PowerShell – VMware PowerCLI get Datastore Information

Hello,

In this post I will show you how to get the datastore list in a vSphere infrastructure using PowerCLI. Now, first of all we have to establish connection to our vCenter/ESXi to get this information. We can do this using the “Connect-VIServer” command.

PS C:\Users\jocolon> Connect-VIServer -Server 192.168.5.2

Specify Credential
Please specify server credential
User: administrator@vsphere.local
Password for user administrator@vsphere.local: ********

Name                           Port  User
----                           ----  ----
192.168.5.2                    443   VSPHERE.LOCAL\Administrator

After the connection is established you can use the “Get-Datastore” command.

PS C:\Users\jocolon> Get-Datastore

This command shows the existing Datastore and the basic information about the used space. With this command we can also filter the search allowing to obtain additional Datastore information. if we add the Datastore name to the “Get-Datastore” command with the “-Name” option. For example if we use the command “Get-Datastore -Name <DatastoreName> | Format-List” the following result is shown.

PS C:\Users\jocolon> Get-Datastore -Name NVME-VFLASH-01 | Format-List

Like most Powershell commands, the PowerCLI commands allow the use of “Pipeline”. If we use the “Get-VMHost” command to get the ESXi servers together with the “Get-Datastore” command you can further filter the content of the Datastore connected to the server.

PS C:\Users\jocolon> Get-VMHost -Name esxsvr-00f.pharmax.local | Get-Datastore


Name                               FreeSpaceGB      CapacityGB

Finally, I would like to mention that there are endless possibilities in Powershell when it comes to interlinking cmdlets, allowing you to refine the search for data and even transform the information you want to display. I hope this information has been useful. Hasta luego!
