You are an administrator for ABC.com. ABC.com, who has an existing SAN with DS-16B switches,
purchases an ED-24000B. ABC.com plans to employ a core-edge design. Currently, the SAN
supports HP-UX servers. However, after the fabric merge has been completed, the host can no
longer access the devices. How did this problem originate?

A.
The zones were created by port instead of WWN

B.
The core PID change affected the device IDs

C.
The HBA drivers were not compatible with the new switch firmware

D.
The host was online during the merge
