Grading Checklist: iDRAC Unreachable, OS Up

A good response must include:

• Used ipmitool lan print 1 from the host OS to check BMC network config
• Verified BMC is responsive locally via ipmitool mc info or ipmitool bmc info
• Checked for IP conflicts using arping or ARP table inspection on the management switch
• Verified the dedicated management NIC link state (switch port status)
• Considered a BMC cold reset via ipmitool mc reset cold as a remediation step
• Checked if VLAN tagging on the BMC matches the switch port configuration
• Verified gateway and subnet mask are correct in the BMC network config
• Ruled out switch-side issues (port disabled, STP blocking, ACL)
• Assessed impact of a BMC reset (does not affect running OS)
• Documented the recovery steps and root cause for future reference
• Mentioned that physical access / remote hands is a fallback option
• Proposed monitoring improvements (BMC ping check, IPMI polling)
