Symptoms

PCIe correctable errors may be infrequently reported on VELOS BX110 blades due to the Train Cold - Run Hot (TCRH) Compensation Feature being triggered in response to platform temperature changes. This feature utilizes a PCIe PHY layer reset to optimizes performance and data integrity as operating conditions change. Examples of the different types of correctable errors that may be reported include any of the following: 1. Bad DLLP 2. Bad TLP 3. Replay timer timeout (RTTO)

Impact

The Train Cold - Run Hot (TCRH) Compensation Feature is an expected behavior on the VELOS BX110 blade and these infrequent correctable errors have no system impact.

Conditions

-- Train Cold - Run Hot (TCRH) Compensation Feature triggered in response to platform temperature changes. -- VELOS BX110 blades.
