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

["Pete Massiello" <pmassiello-ml@xxxxxxxxxxxx>]

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.

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.
