Actually cpu0 panic : uncorrectable machine error
was Hardware Error, The problem Found on memory after replacing memory
boards and monitoring for 2 weeks the server worked fine
I thought there might be diagnostics CD to make Full Hardware Test, but you
can run test command from >>> to test HW.
>>>test
related to log files; we can make use of the following
/var/adm/messages " for ASCII
error LOG"
/usr/sbin/uerf -t s:01-apr-2002 e:11-apr-2002 " for Binary error LOG"
/var/adm/crash/crash-data.nn " Crash File"
not only uerf used to analyze /var/adm/binary.errlog log file also we can
use uerf/dia/ca
we can using Compaq Analyzer (ca),"ca x analyse".
or dia -R
kernel debugging can be used to collect more information refer to kernel
debugging book
2 files are copied "other than crash-data.nn "used in analyzing crash in
/var/adm/crash/
kernel and crash dump; "But I think it is complex way"
Thanks again to all how responded
