RE: AW: Slashdiot article about P6

It was a number of years ago at my previous employer and I got a call at
home on the weekend from IBM that a drive had failed. It was one of the
mirrored load source drives. I think that was at V3R1 and we were always
very current with hardware and software there. Well the failed load source
drive was in and the rebuild started and - all hell broke loose and the
system died/hung. Rochester walked me through a slip install way back then
and all was fine. Only took maybe an hour on a very large system.

On a side not - if you know the system and understand the setup, that was a
MAJOR blowup back then and IBM was in the systems for weeks trying to figure
out what the heck happened.

And the system is highly "SUT" (stupid user tolerant).  I misread the
documentation, and attempted to load an entire set of cumes and group PTFs
at one time.  The link loader blew up; I had loaded too many PTFs.

A failure of this magnitude on just about any other operating system would
involve at the very least rebuilding the machine from scratch and probably
reinstalling all software and reloading the last data backup as well.

With OS/400, I called IBM and they walked me through "slipping the LIC" -
basically, reloading the operating system UNDERNEATH all the application
data.  After about an hour and a half, I was good to go without touching a
single backup tape.

I then reapplied my cumes and groups according to the directions, and didn't
get a hiccup.
