Reasons for SnapDrive to automatically stop Space Reclaimer

SnapDrive for Windows automatically stops Space Reclaimer in several instances.

• During any LUN management operation on a LUN running Space Reclaimer, including LUN disconnect and LUN delete operations
• During any Snapshot copy management operation except Snapshot copy rename and delete
• On all LUNs of the same storage system volume during Snapshot copy creation
• If the SnapDrive service is stopped
• During LUN restore operations for any volume mount points directly or indirectly mounted (cascading) from the disk being restored
• During Windows host cluster failover

  If a host cluster failover operation occurs on a Windows Server 2003 MSCS or Windows Server 2008 failover cluster while Space Reclaimer is running on a shared LUN, space reclamation will stop running on that LUN.

• During any MPIO path management operations, including adding or removing an initiator or active path selection
