As far as the PTF's were you talking about loading all cumes, and groups,
while the system was running; and later doing the PWRDWNSYS to actually
apply them?  I suppose we could do that.  That might help a little.

What we've been doing, however is:
- Get system to restricted state.
- Do complete backup
- Load all cumes and groups.
- IPL.

What we would be cutting out by loading the Cd's whilst the system was
running would be about a half hour to an hour.  For this advantage we
would lose the complete save prior to the loading of the PTF's.  This
could be a problem.  Because if you ever do a complete restore, and a ptf
was in error, you'd have to do your restore, and a RMVPTF, prior to any
IPL or you'd be back in the same boat.  And after having a MF ptf just
last week that invalidated my system password, I am not so anxious to do
that.

Comments?

We are looking at hooking up a separate twinax device for each partition.

Our customers are about split on the console issue.  The ones that do not
have tight card configurations for the LPARs driving them to add
additional
IOPs (and potentially additional towers) are opting for Twinaxial
consoles,
because they always work.  Ops console is also very good, and I won't
hesitate to use it, but it does rely on Windoze communications.

If you have the room for an additional ethernet card, I would go with the
best of all worlds.  Use Twinaxial console, and LAN console.  That way you
can have an honest console at your desk for all four partitions, and use
twinaxial when needed.  When you VPN into the network from home, you
should
have all of the function that you would normally need as well.

Regarding your down time to apply PTFs.  Why not apply all of them at one
time?  Since you have correctly pointed out that you have to power down
the
secondary LPARs when you IPL the primary, why not do them all at once?

One other thought.  You will need to get very good with Management Central
and all of iSeries Navigator.  That is where the action is for most of the
administration things you will be needing.

One last thought, do not let anyone talk you out of the thin primary
partition. (one that only manages the machine, and has no user workload).
Believe me it is the best way to go.
