SNIA Certified Storage Networking Expert (CSNE) — Question 3

Your customer has a Fibre Channel SAN environment and has properly zoned servers for storage with front end controller ports. When an administrator goes to initialize a provisioned volume, it is not seen on the server.
What would cause this problem?

Answer options

• A. an unplugged cable
• B. a multi-path I/O failure
• C. a corrupted volume
• D. improper LUN masking

Correct answer: B

Explanation

The correct answer is B, as a multi-path I/O failure can prevent the server from accessing the storage volume, thus not displaying it. An unplugged cable (A) could also cause connectivity issues, but the scenario suggests that zoning is correct. A corrupted volume (C) would likely still show up but fail on initialization, and improper LUN masking (D) would restrict visibility, but the context indicates I/O paths are the primary concern.
