Dell PE1850/2850 RAID array issue with RHEL4

[Hansjörg Maurer]

Hi

we had stability issues with a perc4di to.
One week of Dell hardware support (Firmware, omsa logs etc) has no results.
(including Level Trier 3 Logs, and Omsa Logs)

The next week, we got conntact to another dell technical supporter, who 
gave us
an linttylog program (according to google availabel form here ...)

http://www.firehat.org/repodata/repoview/linttylog-0-1.00-0.html

It detects
CC Error: Multi-Bit Read error from Secondary ATU, addr=d786cb00, 
syndrome=57 [bit=-1]
^MMulti-bit or overflow encountered (mcisr=1)...shutting down
^MTotal ecc errors encountered this boot=2
^M^M

which occurs the same time linux dies.
Dell changes the Mainboard and the Controller RAM afterwards, and we are 
hoping,
that this solves the problem.
The server has been running for 3 years, but ther error occurs first time
after migrating 1000's of rrd files files to the raid1 disk which are 
updated
often, so that there is much more IO....

I would try to use this tool to check for HW Errors on the controller 
side....

Greetings

Hansjörg
