.SYNOPSIS
    Reactivates an OceanStor snapshot consistency group.
 
.DESCRIPTION
    Reactivates an existing snapshot consistency group by resolving its name to the group ID before calling the OceanStor API.
    Reactivation refreshes the consistency point. The group vStore ID is passed through when available. The cmdlet supports -WhatIf and -Confirm.
 
.PARAMETER WebSession
    Optional session object returned by Connect-deviceManager. When omitted, the module's cached $script:CurrentOceanstorSession session is used.
 
.PARAMETER Name
    Name of the snapshot consistency group to reactivate.
 
.INPUTS
    System.Management.Automation.PSCustomObject
 
.OUTPUTS
    System.Management.Automation.PSCustomObject
    Returns the OceanStor API error object.
 
.EXAMPLE
    PS> Restart-DMSnapshotConsistencyGroup -Name 'scg-production' -WhatIf
 
    Shows what would happen if scg-production were reactivated.
