Acknowledgment
T10/BSR INCITS 502 Revision 19
The editor would like to express the acknowledgment that this draft standard is what it is due to the efforts of
the previous editor, Mr. Ralph O. Weber of ENDL Texas. As previous editor of this draft standard, Mr. Weber
delivered a nearly finished document. Indeed, Mr. Weber was also the editor of the previous versions of
SPC-4, SPC-3, SPC-2, and SPC.
It is this editor’s opinion that the data storage industry, and the standards community both owe Mr. Weber a
debt of thanks for his significant contributions to this and other standards. Further, this editor would like to
extend his sincere thanks for Mr. Weber’s patient tutelage in the arcana of standards development.

T10/BSR INCITS 502 Revision 19
2018 Feb 14
III. Revision History
III.1 Revision 00 (13 December 2014)
Revision 0 of SPC-5 is substantially equal to revision 37a of SPC-4. The only differences arise from changes
made in SPC-4 by the ANSI Editor during the INCITS Public Review process. Wherever possible, the
changes are highlighted with change bars. In summary, the ANSI editor corrected a handful of bogus cross
references, added several commas, and fixed a few spelling errors.
The change bar exception occurs in table 6 where the three bullets that form the ellipsis were changed from a
non-standard font to Arial font. Since no changes were made that would be visible to the unaided eye, no
change bar highlights the difference.
The list of obsolete features was truncated in clause 1. It will contain entries soon enough. The Foreword was
modified to not list committee members.
For the record, the only changes in SPC-4 text that forms the basis of SFSC were in the CbCS description,
which is not contained in SFSC per the changes made by T10 approved document 14-167r0.
III.2 Revision 00a (22 December 2014)
This revision contains a bevy of editorial changes that were not appropriate for the ANSI Editor to make.
b)
a) Cleaned up the wording in the definition of the RECEIVE CREDENTIAL command's Logical unit
designation descriptor format.
In several cases where the If: list, then: list construct is used, the semi-colon before the then: was
corrected to be a comma.
c) A table with the FrameMaker “float” attribute was corrected to start “Anywhere”.
d) Missing description text for the PAGE CODE field as added in the Supported Log Pages log page
subclause.
e) The column headings were modified to eliminate line wraps in the PCR bit, the SP bit, and the PC field
meanings when parameter list length is zero table.
f) Twice in the description of what the REQUEST SENSE command returns, the unnecessary 'that' was
removed from “if the logical unit that reports a …”.
g) The employer for the T10 chair was updated.
h)
In the master numeric list of operation codes, the START STOP UNIT command was removed as an
optional OSD-2 command. While OSD may have allowed use of the START STOP UNIT command,
OSD-2 does not.
The references clause and Bibliography were updated to conform to the latest T10 Style Guide, a
needed enhancement for sending SPC-4 to ISO/IEC for international processing.
i)
j) Changed references to cancelled UAS-2 project back to UAS.
k) The additional sense codes lists were updated to:
A) align with ZBC by adding the following:
INSUFFICIENT ZONE RESOURCES;
a)
b) ZONE IS OFFLINE; and
c) RESET WRITE POINTER NOT ALLOWED;
and
B) capture all the approved additional sense code definitions approved since May, 2014.
l) Version descriptors and the SCSI Roadmap were updated to reflect the status in December, 2014.
Some of these changes were not highlighted with change bars.
m) The vendor id list was updated to the latest one maintained by the T10 website.
