Why each option
To diagnose a degraded RAID 5 array, the technician should first review the RAID log to identify the specific cause of the degraded status.
Reviewing the RAID log is the crucial first step in diagnosing a degraded RAID array as it provides detailed historical information about events, errors, and the status of individual drives. This log helps pinpoint which specific drive has failed or what other issue led to the degraded state, guiding subsequent troubleshooting actions.
Reseating the RAID controller is a physical troubleshooting step that should only be performed after logs indicate a potential connection issue.
Reconnecting RAID cables is a physical troubleshooting step that should only be performed after logs indicate a potential connection issue.
Upgrading the RAID firmware is a maintenance task, not a primary diagnostic step for an already degraded array.
