Hello,

 

I am using SC_PowerShell_Toolkit_4.1.7.0.

After a SnapCreator Upgrade to version 4.3.0P3, the snapcreator powershell cannot connect to the scserver with the following error:

 

PS C:\Users\user> Connect-ScServer -Name <SnapCreatorServer> -Credential admin

Connect-ScServer : Could not establish secure channel for SSL/TLS with authority '<SnapCreatorServerIP>:8443'.

At line:1 char:1

+ Connect-ScServer -Name <SnapCreatorServer> -Credential admin

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo          : InvalidResult: (<SnapCreatorServer>:ScServer) [Connect-ScServer], SecurityNegotiationException

    + FullyQualifiedErrorId : HttpsConnectionFailed,NetApp.SnapCreatorPS.Server.Cmdlets.ConnectScServer

 

Hostname                                           Address                 ApiVersion

<SnapCreatorServer>      <SnapCreatorServerIP>           1.0

 

Any help is appreciated.

Hi,

 

Did the port number change during the upgrade? I had a look at the source code, it will default to 8443 if the port number is not provided.

Here is a sample of the source code, it fails with error "httpsConnectionFailed"before it fails it calls "ConnectHTTPS" which sets the port to 8443 (if it is not specified) (this.port.value : 8443)

 

 

		protected override void ProcessRecord()
		{
			if (string.IsNullOrEmpty(this.Name))
			{
				this.Name = "localhost";
			}
			ScServer server = new ScServer(this.Name);
			if (this.Credential == null)
			{
				base.ThrowTerminatingError(new ErrorRecord(new ArgumentNullException("Credentials not provided."), "CredentialsNotSpecified", ErrorCategory.InvalidArgument, null));
			}
			else
			{
				try
				{
					ConnectScServer.logger.Debug("Trying HTTPS");
					base.WriteVerbose("Trying HTTPS");
					this.ConnectHTTPS(server, this.Credential);
				}
				catch (Exception ex)
				{
					base.WriteError(new ErrorRecord(ex, "HttpsConnectionFailed", ErrorCategory.InvalidResult, server));
				}
			}
			if (server.EngineVersion == null)
			{
				ConnectScServer.logger.DebugFormat("Failed to connect to {0}", server.Hostname);
				base.WriteVerbose(string.Format("Failed to connect to {0}", server.Hostname));
				server = null;
			}
			else
			{
				ConnectScServer.logger.DebugFormat("Connected to {0} using {1}", server.Hostname, server.Protocol);
				base.WriteVerbose(string.Format("Connected to {0} using {1}", server.Hostname, server.Protocol));
			}
			if (!this.Transient)
			{
				this.SetSessionVariable(server);
			}
			base.WriteObject(server);
		}

		protected void ConnectHTTPS(ScServer server, PSCredential credentials)
		{
			server.Credentials = credentials.GetNetworkCredential();
			server.Port = (int)(this.Port.HasValue ? this.Port.Value : 8443);
			server.Protocol = ServerProtocol.HTTPS;
			ConnectScServer.logger.DebugFormat("Connecting to {0} via HTTPS", server.Hostname);
			this.GetEngineVersion(server);
			this.GetRbacVersion(server);
			this.GetRepositoryVersion(server);
			this.GetSchedulerVersion(server);
			this.GetStorageVersion(server);
		}

See the documentation here for checking\changing the port number

 

https://library.netapp.com/ecm/ecm_download_file/ECMLP2604630 (Page 15)

 

You could try specifying the port number when connecting. IE:

 

Param(
   [Parameter(Mandatory=$True, HelpMessage="The hostname or IP Address of the SnapCenter server")]
   [String]$HostName,
   [Parameter(Mandatory=$True, HelpMessage="The SnapCenter Port Number")]
   [Int]$PortNumber,
   [Parameter(Mandatory=$True, HelpMessage="The credentials to authenticate the to SnapCreator server")]   
   [System.Management.Automation.PSCredential]$Credentials
)
#'------------------------------------------------------------------------------
Import-Module SnapCreator -ErrorAction SilentlyContinue
Try{
   Connect-ScServer -Name $HostName -Port $PortNumber -Credential $credentials -ErrorAction Stop | Out-Null
   Write-Host "Connected to SnapCenter ""$HostName"" on port number ""$PortNumber"""
}Catch{
   Write-Warning -Message $("Failed connecting to SnapCenter ""$HostName"" on port number ""$PortNumber"". Error " + $_.Exception.Message)
   Break;
}
#'------------------------------------------------------------------------------

Then try connecting (assuming you save the above code as "C:\scripts\snapcreator\testconnect.ps1"). IE

 

 

PS C:\scripts\snapcreator>$credentials = Get-Credential -Credential admin
PS C:\scripts\snapcreator>.\testconnect.ps1 -HostName localhost -PortNumber 8443 -Credentials $credentials

I suspect it's more likely to be related to SSL\TLS security rather than an issue with the port number though.

Just trying to help eliminate the obvious first before troubleshooting further.

Hi Matt,

 

Thank you very much for your response,

 

The port number didnt change during the upgrade, the port is still the default port - 8443.

The "testconnect script" is getting the follow error; (you wrote 'snapcenter' instead of 'snapcreator')

WARNING: Failed connecting to SnapCenter "<SnapCreatorServer>" on port number "8443". Error Could not establish secure channel for SSL/TLS with authority '<SnapCreatorIP>:8443'.

 

I found something very strange,

I am trying to access the snap creator server from two different servers (a WFA server and the local SnapCreator server).

I get the "SSL" error from both of the servers (ApiVersion 1.0), but I found that in the snapcreator server, after a powershell connection to the netapp, the connection to the local snapcreator server works (ApiVersion 1.1). It doesnt work in the WFA server.

We haver snapcreator version 4.3.1 and having same error.

 

connect-scserver : Could not establish secure channel for SSL/TLS with authority 'Server:8443'.
At line:1 char:1

Is any way we can install API version 1.0

We used the workaround to connect the CDOT filer first but still we have issue.

Please help to fix the issue.

Hi,

 

Can you please try connecting using the following code. This will provide verbose output of the exception. Can you please post a screenshot of it?

I'd like to see the stack trace property of the error object to trace the source code.

   [Parameter(Mandatory=$True, HelpMessage="The hostname or IP Address of the SnapCenter server")]
   [String]$HostName,

   [Parameter(Mandatory=$True, HelpMessage="The credentials to authenticate the to SnapCreator server")]   
   [System.Management.Automation.PSCredential]$Credentials
)
#'------------------------------------------------------------------------------
