| 1242.1 | Does 3.1 really help? | PFSVAX::WUENSCHELL | | Wed Apr 30 1997 08:15 | 7 |
| Keith;
We continue to fight battery failures in the field even with
batteries dated 97. Are you continuing to have good results with HSOF
3.1? If so, this may be a solution for some of our problem customers.
By the way, are there any patches to 3.1 that you know of? A note in
this conference says there aren't, but then I saw a reference to 3.1-6.

| 1242.2 | | SSDEVO::THOMPSON | Paul Thompson, Colorado Springs | Wed Apr 30 1997 13:35 | 5 |
| Do the 1997 batteries with which you are having problems have white labels?
If so, the manufacturing date of those batteries pre-dates 1997. The date
on the white label shows the date that the battery was most recently
re-charged.
|
| 1242.3 | White label has MAR 1997 | PFSVAX::WUENSCHELL | | Thu May 01 1997 07:57 | 6 |
| Yes, the batteries have a white label with Mar 1997 on it. They also
have MAR 97 stamped in black on the edge.
Are you saying that these batteries may have problems? How do we
determine which 1997 batteries are good or bad?
|
| 1242.4 | Batteries WITHOUT white labels | SSDEVO::THOMPSON | Paul Thompson, Colorado Springs | Thu May 01 1997 14:32 | 4 |
| Batteries dated 1997 that do not have a white label on the face of the battery
with this date are good. Batteries with the date on a white label on the face
of the battery were originally manufactured in 1996 and are subject to the
problem from the vendor's manufacturing defect.

| RE: .5
OK, I accept your challenge.
I presume the questions in .0 that you would like answered are the
following:
>>
>> The strange thing was
>> that the next mornng the HSJ reported the battery as good with the
>> added message of "Cache battery is now sufficiently charged". Can
>> someone explain this?
>>
Yes, I can. This entire battery problem has been extremely painful
for everyone. It has been caused by several problems, both hardware
and software.
Major changes were made to the battery diagnostic in V3.1 which
specifically corrected many of the software issues. We know now that
the diagnostic in V2.7 and V3.0 was declaring many batteries "failed"
when there was no problem with them at all. One of our tests here
in the past few days was with a set of batteries which failed
consistently on V3.0 and passed consistently on V3.1. These
batteries have a date code of 10/94 and our testing shows that they
would still hold up a cache for 70 - 80 hours!!
Keep in mind, however, some of the failures detected by the software
were true battery failures. The big problem was to eliminate the
"false" failures while still detecting true failures.
>>
>> Have we been replacing batteries like mad because
>> the old battery testing routine was bad (despite the patch)?
>>
As I mentioned above, some, but not all, of the problems were due
to the software falsely declaring some batteries bad.
>>
>> As there
>> is always some delay in getting all our customers up to V3.1 is there a
>> better patch we can apply to V2.7 to facilitate the same response.
>>
NO.
>>
>> OR
>> (heaven forbid :-) ) has the battery test been fudged to cope with all
>> these failing batteries??
>>
I hope this suggestion was entirely facetious. But if there is any
doubt, NO!!!, the test was NOT fudged simply to pass all batteries,
bad ones included. Many MONTHS of effort by both hardware and
software people have been spent trying to resolve this serious
customer satisfaction problem. No one here has treated it lightly.
The changes in V3.1 were a big step. However, more work is going
on now. This issue is still not closed to our satisfaction.
Hope this helps.

| Tom,
Thanks for the reply. Not the one I wanted but at least it is an honest
one and we know where we are.
Oh and by the way the last part was facetious but I didn't know the
symbol for "tongue in cheek". [ :-Q maybe??]

| 1242.8 | Cache Battery Low Messages | BSS::BERGLING | | Thu May 22 1997 09:15 | 11 |
| I have a new twist on this.
We have installed 3.1 on about 26 HSJ40's. We are getting cache battery
low notices. When we check the J later, like 8 hours later it says:
"Cache battery is now sufficiently charged"
Any explanation for this?
Thanks,
Vern Bergling
|
| 1242.9 | Normal operation from what you describe | SSDEVO::RMCLEAN | | Thu May 22 1997 09:49 | 4 |
| Yup... When you get batteries or if you have batteries that have been supporting
the cache there is some chance that they have been discharged somewhat.
Batteries sitting on the shelf or in an unpowered module discharge naturally.
The starting low and later becoming charged is perfectly natural.
|
| 1242.10 | Installed Batteries | BSS::BERGLING | | Thu May 22 1997 16:53 | 5 |
| These J's have not reported the batteries being low before. It seems to
be running fine and then gets a low indication. After 8-12 hours this
changes back to normal. Is the HSJ recharging the batteries or what?
Thanks,
|
| 1242.11 | 3.1 Crashes on low Batteries???? | BSS::BERGLING | | Fri May 23 1997 08:42 | 198 |
| The following is a console output from one of these "J"s. It seems that
when we get the first DRAB interrupt the J crashes. It then logs a
number of failure codes all pointing to the cache batteries. 4 hours
later the batteries are again sufficiently charged.
Is this crash a new feature for 3.1?
The batteries will be replaced today.

| The important thing here is what is the date on the batteries? They may well
be very near failure but they should still be able to hold up the cache for
100 hours.
