I’ve been stuck with this error recently on a Celerra manager device : DpRequest_Max_VS_SuspendedCheckpointsReached
This can sometimes happen when a filesystem is held during a replication task. To check what filesystems are currently being replcated run the following command;
nas_replicate -info -all
Either wait until the replication has completed – check status. Or temporary stop the replication task (stop it from the source side if possible).
