Re: [foxboro] "SCSI bus DATA IN phase parity error"

The last time i saw this error when i misplaced the SCSIin/out on the
external harddisk.
But ofcourse nobody on this list ever made that mistake, except for me. ;-)

Before that, i had build a SCSI chain which was too long. With the current
speed of SCSI i think you reach the maximum SCSI chain length quite easily.
I don't know the max. length, but you can look into that.

Importance: High


Hi list,

We recently upgraded our server hardware. We had 2*18.2G hdd. Added one more
18.2G hdd.

The hardware configuration details are :

Serial No.      13746540        
Model   UltraAX-MP+ WorkServer  
Processors      2*UltraSPARCII 400MHz   
Memory  2048 MB 
        OpenBoot 3.10.50 ME     
Keyboard        Sun Keyboard    

The current Solaris version installed is 8 and the patch-level is 
SunOS oracleapps 5.8 Generic_108528-08 sun4u sparc SUNW,UltraAX-MP


I tried a re-install of Oracle Applications again this evening. And this
time I used the new harddisk for the DB and not the Technology Stack as per
suggestion. The Technology stack was installed on the old disk ("disk 1").

But, the installation had to be aborted due to "Failed to execute the SQL
script wVIS.sql against %this_DBName%" error. When I checked the details of
the error, it said this :
----------------------------------------------------------------------------
-----------------------------------------------------------------------
Execution Error: wVIS.sql

   (/d01/app/oravis/product/805/orainst/apps/orainst/appcweb.log) for

I looked up the error on the web for "SCSI bus DATA IN phase parity error" :

----------------------------------------------------------------------------
----------------------------------------------------------------------------
----------------------------------------------------------------------------
----
Cause
The most common cause of this problem is unapproved hardware. Some SCSI
devices for the PC market do not meet the high I/O speed requirements for
the
UNIX market. Other possible causes of this problem are improper cabling or
termination, and power fluctuations. Data corruption is possible but
unlikely to occur,
because this parity error prevents data transfer.
Action
Check that all SCSI devices on the bus are Sun-approved hardware. Then
verify that all cables measure no longer than six meters, total, and that
all SCSI
connections are properly terminated. If power fluctuations are occurring,
invest in an uninterruptible power supply.
----------------------------------------------------------------------------
----------------------------------------------------------------------------
----------------------------------------------------------------------------
------
We have the new harddisk that was replaced recently. The model No. is
ST318406LC, whereas both our existing hdds are ST318404LC. In myt opinion
this could be the problem. In the meantime, I am also tried to get the
"hardware compatibility list" for the model we have. But, since this is not
a "branded"  server, it is not listed anywhere and may be difficult to get. 
Can anybody confirm that this error is due to hardware incompatibility and
not application or what is it that is causing this problem?

Thanks
Varsha
