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.
