What is indicated by the "Inoperable" RAID status?

The "Inoperable" RAID status indicates that there is a critical issue preventing the RAID array from functioning correctly. Specifically, this status suggests that one or more drives are missing from the array, which typically leads to a breach of the RAID's redundancy. In a RAID setup, missing drives can compromise data integrity and availability, which is why the system is labeled as "inoperable."

The absence of drives means that the RAID cannot perform its intended function of providing data redundancy and/or performance improvements, depending on the RAID level implemented. Correctly identifying this status is crucial for troubleshooting and restoring RAID functionality, as it helps administrators take appropriate actions, such as replacing the missing drives or investigating the cause of their absence.
