Configuring and Using Backup Devices

Shared Devices in the SAN Environment

<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.

 

 

Example libtab Example of the libtab file on host zala.company.com (Windows):

file on zala

zala.company.com scsi:2:0:2:0 SAN_LIB_1_zala zala.company.com scsi:2:0:2:0 SAN_LIB_2_zala zala.company.com scsi:2:0:2:0 SAN_LIB_3_zala zala.company.com scsi:2:0:2:0 SAN_LIB_4_zala

Example libtab Example of the libtab file on host oda.company.com (HP-UX):

file on oda

oda.company.com /dev/spt/lib SAN_LIB_1_computer_2 oda.company.com /dev/spt/lib SAN_LIB_2_computer_2 oda.company.com /dev/spt/lib SAN_LIB_3_computer_2 oda.company.com /dev/spt/lib SAN_LIB_4_computer_2
