Here's HSCXX and other controller status...

        Year 2000 Storage compliance including leap year for hardware devices
        __________________________________________________________

A - Do they accept a date from controllers console
B - Receive date information during initialization from host
C - Can they accept dates beyond Dec 31, 1999
D - Roll the date over from Dec 31,1999 to Jan 1, 2000 on internal clock
E - Can they print dates beyond Dec 31, 1999   
F - Can they compute leap years beyond 1996 (29 February 2000)

*  Does not have an internal clock
** reports: 01 March 2000

NOTE:  The KDM70 (which has been EOLed for many years) does not report the 
leap day correctly in the year 2000.  A blitz is being written to inform 
the field of this anomaly and how to correct it. 

17.2HSZ22SIOG::FITZPATRICKTue Mar 25 1997 16:5010
When I researched this earlier this year, I got a reply 
which also mentioned the following :

- The HSZ22 controller which we will be introducing later this year as the
  RAIDarray 350 accepts and displays a two digit date format; however it does
  handle the rollover from 12-31-99 to 01-01-00 and it does treat year 00 as
  a leap year, so I believe it also meets the definition of Year 2000
  compliance, although it will incorrectly treat the year 2100 as a leap year.
