How to export DHCP reservations in Windows 2008 R2
Export the DHCP reservations, from the Old server which is to be migrated using netsh:
netsh dhcp server [ip address] scope [scope address] dump>c:\temp\reservations.txt
e.g. netsh dhcp server 172.20.2.33 scope 172.16.0.0 dump>c:\temp\reservations.txt

Normally this is an issue when you have a piece of hardware causing constant errors, which ends up filling the logs. With RHEL, if you have Open Manage installed you can run the following:
omconfig system esmlog action=clear
omconfig can be found in /opt/dell/srvadmin/sbin/
So you can just run this command and then it is clear.
# /opt/dell/srvadmin/sbin/omconfig system esmlog action=clear
After clearing. recheck the log to see what error is actually occurring. If it is a dimm, which is likely, power down and swap it with another location and then see if the error follows the dimm or the slot.. If it follows, then you know the dimm is to blame.
Here's a quick command script for version 6.5
"C:\Program Files (x86)\Dell\SysMgt\oma\bin\omconfig" system esmlog action=clear
