Mount multiple datastores in ESXi hosts using PowerCLI

To mount multiple datastores in ESXi hosts using PowerCLI, you can follow these steps and use the examples below. PowerCLI is a PowerShell module specifically designed to manage VMware environments, including vSphere and ESXi hosts.

  1. First, ensure you have PowerCLI installed. If it’s not already installed, you can install it from the PowerShell Gallery using the following command:
Install-Module -Name VMware.PowerCLI -Force -AllowClobber

2.Connect to your vCenter Server or ESXi host using the Connect-VIServer cmdlet. Replace “vCenterServer” or “ESXiHost” with your actual server’s IP or FQDN.

Connect-VIServer -Server vCenterServer -User administrator -Password YourPassword
  1. Once connected, you can mount the datastores using the New-Datastore cmdlet. The New-Datastore cmdlet allows you to mount multiple datastores on an ESXi host.

Here’s an example of how to mount two datastores on a single ESXi host:

# Variables - Replace these with your actual datastore and ESXi host information
$Datastore1Name = "Datastore1"
$Datastore1Path = "[SAN] Datastore1/Datastore1.vmdk"
$Datastore2Name = "Datastore2"
$Datastore2Path = "[SAN] Datastore2/Datastore2.vmdk"
$ESXiHost = "ESXiHost"

# Mount Datastore 1
$Datastore1 = New-Datastore -Name $Datastore1Name -Path $Datastore1Path -VMHost $ESXiHost -NFS -NfsHost 192.168.1.100

# Mount Datastore 2
$Datastore2 = New-Datastore -Name $Datastore2Name -Path $Datastore2Path -VMHost $ESXiHost -NFS -NfsHost 192.168.1.101

In the example above:

  • Replace $Datastore1Name and $Datastore2Name with the names you want to give to your datastores.
  • Replace $Datastore1Path and $Datastore2Path with the paths to your datastores on the storage (e.g., NFS or VMFS path).
  • Replace $ESXiHost with the name or IP address of your ESXi host.

The New-Datastore cmdlet will mount the specified datastores on the ESXi host you provided. Make sure the necessary networking and storage configurations are in place before executing the script.

Once the datastores are mounted, you can verify them using the Get-Datastore cmdlet:

# Get all datastores on the specified ESXi host
Get-Datastore -VMHost $ESXiHost

Remember to always test new scripts in a controlled environment before running them in production to avoid unintended consequences.
