Step 4. List and create LUN ID mappings
Table 46 shows that a different LUN from a storage array is presented as the same LUN ID (2) on
two different servers (HR-Dept, iPortal).

Step 5. List and create Fibre Channel zoning
Assume that Table 47, show a redundant configuration, meaning there are:
• Two Fibre Channel switches
• Multiple servers, each with two adapter ports
• One storage array with two controllers
• Four ports per controller
