Purpose:
Leverage memory ECC events in SEL to locate DIMM slots.
Target Audience:
1. FWA-6080 users
2. Capable to run "ipmitool" commands
Steps:
1. Dump SEL via the command.
# ipmitool sel elist -vvv
2. Find memory ECC events, then note every "Event Data".

3. Take Event Data "a04100" for instance. The correctable ECC was caused by H1 DIMM slot.
- "a0", indicates correctable ECC events
- "a1", indicates uncorrectable events
- "4", indicates UMC4. DIMM physically located at "H" slot.
- "1", indicates slot 1.
