During a power outage of a datacenter, a storage array did not shut down in a vendor's recommended fashion. When power is restored, the servers connected to the array indicate that the file systems ar

Enclosure addressing generally refers to the internal identification of components within the storage array or LUNs, and changes to it are not the most direct cause of file system corruption due to sudden power loss.

While an array controller failure could cause file system corruption, the scenario describes an improper shutdown due to a power outage, making data loss from the cache a more direct and probable cause than a physical controller failure.

Storage array controllers utilize a read/write cache to improve performance by buffering I/O operations. When a storage array experiences a sudden power loss without a graceful shutdown, any data residing in the volatile write cache that had not yet been committed to persistent storage (disk) is lost, leading to data inconsistency and file system corruption when power is restored.

Ungraceful shutdown of switches primarily affects network connectivity and not the integrity of data on the storage array's disks or file system consistency, as switches do not store persistent data relevant to file system states.
