  • ONTAP 9.7P5
  • CRC 错误

问题

在 EMS 中观察到以下错误:

Fri Jun 26 01:10:33 [nodeA: vifmgr: vifmgr.cluscheck.crcerrors:alert]: Port e0c on node nodeA is reporting a high number of observed hardware errors, possibly CRC errors.

由于板载千兆以太网 NIC 端口上的队列溢出,用于传输的帧丢弃量增加:

::> system node run -node <node_name> -command ifstat -a 

TRANSMIT
Total frames:    97068k | Frames/second:     562  | Total bytes:       146g
Bytes/second:      847k | Total errors:        0  | Errors/minute:       0
Total discards:    432k | Queue overflow:    432k | Multi/broadcast:  5776
