You can transfer the contents of an individual file, along with any FlashCopy® images that exist for that file, to another storage pool without disrupting service to the SAN File System clients. The file is defragmented and distributed across all available volumes in the target storage pool as its blocks are transferred.
If an application has a file open in read mode, the application can continue to access the file while the file is being moved. An application can also open a file in read mode while the file is being moved.
If an application has a file open in write or exclusive mode, any data I/O calls made by the application against the file will be delayed until the move is complete. Similarly, a request to open the file in write or exclusive mode while the file is being moved will be delayed.
