Scenario:

  Two month old 270, SStar, 12 8.5G drives, 4G memory, Redundant power and
cooling, 1070 CPW, 0 interactive. Nice cool computer room, whole room UPS.
No foul weather or back hoes in the area.  2:14 AM Monday all is well, no
load on the system. 2:15 AM *POOF* no more box.  22 hrs later it was
determined that two drives failed. Despite the fact that they are in
different RAID sets the system did not handle the failure. One RAID set was
rebuilt when the new drive was added. The second could not be rebuilt as the
set was in "Unknown" status. Rochester said, "Yup, gotta scratch it, sorry."
And we did.

  Unfortunately the Product Activity Log gets scratched in the process so
there is *ZERO history to look at.

  This is NOT what I expect from an iSeries! Can anyone explain a) Why TWO
drives, in different RAID sets and in different cages, would fail
simultaneously without external "intervention" and b) Why a single drive
failure in a RAID set would cause it to fail? Liking this we're not.

ps: IBM has laid off so many people here they had to call a guy in from
vacation to work on the box!
