Hi all,
many thanks to all who responded, especially Rob Leadbeater and Jay Vlack. They mentioned two possible known causes of the problem:
1. (Rob - I quote him):
-----------------------
The disk that you have is a BF03665223. These are 15K RPM 36GB Fujitsu disks with which there are known problems - we had a whole bunch of them which Compaq replaced with Seagate drives, after seeing similar problems.
To quote Compaq support:
"A problem within the HDD build process was found to effect a limited
quantity of BF03665223 disk drives built prior to June, 2002. Peripheral
Device Write Faults (01/03/00) are symptomatic of this problem.
BF03665223 drives experiencing PDWF's should be replaced through the
normal logistics process. Logistics supply has been purged of effected
devices. Drives of this model which are returned through logistics will
be screened for this problem."
The part number that you want to be checking for on any replacement disks sent out is BF03664664.
HP Call Reference is 2362033RE.
Our summary:
Please note once more that the problem effected only "a limited quantity of BF03665223 disk drives built prior to June, 2002" !!! We have BF03665223 disk drives with revision number B008 and B014 and HP claims that these revision numbers are OK and there is no reason to change the disks.
2. (Jay):
---------
There were some specific batches of disk drive that had vibration problems in the past.
3. (Others):
------------
Several of you recommended to upgrade ACS to 8.7. HP hasn't done that but has upgraded to 8.6-11.
======================================================
======================================================
Now, we are happy because we have no more thousands of Peripheral Device Write Fault in HSG80. Why? HP changed:
Both of the batteries in HSG (no effect).
Then the IO module, the EMU module and two cables in the shelf (not as much PDWF, but some were there again).
Then (for the third time during three months) the same disk (it finally failed), the new disk is still the BF03665223 rev. B014.
Then both of the new batteries, because both of them failed(!) during two months.
Some of the steps may helped, because at least for two weeks, we have had no PDWF.
With regards,
Martin

Subject: Thousands of Peripheral Device Write Fault in HSG80
Hi all,
for at least two months, we have had the same problem in our EMA12000:
Every hour we get hundreds of "199=Tru64 UNIX CAM Event" and "1197=KGPSA Tru64 UNIX Event" messages from the same disk (disk40000) - it is always a "Information Message Detected (recovered)", but it tells "UNIT ATTENTION - Medium changed or target reset" and "Disk Transfer Error Event" or "Peripheral Device Write Fault". Sometimes a "Low Voltage Condition" message comes from ca. See the ca listing and mail attached below.
Our local HP support changed (one at a time) the disk, both HSG80's, the shelf, both of the shelf power supplies, the firmware (to V86F-11) and the result has been always the same - something is generating many error messages. There has't remained too much to "try to change". HP is happy doing this (so far they didn't escalate the problem, now they finally promised to do this) but our customer with 24x7 operation is very unhappy by these repeating many-hours shutdowns while changing various parts.
Even if this would be not really an error, our ES45 is very busy resolving these messages.
Our EMA configuration is:
A pair of HSG80's in multibus failover mode, software V86F-11
Three split bus shelves
36 GB 15 krpm disks in striped mirror-pairs (mirrored across the shelves)
Because we had problems with another disk40000 in another HSG80 pair, I would like to make "a poll":
Has anybody similar strange problems with disk40000 in EMA12000/MA8000 ?
Does anybody know a cause of these problems? Could it be caused by some vibrations, magnetic field and so on? If so, why are the problems with one disk only?
Best Regards,

Brief Description:
Low Voltage Condition - ASC x03 ASCQ x00
Callout ID:
FF03000100100107
Severity:
2
Reporting Node:
es45
Full Description:
This is a drive detected condition that relates to the
o detection of a marginal voltage condition that occurs
at the time the device is in process id writing
o or a servo voltage correction signal that is exceeding
internal drive designed parameters.
This is typically NOT a drive issue. This is an environmental
or power problem where insufficient voltage is being supplied
to the drive. It is possible that the enclosure is transmitting
mechanical motion to the drive during heavy seek loads. This
can cause the head/arm assembly to have significant problems
in maintaining tight track following margins that are
inherent on write operations versus read operations.
Heavy seek activity with multiple drives, or having a tape
drive operating (lots of +12VDC needed to drive the tape
servo) in the same enclosure with low drive input power is
most likely the problem and needs to be
investigated/addressed.
Drives of Seagate origin, in particular the RZ28M, RZ25L,
RZ29B, and RZ28B have been known to log these events more
often in typical applications.
Consult Blitz TD 1730A and TD 2130-A for more information.
NOTE:
For FRU codes of 01, 02, 07, 09, 0A and 0B refer to Blitz TD
1730 as these are Input Power Problem related codes.
For FRU codes of 00 or 11(hex), you might wish to verify or
order and install vibration dampening material that would be
put on an SBB by ordering kit part number 70-32877-01
from Field Service Logistics. This kit contains enough material
to modify 7 SBBs. Refer to Blitz TD 2130A (or later rev).
The Reported FRU code that is printed in the event log for
the specific event will decode as follows:
0x01 Format Write Fault (Position Error)
0x02 Format Voltage Fault
0x07 Format Servo Write Fault
0x09 Verify Servo Write Fault
0x0A Verify Servo Voltage Fault
0x0B Voltage Write Fault
