What is the most likely reason that the customer is forced to use jbconfig rather than the Device Administration window?

A customer is adding a new jukebox to an EMC NetWorker environment. The jukebox is connected and powered on. The customer powers on the NetWorker server and verifies the new library is visible to the OS. The customer brings up the Device Administration window and verifies the existing jukebox is functioning properly.

However when the customer attempts to configure the new library using the Device Administration window function "Configure All Libraries", it fails to configure and instructs the customer that they must use jbconfig to manually configure this library.

What is the most likely reason that the customer is forced to use jbconfig rather than the Device Administration window?
A . NetWorker is unable to read the device serial numbers.
B . The jukebox WWPNs are not zoned into the SAN properly.
C . The /etc/rc3.d/S95networker failed to execute completely.
D . The tape devices in the jukebox are identified as AIT-2 format.

Answer: A
