Configuring and Using Backup Devices
Shared Devices in the SAN Environment
Chapter 250
✓ Use a lock name if the (physical) device will be used by another
host as well (shared device).
✓ Optionally, select direct access if you want to use this
functionality. If you use it, ensure that the libtab file is set up on
that host.
Configuration Methods
There are three configuration methods that depend on the platforms that
participate in the SAN configuration:
• You can use the Data Protector device autoconfiguration functionality
to configure devices and libraries in a SAN using the GUI. Device
autoconfiguration is available on the following operating systems:
Windows, HP-UX, Solaris, Linux, NetWare, and Tru64. Refer to
“Device Autoconfiguration” on page 50.
• If your environment consists only of Windows, HP-UX, and Solaris
systems, you can use the SANconf tool for autoconfiguring devices
and libraries using the command line. For more information, refer to
“Configuration Using the SANconf Tool” on page 51.
• If your environment contains systems that do not support device
autoconfiguration, use the manual configuration. For more
information, refer to “Manually Configuring the Library” on page 51.
Device Autoconfiguration
The Data Protector autoconfiguration functionality provides automated
device and library configuration on multiple hosts in a SAN
environment.
Limitations Autoconfiguration cannot be used to configure the following devices in a
SAN environment:
• mixed media libraries
• DAS or ACSLS libraries
•NDMP devices
Data Protector discovers the backup devices connected to your
environment. For library devices, Data Protector determines the number
of slots, the media type, and which drives belong to the library. Data
