If you're changing the server power state, make sure you pass in the exact string value since the values are case sensitive. Supported parameters: - idrac_ip: Pass in the iDRAC IP - idrac_username: Pass in the iDRAC user name - idrac_password: Pass in the iDRAC user name password - x_auth_token: Pass in iDRAC X-Auth token session to execute cmdlet instead of username / password (recommended) - power_request_value: Pass in the value you want to change the server power state to - get_power_state_only: Get current server power state and supported values to change server power state .EXAMPLE Set-PowerControlREDFISH -idrac_ip 192.168.0.120 -idrac_username root -idrac_ password calvin -get_power_state_only This example will get current server power state and supported values to change server power state. .EXAMPLE Set-PowerControlREDFISH -idrac_ip 192.168.0.120 -get_power_state_only This example will first prompt to enter iDRAC username and password using Get-Credentials, then get current server power state. .EXAMPLE Set-PowerControlREDFISH -idrac_ip 192.168.0.120 get_power_state_only -x_auth_token 7bd9bb9a8727ec366a9cef5bc83b2708 This example will get current server power state using iDRAC X-auth token session. .EXAMPLE Set-PowerControlREDFISH -idrac_ip 192.168.0.120 -idrac_username root -idrac_password calvin -power_request_value On This example will execute action to power ON the server. #> function Set-PowerControlREDFISH { param( [Parameter(Mandatory=$True)] [string]$idrac_ip, [Parameter(Mandatory=$False)] [string]$idrac_username, [Parameter(Mandatory=$False)] [string]$idrac_password, [Parameter(Mandatory=$False)] [string]$x_auth_token, [Parameter(Mandatory=$False)] [string]$power_request_value, [Parameter(Mandatory=$False)] [switch]$get_power_state_only ) # Function to ignore SSL certs function Ignore-SSLCertificates { $Provider = New-Object Microsoft.CSharp.CSharpCodeProvider $Compiler = $Provider.CreateCompiler() $Params = New-Object System.CodeDom.Compiler.CompilerParameters $Params.GenerateExecutable = $false $Params.GenerateInMemory = $true $Params.IncludeDebugInformation = $false $Params.ReferencedAssemblies.Add("System.DLL") > $null $TASource=@' namespace Local.ToolkitExtensions.Net.CertificatePolicy { public class TrustAll : System.Net.ICertificatePolicy { public bool CheckValidationResult(System.Net.ServicePoint sp,System.Security.Cryptography.X509Certificates.X509Certificate cert, System.Net.WebRequest req, int problem) { return true;
