OBTAINING DIAGNOSTIC INFORMATION THROUGH HOST INTERFACES

摘要

Systems, methods, and apparatuses are provided to obtain diagnostic information from a storage device. A read command may be transmitted to a storage device, where the read command conforms to a block level storage protocol and is directed to an unused logical unit of storage memory included in the storage device, to an invalid logical block address, and/or to a mode page. The unused logical unit may be a predetermined logical unit of the storage memory that is not allocated by a file system. Diagnostic data may be received from the storage device in response to the read command. The diagnostic data may be information related to operation of the storage device and/or a component of the storage device.

1. A storage device comprising:
a storage memory; a diagnostic data collector configured to collect diagnostic data related to operation of the storage device; and a diagnostic logical unit manager configured to transmit the diagnostic data, which is collected by the diagnostic data collector, to a host device in response to a read command, wherein the read command is directed to a logical unit of the storage memory that is unallocated, to an invalid logical block address, and/or to a mode page, wherein the read command conforms to a block level storage protocol, and the block level storage protocol is a protocol in which storage devices are read from and written to in units of logical data blocks.
