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>

Analyzing PSA and multipathing using esxcli


In Chapter 5, Optimizing Storage, we covered some examples of managing vSphere storage using esxcli. Now you will learn some more commands used to manage vSphere storage in this chapter. First, let's read about a useful command called esxcfg-mpath. It is used to list all paths or paths with the HBA adapter and device mappings, and so on. In the following screenshot, we can see all the options for the esxcfg-mpath command:

This table lists the description of options of the esxcfg-mpath command:

Option

-l

List all the paths on the system, with detailed information about them.

-L

List all the paths with abbreviated information.

-m

List all the paths with adapter and device mappings.

-b

List all the devices, with their corresponding paths.

-s

Set the state for a specific LUN path. This requires the path UID or path runtime name in path.

-G

List all the multipathing plugins loaded into the system.
