUN from multiple ESXi hosts. It will also help you troubleshoot and resolve the problem of snapshot files that are locked and cannot be deleted. It will also cover using vCenter operations for troubleshooting storage devices.
Chapter 6, Solving Some Not-so-common vCenter Issues, helps you fix the problem when no objects show up in your vCenter inventory. The chapter will also help resolve the error message VPXD must be stopped to perform this operation in the VCSA. Finally, the chapter will also show the administrator how to remove plugins that are no longer wanted in the vCenter environment.
Chapter 7, Backup and Recovery, helps the administrator plan for the worst. Protecting the vCenter environment is essential to prevent partial data loss, or a complete loss of the vSphere environment. This chapter will show you how to prepare and recover from this administrator's nightmare. It will show not only what to backup, but also the method you can use to perform the backup. Your backups are useless unless you can recover the information from them. It will also provide the guidance needed to perform a successful recovery.
Chapter 8, Additional Support Methods and Tools, shows the administrator how to use the vCenter support assistant to obtain quicker responses when problems are reported. It also provides information and links to some of the free tools used to support the vSphere environment.
Chapter 9, Troubleshooting Methods, puts together a standard workflow to be used to help solve problems that might arise in your environment. Part of finding a resolution is having an approach that helps you discover and isolate the cause of the problem. Using the workflows will also help collect the information needed for you to resolve the problem yourself or submit the problem to a support service.
