SUMMARY: T3 array battery (update)

From: Allan West <>

After my first summary post, I received several more pieces of useful 

There actually is a group within Sun which still carries the batteries. 
They will sell the battery, or the whole power supply. Linda is the 
person to contact, at least for my area. She can probably point others 
to their regional sales teams.

Jeff Germain sent me these instructions for resetting the battery life 
  Here are instructions for replacing *just the battery* in a T3 power 
  These are commands that can be run from the T3 command line that will 
  the battery life counters; otherwise the system doesn't recognize the 
  that the battery was changed.  Note that these commands should only 
be used
  when changing only the battery -- if you change out the whole power 
  the unit automatically updates the battery settings.

  Here are the commands from the "SunStorEdge T3+ Array Field Service 
  >id read u1pcu1             <-- see the settings before doing anything
  >.bat -n u1pcu1             <-- reset the "Battery Install Week"
  >id read u1pcu1             <-- to see what changed
  >.id write busage u1pcu1    <-- calculate the "Battery Warranty Date" 
                                  "Battery Life Used"
  >id read u1pcu1             <-- to see what changed

which, by the way, shows the official battery life as 730 days and 12 

Tim Thomas said the power suplies can be difficult to remove, and a 
special tool exists to pull them.

Alta Technologies shipped their last in-stock battery to me on 
Wednesday and it arrived today. They are getting more batteries in the 
next couple days.

Another vendor emailed me offering whole power supplies:

I have still not received any response from the "no reply yet" vendors 
I contacted initially.

> 2) Power Supplies are hot swappable and redundant, so you can

> 3) Sun does not sell the batteries separately any longer
> 4) Sun replaces the entire power supply #300-1454, including the
>    battery, under warranty or service contract (I have neither

> 5) several vendors* have or can get the battery pack for $250-$300,
