Abstract
A system and method for lun migration between data containers, such as aggregates of a storage system is provided. A new destination lun is created on a destination aggregate. A background copy process is then started that copies all data from a source lun on a source aggregate to the destination lun. The storage system continues to process client-originated data access requests directed to the source lun while the background copying continues. Once all the data of the source lun has been copied to the destination lun, processing of data access requests to the lun(s) is quiesced by the storage system. Lun maps of the storage system are then updated and processing of the client-originated data access requests is resumed with those requests now being directed to the destination lun.
