Mastering VMware vSphere Storage

By: Victor Wu, Eagle Huang

Overview of this book

<p>vSphere Storage is one of the three main infrastructure components of a vSphere deployment (Compute, Storage, and Network).</p> <p>Mastering VMware vSphere Storage begins with an insightful introduction to virtualization and creating your own virtual machines. We then talk about VMware vCenter Server and virtual machine management, as well as managing vSphere 5 using vSphere Management Assistant (vMA) and esxcli and vmware-cmd commands. We then swiftly move on to a very interesting topic, reviewing the vSphere performance and troubleshooting methodology. We then configure VM storage profiles, Storage DRS, and Storage I/O control. More significantly, we will troubleshoot and analyze storage using the VMware CLI and learn how to configure iSCSI storage.</p> <p>By the end of the book, you will be able to identify useful information to make virtual machine and virtual data center design decisions.</p>

Chapter 7. Analyzing vSphere Storage by CLI

In the previous chapter, you learned about storage components, such as the LUN name, identifier name, and runtime name; how to set up LUN masking in a vSphere host using esxcli commands; and setting up the vSphere Syslog Collector to collect the ESXi host's log. During configuration and installation, the vSphere administrator may collect some information (such as the WWN of the host bus adapter of the vSphere host) and verify the path policy of the vSphere host. Executing the command is more convenient than using the vSphere client.

In this chapter, we will cover these topics:

  • Analyzing PSA and multipathing by esxcli

  • Applying VMFS volume copies resignaturing

  • Troubleshooting VMware snapshots and VMFS resignaturing

  • VMFS data store volume unmounting

  • Identifying and tagging SSD devices
