1 - Connecting to the Server

When using a volume on the server, connection or disconnection work is required.
In the File Storage Details page, add the connection server and then connect to the server to perform the connection work (Mount, Network Drive Connection). After use, perform the disconnection work (Umount, Network Drive Disconnection) and then remove the connection server.

Connecting to the Server (Mount, Network Drive Connection)

To use the volume added to the connection server, you must connect to the server and perform the connection work (Mount, Network Drive Connection). Follow the procedure below.

Linux Operating System (NFS)

1. Click the All Services > Storage > File Storage menu. Move to the Service Home page of File Storage.

2. On the Service Home page, click the File Storage menu. Move to the File Storage List page.

3. On the File Storage List page, click the resource to be used by the connection server. Move to the File Storage Details page.
