Figure 2-9 Selecting Direct Access

Manually Configuring the libtab Files

The purpose of the libtab files is to map the library robotic control access so that it also works on the “direct access requesting system”, since here the local control path is likely to be different from the one used on the default library robotic control system.

You need to create a libtab file for every Windows and UNIX system client host that needs “direct access” to the library robotics, and is not identical to the system configured as the default library robotics control system.

On each system requesting direct access, a plain text file with the following format must be provided:

<FullyQualifiedHostname> <DeviceFile SCSIPath> <DeviceName>

•<FullyQualifiedHostname> is the name of the client host demanding direct access control for the library robotics. If the host is part of a cluster, the node name should be used.
