Hi Raj,
I would not recommend using "invoke-ncssh". Consider using "invoke-ncsystemapi" instead which enables you to run an SSH command via HTTPS. Here is an example to connect to a cluster, run the system health subsystem show command and format the CLI results using comma delimited output:
Source Code:
Param(
[Parameter(Mandatory = $True, HelpMessage = "The cluster to show the 'system health subsystem show' command for")]
[String]$Cluster,
[Parameter(Mandatory = $True, HelpMessage = "The credentials to connect to the cluster")]
[System.Management.Automation.PSCredential]$Credentials
)
#'------------------------------------------------------------------------------
Function Format-SystemHealthSubsystem{
Param(
[Parameter(Mandatory = $True, HelpMessage = "The CLI output of the 'system health subsystem show' command")]
[Array]$CLIOutput
)
[Array]$results = @();
[String]$header = $($CLIOutput[0] -Replace '(^\s+|\s+$)', '' -Replace '\s+', ' ').ToString().Trim()
[Array]$results += $header -replace ' ', ','
For($i=2; ($i -le $CLIOutput.Count - 2); $i++){
[String]$result = $($CLIOutput[$i] -Replace '(^\s+|\s+$)', '' -Replace '\s+', ' ').ToString().Trim()
[Array]$results += $result -replace ' ', ','
}
Return $results;
}#End Function
#'------------------------------------------------------------------------------
#'Import the NetApp DataONTAP PowerShell toolkit.
#'------------------------------------------------------------------------------
[String]$moduleName = "DataONTAP"
Try{
Import-Module -Name $moduleName -ErrorAction Stop
Write-Host "Imported module ""$moduleName"""
}Catch{
Write-Warning -Message $("Failed importing module ""$moduleName"". Error " + $_.Exception.Message)
Break;
}
#'------------------------------------------------------------------------------
#'Connect to the cluster.
#'------------------------------------------------------------------------------
Try{
Connect-NcController -Name $cluster -HTTPS -Credential $Credentials -ErrorAction Stop | Out-Null
Write-Host $("Connected to cluster ""$Cluster"" as user " + $Credentials.GetNetworkCredential().UserName)
}Catch{
Write-Warning -Message $("Failed connecting to cluster ""$Cluster"". Error " + $_.Exception.Message)
Break;
}
#'------------------------------------------------------------------------------
#'Invoke the SSH command via HTTPS.
#'------------------------------------------------------------------------------
Try{
$command = @("system", "health", "subsystem", "show")
$api = $("<system-cli><args><arg>" + ($command -join "</arg><arg>") + "</arg></args></system-cli>")
$output = Invoke-NcSystemApi -Request $api -ErrorAction Stop
Write-Host $("Executed Command`: " + $([String]::Join(" ", $command)))
}Catch{
Write-Warning -Message $("Failed Executing Command`: $command. Error " + $_.Exception.Message)
Break;
}
If($output.results."cli-result-value" -eq 1){
[Array]$CLIOutput = $output.results."cli-output".Trim().Split("`n")
Format-SystemHealthSubsystem -CLIOutput $CLIOutput
}Else{
Write-Warning -Message $("Failed Executing Command`: " + $([String]::Join(" ", $command)))
Break;
}
#'------------------------------------------------------------------------------
Output:
PS C:\Scripts\PowerShell\Projects\SystemHealthSubSystemShow> $credentials = Get-Credential -Credential admin
PS C:\Scripts\PowerShell\Projects\SystemHealthSubSystemShow> .\SystemHealthSubSystemShow.ps1 -Cluster cluster1.testlab.local -Credentials $credentials
Imported module "DataONTAP"
Connected to cluster "cluster1.testlab.local" as user admin
Executed Command: system health subsystem show
Subsystem,Health
Switch-Health,ok
CIFS-NDO,ok
MetroCluster,ok
MetroCluster_Node,ok
FHM-Switch,ok
FHM-Bridge,ok
Hope that helps
