RE: 170 - Power it off or keep it powered on?

Are we not mixing apples and oranges?

You have 70 days to enter a system password once it tells you that a you
need another one. But, I have machines we don't power up but once a year,
and they never ask for a password (V4R5 and V5R1, and maybe one is at V5R2
as well). Now, I can see that the cache battery may be another issue if you
don't power it up for a while, and that could run out. Hopefully the
machine came down smoothly and everything was written from the controllers
cache to disk.

For the sake of being "green", I wouldn't keep a machine up that isn't being
used. I would power it off when not in use. The suggestion about putting
it on a power schedule was a good idea as well.

Perhaps just too many upgrades this weekend is making my mind soft.

Bonnie,

I've heard that somewhere along the line (forget which VxR it was), but
think it was V4) that if the system was not powered on after so many
days (30? 60?) that, when you did power it on it said something about
the license was expired. You can set up a power on/off schedule (GO
POWER) to automatically bring it up for , say, 30 minutes and then power
itself off on a regular basis. (And, if it's sitting in someone else's
office, you might schedule this in the middle of some day just for kicks
and grins - otherwise late at night should do.)

IIRC, the system password (key) has always been around (V1+), but not
enforced till V2R3. 70 days is what I remember, but it's possible the
expiration period may not be fixed or has changed with different
version/releases.

I got a V5R2 170 that I power up every other week. So far no problems.
V3/V4 150s are apparently exempt.
