function Set-DMLunGroup {
    <#
    .SYNOPSIS
        Modifies an OceanStor LUN group.
    .DESCRIPTION
        Modifies a LUN group by name. NewName and Description are first-class properties; ApiProperties
        passes additional Huawei LUN-group API fields through unchanged.
 
        Accepts multiple LUN groups from the pipeline by property name. Each LUN group is modified
        independently: a failure (e.g. an invalid/ambiguous name, a name collision, or a REST error)
        is reported as a non-terminating error and does not stop the rest from being processed.
        NewName is not meaningful for a batch of more than one LUN group.
 
    .PARAMETER WebSession
        Optional session returned by Connect-deviceManager. The module's cached $script:CurrentOceanstorSession session is used by default.
 
    .PARAMETER LunGroupName
        Existing LUN group name to modify.
 
    .PARAMETER NewName
        New name for the LUN group.
 
    .PARAMETER Description
        New description. An empty string clears the description.
 
    .PARAMETER ApiProperties
        Additional Huawei API modification fields to send verbatim.
 
    .PARAMETER VstoreId
        Optional vStore ID used to scope the operation.
 
    .INPUTS
        System.Management.Automation.PSCustomObject
 
        You can pipe an OceanStor session object to WebSession.
 
    .OUTPUTS
        System.Management.Automation.PSCustomObject
 
        Returns the OceanStor API error object indicating success or failure of the modification.
