问题描述

  • LUN或卷上的写入工作负载增加
  • 虽然延迟非常明显:
  • [*> node run -node <node_name>-command "priv set diag;systat -x"]显示:
  • 100% CPU
  • 列:[ CP_Ty ]标记为:B (背靠背一致点)
  • [*> node run -node <node_name>-command "priv set diag;systat -M 1"]显示high [ Nwk_exexexus]
  • 平台为全SAN阵列(ASA)
  • 在All充实的FAS (AFF)上、类似的工作负载的行为似乎有所不同
