I have not been able to find a decoder for the EF51 error information in this

HISTRY or PARAMS>stat log do not provide any clues.
The drive seems to log errors at the rate of two per day, and usually
fairly close together.

I have checked the ESE50 service guide for longword decoding, however
it only works on longwords #1, and #2 (both '00000000' in this case) but does
not deal with longword#3 which is the only one I have with any bits set.
Any help with either decoding the information, or a pointer to a
resource would be welcome.
Regards...
Dave Clark

If the 37 in those longwords is the DER code then 37 = Replace Old Battery.
You may be running slow because ALL I/O is going to the retention device and NOT
to RAM.
I've attached a BLITZ I sent out about a year ago and resent recently to the
Field.

DESCRIPTION OF SERVICE ACTIVITY REQUESTED (if applicable):
**********************************************************************
SYMPTOM:
Customer can lose all data contained on Solid State Disks during
power failure if the retention battery has failed.
PROBLEM STATEMENT:
The mode in which NiCad batteries (as those used in the EF5xR
products) most commonly fail, is that they will test as having
voltage and current, however, in fact they can be holding next to no
reserve. This, if left undetected in a EF5xR implementation can render
the drive in a state that is only recovered by reformatting the unit.
It was for this reason that the EF5xR family of devices has on-board
battery test diagnostics, and that the batteries must be tested and
replaced every three years or if diagnostics fail during a yearly
test as part of normal service procedure.
SOLUTION:
Replace any batteries that are 3 years old or fail annual battery
tests.
Inspection of the battery manufacture date, located on the battery
label is the only true way of finding out the age of the battery.
Refer to section 4 of EK-EF5XX-UG for proper procedures to access
and run BATTST utility.
NOTE: As per section 4 of EK-EF5XX-UG, you may view how many days the
current battery has left before the 3 year replacement by looking at
the PARAMS values of BSS_MAXR and BSS_REPL. BSS_MAXR is the total
number of days a battery can live before proactive replacement and
BSS_REPL is number of days left on current battery. Once BSS_REPL
reaches "0" the unit will issue an errorlog datagram with a DER code
of 37(x) (Replace Old Battery) once per week.
Refer to section 7 of the EK-EZ5XX-UG for proper procedures to
replace a battery pack (The EF5XX User Guide omits the actual
replacement procedure).
Note: Both of the manuals are available online at;
SUBSYS::LCA:[SPECS.SOLID_STATE.EZXX] or,
SUBSYS::LCA:[SPECS.SOLID_STATE.EFXX] or,
TIMA TOOLS in .PDF and .PS format
Note: The replacement battery part number has recently been CHANGED!
OLD battery pack PN# 12-37620-01
NEW battery pack PN# 29-33445-01
These batteries may discharge during storage and at times when the
unit's power is removed for more than a month. Upon initial receipt
of a new EF5xR or after replacement of the batteries in an existing
EF5xR, you may find the device is write protected due to insufficient
battery charge-level for data retention. It is recommended that EF5xR
devices be powered on for a minimum of four hours before operating.
EF5xR batteries must be replaced every 3 years as part of normal
service procedure. This item is considered a "wearable" item and NOT
covered under warranty or field contract. Any replacement is the
responsibility of the user and should be charged per call/time and
material.
Once the battery pack has been replaced on a EF5XX, you must reset
the internal battery 3 year counter saved in the parameters of the
device. BSS_REPL (as mentioned above) is a read only word, and to
reset it to factory default of 1095 (3 years in days) you must write
a "1" into parameter BSS_REST (this may take a minute to be detected
by the firmware). Then, either power cycle the unit or set the bit
BSS_UPNV (Update Non-volitile) to force it take an immediate effect.
VERIFICATION:
After battery has had sufficient charge time, a successful pass of
BATTST indicates a good battery.
It is also a good idea inspect the EF5X battery pack for visible
signs of "leakage" whenever service is performed on the unit.

Your welcome. That DECevent log looks strange. Can you copy a binary of that
error to BOT000::FIREWALL: so I can bit bust it manually?
roger.

| 3922.7 | File copied as requested | KERNEL::CLARK | STRUGGLING AGAINST GRAVITY... | Thu Mar 13 1997 06:18 | 8 |
| Roger...
The file EF51_ERRORS.BIN is now copied as requested. This is the
cluster-merged binary errorlog for the device since 1st march this
year.
Sorry about the delay...I had a day off yesterday (12th)

I did not have to break them down. Why? If you notice, the errors happen every
24 hours.
The drive tests the battery status every 24 hours after being powered up, if it
fails, your get the every 24 hr error message.
Every 7 days after power on, the drive also test's the internal value of
BSS_REPL and if = 0, will also issue the same error packet, except 7 days appart.
