Troubleshooting Cisco Data Center Infrastructure (DCIT) — Question 86

A Cisco UCS B-Series Blade Server is configured to boot a VMware ESXi host from an EMC VNX storage array by using a Fibre Channel SAN. The boot order is confirmed to be configured as expected, but the server fails to boot from the SAN. Which action resolves the problem?

Answer options

• A. Set the boot LUN to the highest LUN ID in the storage array.
• B. Set the boot LUN to the lowest LUN ID in the storage array.
• C. Set the same WWNN pools for vHBA adapters.
• D. Set the same WWPN pools for vHBA adapters.

Correct answer: C

Explanation

The correct answer is C because having the same WWNN pools for vHBA adapters ensures that the adapters can communicate properly with the storage. The other options regarding LUN IDs do not directly address the communication issues between the adapters and the storage array, which is crucial for booting from the SAN.
