适用场景

  • ONTAP 9
  • CRC错误

问题描述

  • 由于集群端口上的CRC接收端错误过多、持续发生"可能的缓冲区溢出"崩溃。  如果数据量超过内存缓冲区的存储容量、则会发生缓冲区溢出(或缓冲区溢出)。
     示例：
     panic：在进程NwkThd_00中、PC 0xffffff8a084139 (fencePOST 0x3)中的地址0xfff83fa2aa4820可能发生缓冲区溢出
  • 集群端口上的CRC接收端错误也会导致集群网络降级
     示例
     EMS日志：callhome.clus.net.degraded:alert:对于集群网络降级：在端口e1a上检测到CRC错误、请致电主站点
 
  ::> event log show -messagename callhome.clus.net.degraded
