Introduction 1.1 Project/Component Working Name: Acoustic Management support under SATA module 1.2 Name of Document Author/Supplier: Author: Lida Horn 1.3 Date of This Document: July 12, 2007 4. Technical Description 4.1 Problem The support of Acoustic Management support has been requested by the HDD (Sun hard drive qualification group) in order to qualify more SATA hard drives for Sunfire x4500. The HDD group is doing a study in conjunction with Seagate and Hitachi manufacturing to see if using quiet mode helps in reducing the errors generated by the hard drives when there are a lot of vibration issues. The T13 ATA/ATAPI-8 specification indicates that device performance and acoustic emanation may increase with increasing acoustic management levels. The Automatic Management feature set is an ATA optional feature set that allows the host to select an acoustic management level. This feature has been requested for drivers under the SATA module kernel/misc/sata. The T10 SCSI/ATA Translation (SAT) Date:2006/09/13; Rev 09 and SCSI/ATA Translastion-2 (SAT-2) Date:2007/07/11, Rev 01a do not provide a translation mechanism from SCSI to SATA. There was a need to come up with a scheme to perform acoustic management in a SCSI environment. (Note: The SCSI specification does not provide a mechanism for drives to set the acoustic level.) 4.2 Proposal SCSI mode sense will be used to acquire the acoustic management level and vendor recommended value and whether or not the feature is enabled. The mode select will be used to turn on and off the acoustic management features and to set the acoustic management level. There are 3 bytes defined for the Sun vendor specific mode page (0x30). The first byte is 0 for acoustic management if disabled (mode sense) or to disable (mode select). The value is 1 for enabled (mode sense) or to enable (mode select). The second byte is the current value of the acoustic management level (mode sense) or the value which is desired (mode select in the case of the first byte being 1, meaningless if the first byte is 0). The third byte is the vendor recommended value (mode sense). This byte is meaningless for mode select. 4.3 Interface The uscsi ioctl can be utilized to acquire or set the acoustic management features. (The format command provides a mechanism to display the content of the page. The interface between the SATA module and the hba drivers is consolidation private. 4.4 References o T13 AT Attachment-8 ATA/ATAPI Command Set Revision 4a May 21,2007 T13/1699-D o T10 SCSI/ATA Translation (SAT) Revision 09 September 13, 2006 o T10 SCSI/ATA Translation-2 (SAT-2) Revision 01a July 11, 2007 o T10 SCSI-3 Block Commands(SBC) Revision 08c November 13, 1997 o T10 SCSI Block Commands -2 (SBC-2) Revision 16 November 13, 2004 4.5 man page: No man page needed.
