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>

You can execute the VMFS resignaturing operation using the esxcfg-volume command. Listed here are all the options for this command:

You can list all the VMFS volumes that have been detected as snapshots or replicas using the esxcfg-volume command with the -l option. You can find one VMFS UUID, 54e2a884-74597529-015b-2c44fd8309d4, that has been created as a snapshot, as shown in the following screenshot:

Note

The preceding command is used to list the VMFS volumes that have been detected as snapshots or replicas in vSphere 4.x.

You need to list the VMFS volume snapshots using the esxcli storage vmfs snapshot list command, if the vSphere host is version 5 or above. The following result is for your reference:

If you plan to mount the VMFS volume snapshot, you can execute the operation using the esxcli storage vmfs snapshot mount command. Listed here are all the options for esxcli storage vmfs snapshot mount:

According to the preceding result...
