Configuring and Using Backup Devices

 

Shared Devices in the SAN Environment

Prerequisite

Before configuring Data Protector devices in a SAN environment, the

 

Data Protector Media Agent must be installed on each host that needs to

 

communicate with the shared library. See the HP OpenView Storage

 

Data Protector Installation and Licensing Guide for more information on

 

installing a Media Agent.

Configuring the

To create the library itself, refer to “Configuring Library Devices” on

Library Robotics

page 29 or to the online Help topic “Configuring Devices in a SAN

 

Environment”.

 

For robotics control, you can use any host within the SAN; here the

 

system dupin.company.com is used. The library robotics will be

 

controlled by that host, unless the host is unavailable and direct access is

 

enabled as explained in detail in “Enabling Direct Access” on page 55.

Configuring the

If you want the robotic control to be managed by a cluster, you need to

Library Robotics

make sure that:

in a Cluster

• The robotics control exists on each cluster node.

 

 

• The virtual cluster name is used in the library robotics configuration.

 

• The common robotics and device filenames are installed either using

 

the mksf command or using the libtab file. For information on how

 

to configure the libtab file, refer to “Manually Configuring the libtab

 

Files” on page 56.

 

After you have configured the library robotics, create the drives.

 

Manually Configuring the Devices (Drives)

 

You need to configure each device (tape drive) on each host from which

 

you want to use the device.

 

Lock Names must be used to prevent the same device from being used by

 

several hosts at the same time. Optionally, the “direct access” mode can

 

be selected.

Configuring Drives As will be seen shortly, it helps to follow a drive naming convention similar to the following:

LibraryLogicalName_DriveIndex_Hostname, for example

SAN_LIB_2_computer_1.
