Can anyone assist with using the powershell command to add mutiple NFS shares accross multiple virtual centers reading from a CSV file.

Task
Create powershell command to look to a CSV file with a list of ESX hosts in different virtual center servers.

Add 4 NFS datastores.

Any assistance would be much appreciated!

Could you perhaps describe what is in the CSV file ? VC names and/or ESX hostnames ?
And where will get the account/password to logon to the VCs ? Or will this go via pass through with the account that runs the script ?

Adding a NFS datastore can be done with the New-Datastore cmdlet.
See NFS mount on multiple hosts

The CSV file will contain the host name and IP address in which we'll inject a different user account.

I'll assume that the CSV file contains the names of the VCs.
Then you can do something like this provided you have a header row in the CSV that says "VCname"
Import-Csv "C:\cvname.csv" | %{
	Connect-VIServer -Server $_.VCname
	Get-VmHost | New-Datastore -Nfs -Name NFSds -Path NFSds -RemoteHost <NFSserver> -RemotePath <NFSexport>
}

If there is no header row you can do
Import-Csv "C:\cvname.csv" -Header MyVC | %{
	Connect-VIServer -Server $_.MyVC
	Get-VmHost | New-Datastore -Nfs -Name NFSds -Path NFSds -RemoteHost <NFSserver> -RemotePath <NFSexport>
}


This assumes that the account with which you execute the script has rights on all the VCs.
The Connect-ViServer uses passthrough authentication.

I've been trying your script above and it keeps giving me the error at : Connect-VIServer -Server <<<< $_.MyVC


*
vSphere PowerCLI C:\Program Files\VMware\Infrastructure\VIToolkitForWindows> Connect-VIServer -Server $_.MyVC*
Connect-VIServer : Cannot validate argument on parameter 'Server'. The argument cannot be null or empty.

It looks like the import form the CSV file is not functioning.
Could you perhaps include a screenshot of the first few lines of this VC file?
You can scramble the text if you need to, I just want to see the layout.

Its exactly as below, I'm testing this against 2 hosts for the time being.

Thank you for assisting. Another question if you want to add multiple datastores?

servername.domain.com

servername.domain.com

There must be something wrong but I can't see what it is.
This is from a run of such a script on my test PC.
Note that I replaced the Connect-ViServer by a Write-Host to see the variable.

If you want to add multiple NFS datastores you have to repeat the line with the New-Datastore cmdlet.

Yea, I tried breaking this down and I get the CSV file imported succesfully.

Here is what I am doing to troubleshoot.

This part works fine, when I run this it returns the 2 host servers in the csv file
Import-Csv "C:\scripts\input.csv" -Header MyVC

This part errors out:
**%{*Connect-VIServer* -Server $_.MyVC Get-VmHost*

*

Is there really a Get-VmHost on the Connect-ViServer line ?
It should be
Import-Csv "C:\scripts\input.csv" -Header MyVC | %{
   Connect-VIServer -Server $_.MyVC
...
}

Perhaps you could PM me the script your are trying to use.
The forum SW sometimes scrambles code one inserts in a post.
