Subject: PERC3/Di reset on 2650 server running Red Hat 7.3



Hi, 

We have three Dell PowerEdge 2650 systems running RedHat 7.3 that are used
exclusively as MySQL server. 
During startup of our system, several gigabytes of data are retrieved from
the SQL server. 

Two of our servers sometimes fail with the following message: 
      "aacraid: Host adapter reset request. SCSI hang ?" 
After this message, we get loads of error messages from the EXT3 filesystem
(it is not possible to access the filesystem anymore). 

Before we get this message, the disc activity already seems to have halted
for more than 10 seconds (the activity LEDs are not flashing any more). 

The configuration of the servers that show the problem as follows: 
- 2 x Pentium 2.4 
- 2GB internal memory 
- 5x70GB harddrive (RAID5) 
- Additional Intel PRO/100S network adapter 

The 2650 that does not show the problem does not have the additional network
adapter. The configuration of the RAID controller is the 
same for all three 2650 servers. The problem occurs for both the
2.4.18-19.7.xsmp kernel and the 2.4.18-27.7.xsmp kernel. 

The 2650 system were installed with the standard RedHat CDs (obtained via
DELL), after which I installed the RedHat 
updates (using the rpm -Fvh *.rpm) command. 

I experimented with a RedHat installation (from the standard CDs) on which I
only installed an updated kernel (I did this with kernel 2.4.18-4.smp 
and 2.4.18-27.7.xsmp). 
I did not manager to reproduce the probem on these configurations. As soon
as I installed the remaining updates, the problem occurred again. 
However, it takes some time (10 minutes .. 25 hours) and 'luck' to reproduce
the problem, so I am not sure whether the absence of the probem 
has anything to do with not installing the RedHat updates. 

Any explanation or solution would be most welcome! 


Eric.
