function New-SCBConnection{
    <#
.SYNOPSIS
    Set up the connection between the SCB server and the IBM Storage PowerShell Client.
    Before using the PowerShell client, create a PowerShell interface user.
.DESCRIPTION
    Setup the connection to the SCB server, and a SCBConnection object will be returned if successful.
.PARAMETER ConnectionUri
    Alias L; The connection URI for SCB server in the https://SCBIPAddress:ServicePort(8440) format.
.PARAMETER Credential
    User credentials for connection to the SCB server.
.PARAMETER Username
    Alias U; User name and password for the SCB server connection must be specified.
    The user can be created on the Spectrum Control BaseGUI, when creating a PowerShell interface.
    Other non-PowerShell-interface users will be limited to access some SCB functions
.PARAMETER Password
    Alias P; The corresponding password.
 
.EXAMPLE
$client=New-SCBConnection -ConnectionUri https://9.115.250.45:8440
If Credential or Username/Password is not provided, a Credential dialog will pop up to input username/password information.
 
.EXAMPLE
$client=New-SCBConnection -ConnectionUri https://9.115.250.45:8440 -UserName powershell -Password passw0rd!
Or in short form using parameter aliases: $client=New-SCBConnection -L https://9.115.250.45:8440 -U powershell -P passw0rd!

function Remove-SCBVolume{
<#
.SYNOPSIS
    Removes the volume or multiple volumes; For the operation on single volume, it will return $True if the volume is successfully removed, otherwize it will return $False; For multiple volumes, a dictionary, with VolumeID as the key and operation result as the value, will be returned.
 
.PARAMETER VolumeID
    Alias ID; The volume ID or Unique Identifier(id).
.PARAMETER Force
    Indicates whether to remove the mapping relationships if exist.
.PARAMETER SCBConnection
    The client handle for SCB server. It can be created via New-SCBConnection. If the SCBConnection is not specified, a most recently used SCBConnection will be utilized by default. The connection can be found via the global variable $Global:DefaultConnection. If multiple SCB servers are connected, you must explicitly specify the SCBConnection parameter.
 
.EXAMPLE
Remove-SCBVolume -VolumeID 6005076801A707416800000000000B85 -SCBConnection $client
Removes a volume via its ID.
