| This could be many causes. The error log should help understand if
all errors are for a single block, file, area, or random. Is this
error a drive memory error, or a failure during the MSCP compare
function. If the I/O does not have a compare qualifier, then it
is a drive issue. IF the error is a failure of a MSCP data compare
with disk data and host data, it is possible that the host data
is changing before the compare completes. This has been seen with
third party defrag tools, and other third party code.
reviewing the errors logs is a good place to start.

| 308.3 | what were you doing at the time? | SUBSYS::VIDIOT::PATENAUDE | Ask your boss for ARRAY's... | Tue May 13 1997 09:20 | 33 |
| If you mounted the drive with DATA_CHECK READ enabled, OR when running
applications which issue QIO's with the DATA_CHECK modifier. You will
notice Compare errors are logged. It is important to note that no user
data, is lost or corrupted. What you describe is NORMAL behavior on any
DSSI device.
This is due to the fact that MSCP does not require a READ and COMPAREs
to be executed as an atomic operation!
This is also aggravated by disk defragmenting programs, lots of disk I/O
with small files. The problem may also be demonstrated using some programs
that exercise a few blocks without using any type of locking (EX: QIO's vs.
QIOW's). Replacing hardware will NOT FIX this.
Does the Customer run any defrag programs while useing the device for work?
Is the drive mounted or init'd with DATA=WRITE or DATA=READ (or both)?
If the answer to either of the above questions is YES, then what you are
seeing is NORMAL expected behavior.
If the answer is NO, then;
What did you do to recreate this?
Was any hardware replaced?
Do you have any better errorlog analysis tools? (DECevent or SWEAT or FSTerr)
Can you move the errorlog.sys file to a system with a better analysis tool
than VMS 5.5?
Roger.
