SUMMARY: Issues with T3: Battery and Unmountable Volume

Since I was just able to finish the fixing of the "shadow" volume
recently, this is a long overdue summary:
1. You can use the T3extender.tar.Z can be obtained from Sun to fix
this.  Alternatively, you can use the following commands:

  telnet into T3 as root
  fru stat    (list battery status)
  .bat -n u1pcu1    
  .id write busage u1pcu1 0      (reset battery one)

  .bat -n u1pcu2
  .id write busage u1pcu2 0      (reset battery two)

  refresh -s         (next scheduled refresh, also gives battery status)

2. Wrong position is as it says, it's in the wrong position so just
swapping the disks properly would fix this.
3. For the shadow volume, it was fixed with 'boot -w' but this was
made possible because the T3 was not in production.  Otherwise, one
would need to connect the T3 back to the partner group then unmount it
before removing it.

The negative effect of 'boot -w' is that you would need to set
everything again since it removes volumes, etc.  That means you would
need a console for this.

The following people helped with this:
Govind Kulkarni (T3extender) and Paul Roetman (for the command summary
in the battery).
Mike Busse for the shadow volume.

Thanks again.
