IBM SC32-0129-00 manual Multi-session No-Query Restore for LAN-free Path

3.A request is made to the storage device to mount the appropriate media.

4.The library manager notifies the storage agent of the location where the mounted media resides. In the external library case, the storage agent is informed of the device location by the external library manager.

5.The client, by means of the storage agent, writes the backup data directly to the device over the SAN.

6.The storage agent sends metadata information to the Tivoli Storage Manager server, and the server stores the information in its database.

Multi-session No-Query Restore for LAN-free Path

When performing a no-query restore, the Tivoli Storage Manager server builds a list of files to restore and sends data to the client while continuing to build the list. This allows the restore to be restarted if interrupted.

Multiple sessions are used for the no-query restore when data for the restore resides on devices with a LAN-free path and devices with a LAN-only path. Some sessions restore data from the server with a LAN-only path. The other sessions use the storage agent to restore data over the LAN-free path. This works only with clients at Version 4.2 or above.

Note that the number of sessions used for the restore is dependent on the value of the client RESOURCEUTILIZATION option and the number of server volumes that contain the client data to be restored.

The following outlines a typical multi-session no-query restore for a LAN-free path:

1.The client requests a file space to be restored. This request is forwarded to the server.

2.The server determines the files to restore and the volume on which those files reside. The server generates a list, sorted by the volume name.

3.The client is informed of the progress and the number of volumes. The client can start more sessions to restore the information.

4.The location of the volume, and whether or not the storage agent can access the volume, will determine how the data is handled. When the volume can be mounted on a shared device that the storage agent can access, the data is read from the volume by the storage agent and sent to the client. When the volume cannot be mounted on a shared device that the storage agent can access, the data is read from the volume by the server and sent directly to the client. The client then begins additional sessions: some to the storage agent for the volumes that are LAN-free enabled and some sessions to the server for those volumes that are not LAN-free enabled.

5.The process repeats until all files in the list are restored.
