Using an array for server list

[Hemijimi]

I am trying to connect to my local ESXi hosts using an array that holds the host names. First I log into the vCenter and create the array, then try and connect using the array. I keep getting Invalid URI: The hostname could not be parsed.  What am I missing here? I do know that when I dump this to a txt file there seems to be white space at the end of each server name.

Connect-VIServer (MyvCenter) -User (My Username)-Password (My Password)

$esxiServers = get-vmhost | select-object Name

ForEach ($server in $esxiServers)

}

Connect-VIServer $server -User (My Username) -Password (My Password)

}

I am planning on using an encrypted password later. I am just trying to get this to work.

This worked for me. The first time I did have to say "Y" for multiple connections.

$servers = @("10.10.0.XXX","10.10.0.XXX")
foreach ($server in $servers) {
  write-host $server
  connect-viserver $server -username XXXXXXXX -password "XXXXXXXX"
}

What is it that you are ultimately trying to solve?

This is a larger (couple of hundred) locked down environment. I need to log into each host and grab a user list for a monthly audit review. I can create a txt file with the names and pull from there, but I wanted to make it so that if we made a change to the environment, like add a host or change the IP that I would still catch all the hosts.

Gotcha, when you export your list after running this command:

$esxiServers = get-vmhost | select-object Name

How are you saving that text file?

The reason I ask is that when you run that command you get an object back, not just a name.

How are you importing the .txt file after that?

In other words can I see more of your script?

Why not something like that. It's essentially what you wrote in your previous reply.

$Creds = Get-credentials

Get-content List-hosts.txt | foreach-object {
     write-host $_
     connect-viserver $_ credential $creds
     #Whatever command you need to run against each host

}

Just get the List-hosts.txt right.

That does work, but I am trying to make this so I don't have to manage a server list. I can dump a list to a to a file, but then I get spaces at the beginning/end of the file and after each server name and it will not connect. I get "Invalid URI: hostname could not be parsed."  If I go into the file and delete the added spaces at the end of each server name, then I am okay and it will work. I tried to automate that with some success. I can get rid of the first three lines that are header information and I can get rid of the lines at the end of the file, but I can't seem to get rid of the spaces after each server entry?

Attached is what I had initially thought might work, but this does add spaces at the end of each server entry when it is dumped to a file that I can't seem to get rid of?

[jpsider]

ah, So when creating your text file, why not extract the name of the Server?

$servers = get-vmhost

foreach ($server in $servers) {

  write-host $server

  write-host $server.Name

}

Note that $server is an object, when you write that to text file you will get an array style data.

$server.Name is just a string.

Actually I'm not sure why we are trying to use a txt file.

$Creds = Get-credentials  

$esxlist = (get-vmhost).name
$esxlist | foreach-object {  
     write-host $_  
     connect-viserver $_ credential $creds  
     #Whatever command you need to run against each host  
     disconnect-viserver -confirm:$false
} 

And if you want to export your host list

(get-vmhost).name >> esxlist.txt

[Hemijimi]

I agree vXav, but when I tried to run the code it lists the server name and then asks me for the server name for every entry in the array. See attached.

Thanks

The Credential parameter is missing a dash

$Creds = Get-credentials   

$esxlist = (get-vmhost).name 

$esxlist | foreach-object {   

     write-host $_   

     connect-viserver $_ -Credential $creds   

     #Whatever command you need to run against each host   

     disconnect-viserver -confirm:$false 

}

Thanks everyone for your help. With what LucD found and leaving the (s) off of the get-credentials, it works great.

Thanks again
