Resolution
Solution:
Fortunately, this is a cosmetic issue and has a few options to resolve the error message:
- Option 1: Upgrade to the most recent version of iDRAC7/iDRAC8 firmware (minimally 2.60.60.60) or later version as available per platform.
- Option 2: Ignore the devices from the Host Operating System as this is a cosmetic issue.
- Option 3: If an iDRAC FW 2.60.60.60 or later is not available, optionally rollback the firmware to iDRAC firmware 2.50.50.50
Root Cause:
iDRAC7/iDRAC8 firmware release 2.52.52.52 included a kernel update that introduced this behavior. This is resolved in iDRAC firmware version 2.60.60.60 (minimum version) and later releases as available per platform.
