# Pause file migration import session

Network-attached storage is a file-level storage architecture that makes stored data more accessible to networked devices.

## Prerequisites

See Roles and associated permissions to determine the user roles that can perform this task.

## About this task

See Understanding PowerMax File for storage systems for an overview of PowerMax File.

Click Pause to pause an import session that is in the Copy In Progress state during Initial Copy or Incremental Copy operations.

| NOTE: Background data transfer stops, but I/O to the source continues in the file import session during Incremental_Copy. A paused import session can be resumed or cancelled. When a user tries to pause an import session when an incremental copy is about to complete, the session can be transitioned automatically from the Paused state to the Ready_to_Commit state without the user having to resume the import session. The Ready_to_Commit state is equivalent to the Paused state in terms of the load on the source system.

## Steps

1. Select a storage system that supports PowerMax File migration.
2. Select Data Protection > File Migration.
3. Select File Imports.
4. Select a session that can be paused and click Pause.
5. Do one of the following:
   - Click Run In The Background to perform the operation in the background.
