Grading Checklist

• Reviewed BMC/iDRAC system event log for the exact event type (power cycle vs. reset vs. OS shutdown)
• Distinguished between OS-level crash and hardware-level power cycle
• Checked mcelog for uncorrectable memory errors and correlated with reboot timestamps
• Investigated PSU health and power event logs
• Verified kdump is configured and explained why it may not capture this type of failure
• Considered hardware causes: failing PSU, loose power cable, bad memory DIMM
• Checked for thermal throttling or shutdown events
• Reviewed BIOS settings for behavior on uncorrectable errors
• Proposed diagnostic steps: run memory diagnostics, swap suspect DIMM, check PSU redundancy
• Addressed the database impact and recommended failover while diagnosing
• Considered firmware/BIOS update as part of the resolution
• Mentioned physical inspection: power cable seating, PSU seating, DIMM seating
