There is a alarm like “The number of bit errors on iSCSI host port (engine ENG0, ISCSI interface module A5, port ID P1) is large. The system performance may be affected.”
1． Collect logs. And open running-data.txt file.
Find the same port in logs and remember IP address
2． Open msg_other\Other\ifconfig file and search IP address which found in step1.
3. Check the RX packets. We can know overruns number is 60604 which means IO
from host port is too fast and this is caused by switch doesn’t enable flow control.
Switch doesn’t enable flow control.
Enable flow control in switch view by command: symmetric-flow-control enable.
