1905.0. "Long KZPSC init on 2 vol RZ29 stripeset?" by PTOSS1::CYPHER () Fri Mar 21 1997 16:00

    I installed one each single-channel KZPSC in seven AlphaStation
    500 5/400 systems. Each has 4mb cache with no battery and drives
    a split-shelf BA356 with 2 RZ29B-VW disks. We built and init'd each
    as a RAID-0 stripeset and went home for the weekend, returning to
    completed operations on Monday. One required a re-do and I timed
    it at 20 hours! Any clue as to the seemingly long init time?
    I double checked the SRM FW to be 6.3-11 (3.8CD). I upgraded to 6.4-3
    from the 3.9CD. No help. All seven of my machines seem to exhibit this
    behavior. KZPSC-XA rev D / Standalone RCU V3.2 / Config util 3.11 /
    SWXCR FW 2.36 / 4mb cache / no battery / "write-thru" mode. Moved a
    second module into the box; no help. Started init & saw following:
    	20 minutes	11% complete
    	60 minutes	21% complete
    	90 minutes	26% complete
    The time seems to lengthen with progression. The led's seem to indicate
    an RTZ is being performed between writes, as opposed to a spiral write.
    This would account for worsening times. I will cross-post in the
    ALPHASTATION notesfile. Systems are PB560 (Alphastation 500/400mhz).
    
    Thank you,
    Dennis
