1 - Be careful upgrading the box.  M36, not the S/36 environment, but M36
was dropped in some release.  I think it was V4R5.

2 - Raid is very economical.  We've had them replace several drives here
with RAID protection during the prime time of the day and gave us zero
downtime because of HDD failure.  Downtime is uneconomical.  In fact, I
remember going to a shareholders dinner and telling a president that we
replaced one of their drives today and they never noticed it.  Had a
shareholders meeting today and the president of this division talked
briefly on how the computer runs all the time and also allows targeting of
particular data.  Exception reporting via email instead of piling through
reports....  Looking forward to the dinner tonight.

A question to the Group
                 We have a /170 in one of our branches, V4R4M0, that is
strictly running M36. This was a quick flip from an
advanced machine AS/36 at the same location.
                 Operationally, running ok for about a year now,
                 BUT
                 There is only the occasional Entire system backup, which
in most cases does not coincide with config changes
                 and new equipment is being added at quite a rate.
                 This is a very busy computer, and I was wondering
                 What would be the most economical way of ensuring
up-time, in case of HD failure
                 RAID, or some other method?
Thanks to all
