# Function - Start-RSCMVSnapshot - Requesting an on demand snapshot of an RSC Managed Volume
################################################
Function Start-RSCMVSnapshot {
    
<#
.SYNOPSIS
Makes a regular Managed Volume writeable by initiating a begin snapshot request on ManagedVolumeID or ObjectID (same thing).
 
.DESCRIPTION
Only use this function for regular Managed Volumes, use Start-RSCMVSnapshot for SLA Managed Volumes and any other object type. It can also be piped a ManagedVolume object from Get-RSCManagedVolumes (see examples).
 
.LINK
GraphQL schema reference: https://rubrikinc.github.io/rubrik-api-documentation/schema/reference
 
.PARAMETER ObjectID
The RSC object ID of the managed volume which can be attained from Get-RSCManagedVolumes
 
.OUTPUTS
Returns an array with the status of the being snapshot request.
 
.EXAMPLE
Start-RSCMVSnapshot - ObjectID $ManagedVolumeID
Where the ObjectID is the Managed Volume ID you want to open/make writeable.
 
.EXAMPLE
Get-RSCManagedVolumes | Where {$_.ManagedVolume -eq "YOURMVNAME"} | Start-RSCMVSnapshot
Selecting a managed volume called YOURMVNAME and piping it to Start-RSCManagedVolumeSnapshot
