During migration for the indicated storage pool, the server cannot move the data from the storage pool, because a file is larger than what is allowed on the next storage pool.
The indicated migration process ends. The server waits for the retry period to expire and then tries the migration again. If other migration processes are executing for the named storage pool, these processes will continue migration.
Use the UPDATE STGPOOL command to change the next storage pool maximum file size or to change the next storage pool target.
