In SCSI Enclosure Services - 2 (SES-2), the Enclosure Control/Enclosure
Status diagnostic pages and the Array Control/Array Status diagnostic
pages each support Device elements.  The Array diagnostic page versions
are supersets of the Enclosure diagnostic page versions.  When they =
have
shared fields, they are supposed to be functionally ORed together.

This is a rather awkward way to support a few additional bits.=20

Would anyone have a problem with:=20
1. Obsolete the Array Control and Array Status diagnostic pages=20
2. Get rid of the Device element format for the Array diagnostic pages. =

3. Define a new Array element which contains the unique bits.=20
4. Include the new Array element among the other non-Device elements
accessed via the Enclosure Control/Enclosure Status diagnostic page.

Does anyone actually use the Array Control/Status diagnostic pages
today?=20
