 Hi everyone;

I think I've found a bug. While it isn't that huge and it doesn't impact
me at the present time, I'm curious if anyone else can duplicate what
I've observed.

Some background: I have two 3960's each with 12TB raw storage. I've
recently begun receiving some error messages from one of the 3960's
inidicating that I have a battery fault condition in a T3 partner pair.
Of course I've followed up and have taken a closer look at the T3's. In
doing this I've manually issued a "refresh -s" to the T3 partner pair in
question. For the purposes of this email I'm looking at only t3b0 on each
of the 3960's.

Both 3960's have been powered on for the same length of time and any
clock skew (in either the MSP or the individual T3's) will be the same
within each of the units.

In the first instance (t3b0, 3960 #1) I have a clock skew in the battery
life of ~229 days. In the other unit (t3b0, 3960 #2) I have a clock skew
in the battery life ~59 days. It appears that u2pcu1 and u2pcu2 are
either more heavily loaded as the output from both sets of partner pairs
is in relative agreement. Outputs from each t3b0 partner pair follows.
I'm curious about "Battery Life Used", in one case also the serial number
skew. Scratching my head.
