IBM Tivoli Storage Manager, Version 7.1

Defining paths

Before a device can be used, a path must be defined between the device and the server or the device and the data mover responsible for outboard data movement.

About this task

The DEFINE PATH command must be used to define the following path relationships:

Between a server and a drive or a library.
Between a storage agent and a drive.
Between a data mover and a drive or a library.

When issuing the DEFINE PATH command, you must provide some or all of the following information:

Source name: The name of the server, storage agent, or data mover that is the source for the path.
Destination name: The assigned name of the device that is the destination for the path.
Source type: The type of source for the path. (A storage agent is considered a type of server for this purpose.)
Destination type: The type of device that is the destination for the path.
Library name: The name of the library that a drive is defined to if the drive is the destination of the path.
Device: The special file name of the device. This parameter is used when defining a path between a server, a storage agent, or a NAS data mover and a library or drive.
Automatic detection of serial number and element address: For devices on a SAN, you can specify whether the server should correct the serial number or element address of a drive or library, if it was incorrectly specified on the definition of the drive or library. The server uses the device name to locate the device and compares the serial number (and the element address for a drive) that it detects with that specified in the definition of the device. The default is to not allow the correction.

See the following examples:

If you have a SCSI type library named AUTODLTLIB that has a device name of /dev/lb3, define the path to the server named ASTRO1 by doing the following:

define path astro1 autodltlib srctype=server desttype=library 
device=/dev/lb3

If you have a drive, DRIVE01, that resides in library AUTODLTLIB, and has a device name of /dev/mt4, define it to server ASTRO1 by doing the following:

define path astro1 drive01 srctype=server desttype=drive library=autodltlib 
 device=/dev/mt4

If you have a SCSI type library named AUTODLTLIB that has a device name of /dev/rmt/tsmlb3, define the path to the server named ASTRO1 by doing the following:

define path astro1 autodltlib srctype=server desttype=library 
device=/dev/rmt/tsmlb3

If you have a drive, DRIVE01, that resides in library AUTODLTLIB, and has a device name of /dev/rmt/tsmmt4, define it to server ASTRO1 by doing the following:

define path astro1 drive01 srctype=server desttype=drive library=autodltlib 
 device=/dev/rmt/tsmmt4

If you have a SCSI type library named AUTODLTLIB that has a device name of /dev/tsmscsi/lb3, define the path to the server named ASTRO1 by doing the following:

define path astro1 autodltlib srctype=server desttype=library 
device=/dev/tsmscsi/lb3

If you have a drive, DRIVE01, that resides in library AUTODLTLIB, and has a device name of /dev/tsmscsi/mt4, define it to server ASTRO1 by doing the following:

define path astro1 drive01 srctype=server desttype=drive library=autodltlib 
 device=/dev/tsmscsi/mt4

For example, if you have a SCSI type library named AUTODLTLIB that has a device name of /dev/rmt/3lb, define the path to the server named ASTRO1 by doing the following:

define path astro1 autodltlib srctype=server desttype=library 
device=/dev/rmt/3lb

If you have a drive, DRIVE01, that resides in library AUTODLTLIB, and has a device name of /dev/rmt/4mt, define it to server ASTRO1 by doing the following:

define path astro1 drive01 srctype=server desttype=drive library=autodltlib 
 device=/dev/rmt/4mt
