Powershell multiple credential setup

问题

I just setup a powershell to collect disk space info among a group of servers. but I encounter an issue that while I try to authenticate from one server to another, it require different credential info.

E.g. SQLServer01

ID: domain1\sqladmin1

PW: 123456

SQLServer02

ID: domain2\sqladmin2

PW: 654321

right now i manage to setup first one with limited power-shell experience.

$comp= Get-Content "C:\disk_info\Computers.txt"
$diskvalue = @()
#$cre = get-Credential

$username = "domain1\sqladmin1"
$password = "123456"
$secureStringPwd = $password | ConvertTo-SecureString -AsPlainText -Force 
$creds = New-Object System.Management.Automation.PSCredential -ArgumentList $user, $secureStringPwd



foreach($pc in $comp)
{
    $diskvalue += Get-WmiObject -Class Win32_logicaldisk -ComputerName $pc -credential $creds -Filter DriveType=3 | 
    Select SystemName , DeviceID , @{Name=”size(GB)”;Expression={“{0:N1}” -f($_.size/1gb)}}, @{Name=”freespace(GB)”;Expression={“{0:N1}” -f($_.freespace/1gb)}}, @{Name=”UsedSpace(GB)”;Expression={“{0:N2}” -f(($_.size - $_.FreeSpace)/1gb)}}
    #$diskvalue -replace ":",""
    $diskvalue | Export-Csv C:\disk_info\DiskReport.csv -NoTypeInformation
    
}

Yet I am trying to input another credential for some servers only. domain2\ in this case.

Computer.txt as reference

sqlserver1.domain1.com 
sqlserver2.domain1.domain2.com 
sqlserver3.domain1.com

the one including "domain2" would be the need of multiple credential.

If you are using the full qualified domain names for the machine in Computers.txt, you could use a simple if statement to decide which domain credentials to use. You will just need to change the $domain2Match variable at the top to your 2nd domain in the below script ($domain2Match='.domain1.domain2.com').

$comp= Get-Content "C:\disk_info\Computers.txt"
$diskvalue = @()

# Put your FQDN without the server name here for the seconded domain
$domain2Match = '.domain1.domain2.com' 

# Credential 1
$username = "domain1\sqladmin1"
$password = "123456"
$secureStringPwd = $password | ConvertTo-SecureString -AsPlainText -Force 
$creds = New-Object System.Management.Automation.PSCredential -ArgumentList $user, $secureStringPwd

# Credential 2   
$username2 = "domain2\sqladmin2"
$password2 = "123456"
$secureStringPwd2 = $password2 | ConvertTo-SecureString -AsPlainText -Force 
$creds2 = New-Object System.Management.Automation.PSCredential -ArgumentList $user2, $secureStringPwd2


foreach($pc in $comp)
{
    $credsToUse = $null

    If($pc -imatch $domain2Match){
        # Matched use domain 2 Credential
        $credsToUse = $creds2 
    }Else {
        # No match use domain 1 Credential
        $credsToUse = $creds
    }

    $diskvalue += Get-WmiObject -Class Win32_logicaldisk -ComputerName $pc -credential $credsToUse -Filter DriveType=3 | 
    Select SystemName , DeviceID , @{Name=”size(GB)”;Expression={“{0:N1}” -f($_.size/1gb)}}, @{Name=”freespace(GB)”;Expression={“{0:N1}” -f($_.freespace/1gb)}}, @{Name=”UsedSpace(GB)”;Expression={“{0:N2}” -f(($_.size - $_.FreeSpace)/1gb)}}
    $diskvalue | Export-Csv C:\disk_info\DiskReport.csv -NoTypeInformation
}

You can create two Credenital Objects:

Cred 1

$username = "domain1\sqladmin1"
$password = "123456"
$secureStringPwd = $password | ConvertTo-SecureString -AsPlainText -Force 
$creds = New-Object System.Management.Automation.PSCredential -ArgumentList $user, $secureStringPwd

Cred 2

$username = "domain2\sqladmin2"
$password = "123456"
$secureStringPwd = $password | ConvertTo-SecureString -AsPlainText -Force 
$creds2 = New-Object System.Management.Automation.PSCredential -ArgumentList $user, $secureStringPwd

Then use an IF Statement along with splatting Params (will be easier and cleaner)

foreach($pc in $comp)
{

$Params = @{
Class = "Win32_logicaldisk"
ComputerName = $pc
Credential = $creds
Filter = 'DriveType=3' 
}

If ($pc -eq "SQLServer02")
{
$Params["Credential"] = $creds2
}
    $diskvalue += Get-WmiObject @Params | Select SystemName , DeviceID , @{Name=”size(GB)”;Expression={“{0:N1}” -f($_.size/1gb)}}, @{Name=”freespace(GB)”;Expression={“{0:N1}” -f($_.freespace/1gb)}}, @{Name=”UsedSpace(GB)”;Expression={“{0:N2}” -f(($_.size - $_.FreeSpace)/1gb)}}
    #$diskvalue -replace ":",""
    $diskvalue | Export-Csv C:\disk_info\DiskReport.csv -NoTypeInformation

  }
