Enablelanfree

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 backup-archive client and the SAN-attached storage device.

To support LAN-free data movement you must install and configure the IBM Spectrum Protect for SAN storage agent on the client workstation.

Notes:

If you place the enablelanfree option in the client options file (dsm.opt), but zero (0) bytes were transferred through the SAN during an operation, ensure that you bind the data to a LAN-free enabled management class.
To restore backup sets in a SAN environment, see for more information.
When a LAN-free path is enabled, the SAN Storage Agent settings override the client tcpserveraddress, tcpport, and ssl options. This override action occurs to ensure that both the client and the Storage Agent use the same server communication options.
Client encryption with the include.encrypt option is no longer supported for LAN-free backup and archive operations to the IBM Spectrum Protect server V8.1.1 and later levels, or V7.1.8 and later V7 levels. LAN-free restore and retrieve operations of encrypted backup versions and archive copies continue to be supported. If you need to encrypt data by using the include.encrypt option, in which data is encrypted before it is sent to the server, use LAN-based backup or archive operations.
