ABSTRACT:
A method of shutting down an information handling system is disclosed. Power is provided to a storage enclosure that includes a first storage device, a first operating condition monitor, and a first operating condition indicator having at least a first status and a second status. The status of the first operating condition indicator is updated based on the first operating condition monitor. One or more storage volumes are configured utilizing at least a portion of the storage enclosure. A first host detects the status of the first operating condition indicator. In response to detecting the first status of the first operating condition indicator, the first host determines whether the storage enclosure includes at least a portion of a critical storage volume and sends a shut down command from the first host to the storage enclosure. If the storage enclosure includes at least a portion of a critical storage volume, the first host is shut down.
