• <DeviceFile | SCSIPath> is the control path to the library robotic
driver on this client host.
• <DeviceName> is the name of the device definition used on this client
host.
You need one line per device for which you request direct access.
The libtab file is located on:
• <Data_Protector_home>\libtab on Windows systems
• /opt/omni/.libtab on HP-UX and Solaris systems
• /usr/omni/.libtab on other UNIX systems
Example files follow for all systems involved. Definitions are separated
by blank lines, which are ignored. Since the default library robotics are
defined on the host dupin.company.com, no libtab file is needed on this
system.
TIP It is possible to have only one libtab file that includes definitions for all
systems involved and is distributed to all such systems. In this case,
when a specific system needs “direct access” to the library robotic, the
definitions for other systems are ignored and only the definitions for the
system are used.
