A Troubleshooting
1. When logged into iDRAC, a SEL event notifies the user that iDRAC has failed to verify BIOS, but host
booted successfully.
• This is part of iDRAC HW RoT. Even after a failed BIOS image verification, iDRAC performs a
recovery operation to bring good BIOS image.
2. The host is booted to the operating system, but it took longer, and host has no network access.
• When the BMC doesn’t come up to perform HW RoT, the system’s integrated mechanism detects the
condition and performs a safe boot for the host.
3. If the BIOS booting fails due to BIOS image integrity check failure, and if subsequent BIOS recovery fails,
then the following mechanism can be used to recover the BIOS manually:
• Upload the BIOS DUP from any of the iDRAC interfaces (e.g.: iDRAC GUI).
• Perform the racadm BIOS recover command as mentioned in Section 2 of this document.
