A proposal for consideration at the November meetings has
been placed on the T10 FTP site as:

< ftp://ftp.t10.org/t10/document.99/99-266r1.pdf >

The text of the proposal is as follows.

Doc:  T10/99-266r1
Date: 17 September 1999
To:   T10 Technical Committee
From: Ralph Weber, LSI Logic Alternate Member of T10
Subj: Description Lengths for 5D ASC/ASCQs

Around half of the 5D/xx descriptions added by 99-217r0 line wrap in
the SPC-2 tables.  The September Working Group disliked the changes
proposed in revision 0 to solve this problem.  So, glutton that I am,
here's a second try.

Change: EXCEEDING DRIVE ERROR THRESHOLD
    To: TOO MANY DRIVE ERRORS

Change: DATA ERROR RATE EXCEEDING LIMITS
    To: DATA ERROR RATE TOO HIGH

Change: SEEK ERROR RATE EXCEEDING LIMITS
    To: SEEK ERROR RATE TOO HIGH

Change: ACCESS TIMES EXCEEDING LIMITS
    To: ACCESS TIMES TOO HIGH

Change: START UNIT TIMES EXCEEDING LIMITS
    To: START UNIT TIMES TOO HIGH

These changes do not affect the English meaning and should translate
to foreign languages at least as well either way.  Making only these
changes will be a big help.

Change: LBA REASSIGNMENT EXCEEDING LIMITS
    To: TOO MANY BLOCK REASSIGNS

This change uses the language of SBC (in the REASSIGN BLOCKS command)
to shorten the ASC/ASCQ description to something that will fit in all
current cases, and many of the potential future cases identified by
the working group.

Change: FAILURE INDICATED BY CHANNEL PARAMETRICS
    To: FAILURE CHANNEL PARAMETRICS

This change may seem like it's removing information, but it's really
bringing the form of one description in general alignment with its
neighbors.  Here are some examples:

5Dh/17h HARDWARE IMPENDING FAILURE INDICATED BY CHANNEL PARAMETRICS
would become:
5Dh/17h HARDWARE IMPENDING FAILURE CHANNEL PARAMETRICS
matching:
5Dh/18h HARDWARE IMPENDING FAILURE CONTROLLER DETECTED
5Dh/19h HARDWARE IMPENDING FAILURE THROUGHPUT PERFORMANCE
5Dh/1Ah HARDWARE IMPENDING FAILURE SEEK TIME PERFORMANCE
