For anyone that’s ever been through the process of provisioning a new datastore to multiple ESX hosts, you know it can take some time. Below are the steps I use
- Create Volume on NetApp
- Set Security Style to Unix
- Enable Storage Efficiency
- Set NFS Export permissions to allow Read/Write + Root Permissions to all applicable hosts
- Mount datastores on ESXi hosts
For a handful of hosts this is fine, but adding it to anything more than 4-5 hosts is reaaally painful in my experience. Below is a script you can use to take care of these steps in one swipe.
Prerequisites:
The script requires an array of the NFS clients (read ESXi hosts) you want to connect the datastore to.
Example 1 – assign the array to a variable, and manually add it to a parameter
|

|
$ESXHosts = @("10.1.1.100","10.1.1.101","10.1.1.102")
Add-VolumeAndAddToESXi.ps1 -VolName Volume100 -VolSize 1.5T -filerIP 10.1.1.10 -aggrName aggr0 -ExportedHosts $ESXHosts -vCenter vcenter-site1
|
Example 2 – Create an array, and pipe it to the script
|
1 |
@("10.1.1.100","10.1.1.101") | Add-VolumeAndAddToESXi.ps1 -VolName Volume101 -VolSize 200G -filerIP 10.1.1.10 -aggrName aggr1 -vCenter vcenter-site1

Enjoy! Let me know if you have any challenges or questions
