Episode 118 — HBA and Controller Issues — Advanced Storage Adapter Failures

This episode focuses on diagnosing problems with host bus adapters (HBAs) and storage controllers, which are critical for connecting servers to storage devices. We discuss symptoms of adapter failure, such as intermittent connectivity, degraded performance, and device detection errors. Configuration mismatches, outdated firmware, and driver incompatibility are also highlighted as common causes.

We then explore real-world and exam scenarios, such as troubleshooting an HBA that drops connections to a Fibre Channel SAN or resolving a RAID controller firmware bug that causes array instability. Troubleshooting steps include updating drivers and firmware, reseating adapters, and replacing defective hardware. Understanding these issues equips candidates to restore stable storage connectivity quickly and effectively.
