A Troubleshooting
1. When customer logs in to an iDRAC, a SEL event is found mentioning that iDRAC has failed to verify
BIOS, but host booted successfully.
• This event is part of iDRAC HW RoT, even after a failed BIOS image verification, iDRAC performs a
recovery operation to bring good BIOS image.
2. Host is booted to operating system, but the host has no network access to due to a timeout.
• When BMC does not come up to perform HW RoT, the system is built with mechanism to detect this
condition. The system then performs a safe boot for the host.
3. The BIOS booting fails due to BIOS image integrity check failure, and the subsequent BIOS recovery
fails. Use the following mechanism can be used to recover the BIOS manually.
• Upload the BIOS DUP from any of the iDRAC interfaces (for example: iDRAC UI).
• Perform the racadm BIOS recover command as mentioned in Section 2 of this document.
