适用于

  • ONTAP 9
  • FC SAN
  • AIX 主机

问题

  • 主机(AIX)经历了持续的"DISK OPERATION ERROR"事件。
  • 在卷移动(volmove)操作的切换阶段期间或之后立即观察到错误。
  • 映射到单个 AIX 主机的多个 LUN 受到影响。
  • 错误:
    DCB4XXXX 03030xxxxxxx hdisk1data82 DISKOPERATIONERROR
    DCB4XXXX 03030xxxxxxx hdisk1data87 DISKOPERATIONERROR
    ...
  • ONTAP EMS 日志显示重复消息,类似于:
    mgmt.vopl.move.cut.entryFail:error: The volume move operation of volume '<volume name>' ... did not enter the cutover phase. The estimated time to complete cutover is greater than the cutover window that can be tolerated by the user.
  • 注意到存储适配器的 RX 功率低。
  • 注意:ONTAP 升级也可能导致 AIX 主机上的磁盘操作错误,请检查即使在 ONTAP 升级完成后磁盘操作错误是否仍在报告。
