SAN Environment Configuration

Because the library is attached to several systems that can access its
drives directly, you need to configure as many drives on each host as you
want to use from that host. In this case, all four physical drives are to be
used from each host.

From a Data Protector perspective, the goal is as follows.

• On each host that is to share the library robotics, create a library

robotics definition for each host. If there is only one host that is
controlling the robotics, the library definition is created only for the
default robotics control host.

• On each host that is to participate in sharing the same (tape) drives

in the library:

✓ Create a device definition for each device to be used.
