Hitachi Ultrastar 15K450 (FC-AL) Hard Disk Drive Specification

through a 'discovery phase' with the enclosure as defined in the SFF-8067 standard.  The results of this discovery phase deter-
mine whether the enclosure:  1) does not support Enclosure Services, 2) supports only the 'short' Enclosure Services mode as 
defined by SFF-8045, or 3) supports the 'long' Enclosure Services mode as defined by SFF-8067.  After the discovery phase, 
the drive behaves in accordance with the Enclosure Services mode capabilities of the enclosure.  The drive does not attempt to 
remember the Enclosure Services capabilities of the enclosure, but rather, in accordance with the SFF-8067 standard, re-per-
forms the discovery phase for each SEND and RECIEVE DIAGNOSTIC command received.

 

Note: 

For a more detailed description of Enclosure Services, please refer to the following specifications:

SFF-8067 Specification 

21.15.1  Enclosure Initiated ESI

This drive supports Enclosure Initiated ESI as described in the SFF-8067 standard.

21.16  Multiple Initiator Environment

21.16.1  Initiator Sense Data

Separate sense data is reserved for each I-T-L. Each sense data is maintained independent of commands from other initiators.

21.16.2  Initiator Mode Select/Mode Sense Parameters

A single shared copy of the Mode Select/Mode Sense parameters is maintained by the drive. This includes both the current and 
saved parameters.

21.17  Reset

Reset actions will return the drive to a known, initialized state.

This device supports the Hard reset option as defined in the SCSI standards (see 7.1.9 Dev_Ctrl_Code_x on page 33) and the 
reset sources discussed below. 

Short

 

This mode is defined for use when an Enclosure simply supplies an 7-bit parame-
ter as defined by the SFF-8045 standard to the drive. 

When mounted in this type of Enclosure, an attempt to access any Enclosure Ser-
vice Diagnostic Page using the SEND DIAGNOSTIC command will terminate the 
command with CHECK CONDITION status. The sense data will have a Sense 
Key of Illegal Request and an Additional Sense Code of UNSUPPORTED 
ENCLOSURE FUNCTION. 

Requesting any Enclosure Service Diagnostic Page using the RECEIVE DIAG-
NOSTIC RESULTS command will return only Diagnostic Page 08h (Short Enclo-
sure Status).  

Long

This form is defined for use when the Enclosure and target are able to communi-
cate using the secondary interface as defined in the SFF-8067 standard. 

When mounted in this type of Enclosure, any attempt to access an Enclosure Ser-
vice Diagnostic Page using the SEND DIAGNOSTIC or RECEIVE DIAGNOS-
TIC RESULTS commands results in the Diagnostic Page being transferred to/from 
the enclosure. CHECK CONDITION status and sense data with an appropriate 
Sense Key and Additional Sense Code is generated if the transfer fails or cannot be 
performed.
