Opened: Nov 03, 2017
Severity: 3-Major

Symptoms

Unexpected warnings in the LTM log indicating Octeon, Nitrox, and/or Super IO recovery happening in BIOS. Messages appear similar to the following: -- warning chmand[5972]: 012a0004:4: Nitrox recoveries: 1 -- warning chmand[5972]: 012a0004:4: Octeon recoveries: 1 -- warning chmand[6018]: 012a0004:4: Host CPU subsystem power-off event caused by Super IO

Impact

There is no functional impact to the system. The BIOS shipping with the VIPRION B2150 and B2250 blades configures the PCIe interfaces in such an order that BIOS recovery may have to take over. These messages are generated as BIOS error recovery is implemented to correct the PCIe interfaces configuration issues after which the system will boot normally. These messages are then benign.

Conditions

-- Currently released BIOS with error recovery enabled. -- VIPRION B2150 and B2250 blades.

Workaround

These are benign messages in the LTM and shows that BIOS error recovery is working. The messages may be ignored.

Fix Information

None
