Lanfreecommmethod

If you are using LAN failover, you must have lanfreecommmethod in the dsm.sys file within a server stanza.

If you are using LAN failover, you must have lanfreecommmethod TCPip in the client options file (dsm.opt).

For AIX®, HP-UX, Linux and Solaris, use the lanfreeshmport option to specify the shared memory port number where the Storage Agent is listening.

For Windows, use the lanfreeshmport option to uniquely identify the storage agent to which the client is trying to connect.

Supported Clients

This option is only valid for AIX, HP-UX, Linux, and Solaris clients.

This option is valid for all Windows clients.

Options File

Place this option in the dsm.sys file within a server stanza.

Place this option in the client options file (dsm.opt).

Parameters

commmethod

Specifies the supported protocol for your Tivoli Storage Manager client:

TCPip

The Transmission Control Protocol/Internet Protocol (TCP/IP) communication method.

Use the lanfreetcpport option to specify the TCP/IP port number where the Storage Agent is listening. The TCP/IP communication method is the default for non-root users on all supported platforms.

TCPip

The Transmission Control Protocol/Internet Protocol (TCP/IP) communication method.

Use the lanfreetcpport option to specify the TCP/IP port number where the Storage Agent is listening.

V6Tcpip

Indicates that either TCP/IP v4 or v6 should be used, depending on the system configuration and results of a domain name service lookup. The only time this is not true is when dsmc schedule is used and schedmode is prompt. A valid DNS environment must be available.

NAMedpipes

The interprocess communication method that permits message data streams to pass between a client and a server. This is the default. Do not specify the lanfreetcpport option if you want to use the NAMedpipes communication method for LAN-free communication.

SHAREdmem

Use the shared memory communication method when the client and Storage Agent are running on the same system. Shared memory provides better performance than the TCP/IP protocol.

SHAREdmem

Use the shared memory communication method when the client and Storage Agent are running on the same system. Shared memory provides better performance than the TCP/IP protocol. This is the default communication method for AIX, HP-UX, Linux, and Solaris root users. When specifying this communication method on AIX, the backup-archive client user can be logged in as root or non-root, as long as the Storage Agent is running as root. If the Storage Agent is not running as root, the user ID running the Backup-Archive Client must match the user ID running the Storage Agent.
