Defining Drivemapping

Use this command to define a drivemapping for sending data directly to a device on a storage area network (SAN).  To define the drivemapping, first complete the following fields and then click Finish, or click Cancel to end the task.

Storage Agent Name

Select the name of the storage agent as specified in the DEFINE SERVER command. This parameter is required.

Library Name

Select the name of the library to which the drive is defined. This parameter is required for all drives, including stand-alone drives. 

Drive Name

Select the name assigned to the drive whose device name you wish to alias.  This parameter is required.

Device

Enter the device name used to access the drive from the storage agent. This parameter is required.

Device On-Line

Select the drive availability for the storage agent. This parameter is optional.

Yes Specifies that the drive is available for use.
No Specifies that the drive is not available for use. 

Directory

This parameter is only valid for Drives in File Libraries, for example, disk storage shared by a storage agent and server. It specifies the directory location of the files used by the storage agent which is sharing access. The directory location may vary among systems accessing the same data on the SAN. Tivoli Storage Manager does not take action to create shares, permissions, or to get the target file system mounted. These actions must be taken prior to starting the storage agent.

The default is the directory of the server at the time the command is issued, unless the DSMSERV_DIR environment variable has been set. For additional information about the DSMSERV_DIR variable, refer to the Quick Start manual.

By specifying a directory name, you identify the location where the server reads and writes the files that represent storage volumes for the device class associated with the FILE device class. It is recommended that a naming convention be used that allows you to associate the directory with a particular physical drive; this will help ensure that your configuration is valid for sharing directories between the server and storage agent.
