Cisco Bug: CSCvw03252 - fNIC/vHBA QError Handler is not getting processed in time
Oct 13, 2020
- Cisco Unified Computing System
Known Affected Releases
Symptom: Host systems which are using FCoE storage may start experiencing slowness and over time total loss of storage connectivity due to exchange resources used on firmware side may start leaking as a result of qerrors which are not getting processed in time. Conditions: Un-grace full host reboots due to power failure or user action when Write IO is in progress may result in Qerrors. Any PCIe errors or internal bus errors (transient in nature) during DMA operations related to write IOs would result in exchange WQ errors.
