Grading Checklist

• Identified the RAID controller model from lspci and recognized it needs a specific driver
• Understood that the inbox kernel in the installer ISO lacks the megaraid_sas module for this newer controller revision
• Proposed using a Driver Update Disk (DUD) to inject the driver during installation
• Described the DUD loading process (boot with inst.dd or linux dd kernel parameter)
• Mentioned checking Lenovo or Broadcom support sites for the correct DUD ISO
• Considered alternative: using a Lenovo custom ISO with pre-integrated drivers
• Considered alternative: switching to JBOD/HBA mode if the use case allows it
• Verified the RAID virtual disk is properly configured and initialized in the controller BIOS
• Checked dmesg in the installer shell for driver binding errors
• Mentioned testing the DUD in a non-production context before fleet-wide deployment
• Addressed the need to update the standard build ISO or kickstart to include this driver for future installs
