ONTAP 

RHEL/OEL 

Oracle ASM

问题

  • 在映射到 RHEL/OEL 服务器的 LUN 上观察到远程操作、这些服务器使用 Oracle ASM 作为卷管理器。
  • 即使根据 NetApp 最佳实践在主机上设置了多路径参数,也会发现该问题。

以下命令输出显示远程操作:

cluster1::*> statistics show-periodic -object lun -vserver svm_win -instance /vol/vol_win/lun1 -counter total_ops|remote_ops|remote_bytes
cluster1: lun./vol/vol_win/lun1: 5/18/2020 22:02:26
   remote   remote    total
    bytes      ops      ops
 -------- -------- --------
      35B        2        2
      29B        1        1
      31B        3        3
      26B        2        2
