Passing command line arguments in PowerCli script

[Vanit]

Hi All,

I know that we can connect to any vmware server using Connect-VIServer cmdlet in our script by providing all credentials of server but I want to pass it through command line.

I am able to connect the server by hardcoded login information in the script using Connect-VIServer cmdlet but I want that server will collect all necessary login information from command line and assign it which are required for Connect-VIServer to connect the server.

For example, I am having test1.ps1 script and when I will execute the script with arguments,it should be taken by Connect-VIServer cmdlet to connect the server written in the script.

[vSphere PowerCLI] C:\Scripts> C:\Scripts\test1.ps1 Server_IP_Address User_Name Password

I appreciate the effort in advance :smileyhappy:

Thanks!

If you begin your PowerCLI script with:

param($Server,$User,$Password)
Connect-VIserver -Server $Server -User $User -Password $Password

you can call it as in your example. The param() line defines the parameters you can specify on the command line. You can also call your script with:

C:\Scripts\test1.ps1 -Server Server_IP_Address -User User_Name -Password Password

Thanks a lot for reply.

Now I have written the script and want to add the following in the script attached in the post–

• There should check for the command-line arguments and those are required should be checked that there is something.
• I also want to check and error handling if the first argument is not a valid address or hostname for a VMware server or if the login information is incorrect? If any of them are not correct, error should be written in log file and exit from the script.
• Check for vSphere PCLI is installed or not. If not, it should throw an error.
• Proper Error handling at appropriate places in script and exit status.

Please help me to implement the above. I appreciate the effort in advance.

Thanks!!

Several of these requirements are built into PowerShell.

For example

#requires -pssnapin VMware.VimAutomation.Core -version 5.0

 param(
[parameter(Mandatory = $true)]
[ValidateScript({
    "vc1","vc2" -contains $_.Split('.')[0]
})]
$server,
[parameter(Mandatory = $true)]
$User,
[parameter(Mandatory = $true)]
$Password)

Write-Host $Server, $User $Password 

• will make sure PowerCLI 5.0 is present
• will make sure there are values for Server, User and Password
• will make sure that the Servername contains either vc1 or vc2 for the hostname

There are several more parameter validation possibilities. See about_Functions_Advanced_Parameters
