Tivoli Storage Manager for UNIX Backup-Archive Clients Installation and User's Guide

Enablelanfree

Authorized User

The enablelanfree option specifies whether to enable an available LAN-Free path to a storage area network (SAN) attached storage device. A LAN-Free path allows backup, restore, archive, and retrieve processing between the Tivoli Storage Manager client and the SAN-attached storage device.

To support LAN-Free data movement you must install and configure the Tivoli Storage Manager Managed System for SAN Storage Agent on the client workstation. For more information, refer to the following publications:

Notes:

  1. If you place the enablelanfree option in the client option file (dsm.opt), but zero (0) bytes were transferred through the SAN during an operation, ensure that you bind the data to a lanfree enabled management class.
  2. The enablelanfree option is not valid if HSM is installed. See Tivoli Space Manager for Unix Using the Hierarchical Storage Management Clients, GC32-0794 for more information.

To specify a communication protocol between the Tivoli Storage Manager client and Storage Agent, see Lanfreecommmethod for more information.

Note:
To restore backup sets in a SAN environment, see Restore Backupset for more information.
