Sending failure information from a solid state drive (SSD) to a host device
View Patent ↗A system, method, and computer program product are provided for sending failure information from a solid state drive (SSD) to a host device. In operation, an error is detected during an operation associated with a solid state drive. Additionally, a command is received for failure information from a host device. Further, the failure information is sent from the solid state drive to the host device, the failure information including failure information associated with the solid state drive.
1. A method, comprising:
detecting an error during an operation associated with a solid state drive (SSD);
receiving from a host device a command to return failure information; and
sending the failure information from the SSD to the host device in response to the receiving, the failure information comprising information relevant to the SSD being comprised of flash memory as a storage media.
2. The method of claim 1 , wherein the information relevant to the SSD being comprised of flash memory as a storage media comprises a specific storage media location of the flash memory where the error occurred.
3. The method of claim 2 , wherein the information relevant to the SSD being comprised of flash memory as a storage media further comprises information indicating whether the specific storage media location of the flash memory is associated with corrupt data.
4. The method of claim 1 , wherein the information relevant to the SSD being comprised of flash memory as a storage media comprises information indicating that the SSD was unable to free up a storage media location of the flash memory in which to write data for the operation.
5. The method of claim 1 , further comprising:
wherein subsequent to a determination that the error is associated with a reoccurring event, the information relevant to the SSD being comprised of flash memory as a storage media comprises a persistent failure indication; and
wherein prior to the determination, the information relevant to the SSD being comprised of flash memory as a storage media comprises a transient failure indication.
6. The method of claim 1 , wherein the information relevant to the SSD being comprised of flash memory as a storage media comprises information indicating where the SSD is on a life expectancy curve.
7. The method of claim 1 , wherein the failure information is a Serial ATA (SATA) read log 10 page comprising a vendor specific field and the information relevant to the SSD being comprised of flash memory as a storage media is the vendor specific field.
8. The method of claim 1 , wherein the information relevant to the SSD being comprised of flash memory as a storage media is one or more of a plurality of fields associated with a Serial ATA (SATA) read log 10 page.
9. The method of claim 1 , wherein the failure information is capable of being utilized to recover failure information associated with an NCQ command issued to the SSD.
10. The method of claim 1 , wherein the command includes a command that is capable of being used to fetch SSD information to recover from an NCQ command and failure information associated with the NCQ command.
11. The method of claim 1 , wherein the failure information is accessible utilizing a command other than a Serial ATA (SATA) Read Log EXT command or a Serial ATA (SATA) Read Log DMA command.
12. The method of claim 1 , wherein the failure information is accessible utilizing a Serial ATA (SATA) Read Log EXT command.
13. The method of claim 1 , wherein the failure information is accessible utilizing a Serial ATA (SATA) Read Log DMA command.
14. The method of claim 1 , wherein the information relevant to the SSD being comprised of flash memory as a storage media further comprises a format associated with a Serial ATA (SATA) log page 10.
15. The method of claim 1 , wherein the operation includes sending an NCQ command.
16. The method of claim 1 , wherein the operation includes sending a SATA command.
17. A computer program product embodied on a non-transitory computer readable medium, comprising:
computer code for detecting an error during an operation associated with a solid state drive (SSD);
computer code for receiving from a host device a command to return failure information; and
computer code for sending the failure information from the SSD to the host device, the failure information comprising information relevant to the SSD being comprised of flash memory as a storage media.
18. An apparatus, comprising:
a solid state drive (SSD) configured to:
detect an error during an operation associated with the SSD;
receive from a host device a command to return failure information; and
send the failure information from the SSD to the host device, the failure information comprising information relevant to the SSD being comprised of flash memory as a storage media.
