Data Domain:DD3300 将磁盘警报映射到正确的硬盘插槽

Summary: 在 Data Domain DD3300 系统上,磁盘故障警报引用机柜和磁盘编号(例如,Enclosure=1:Disk=18)。这些标识符与设备上的物理插槽编号不直接对应。本文介绍如何准确地将警报信息映射到正确的物理磁盘以进行更换。

Instructions

DD3300 使用自定义的 Dell R740xd 平台,其中物理插槽编号从 0 开始,而 Data Domain 软件从 1 开始标识磁盘。在将警报数据与物理磁盘位置关联时,此不匹配会导致混淆。

了解 DD3300 上的插槽编号差异。

  • 物理插槽:从 0 开始。
  • 软件磁盘 ID:从 1 开始(格式: Enclosure.Disk,例如, 1.18)时,此方法起作用。

使用以下图表,根据警报中提供的磁盘标识信息确定要移除的磁盘。
 

正面磁盘(面向一体机正面)
Software ID= disk 1.1

Physical slot = 0 (zero)
Software ID= disk 1.4

Physical slot = 3
Software ID= disk 1.7

Physical slot = 6
Software ID= disk 1.10

Physical slot = 9
Software ID= disk 1.2

Physical slot = 1 
Software ID= disk 1.5

Physical slot = 4
Software ID= disk 1.8

Physical slot =7
Software ID= disk 1.11

Physical slot = 10
Software ID= disk 1.3

Physical slot = 2
Software ID= disk 1.6

Physical slot =5
Software ID= disk 1.9

Physical slot = 8
Software ID= disk 1.12

Physical  slot = 11

 

中间背板磁盘(从一体机正面朝向)
Software ID= disk 1.15

Physical slot = 14
Software ID= disk 1.16

Physical slot = 15
Software ID= disk 1.17

Physical slot = 16
Software ID= disk 1.18

Physical slot = 17

 

背面 SSD(面向一体机背面)
Software ID= disk 1.13

Physical slot = 12
Software ID= disk 1.14
UNUSED for DD3300
Physical slot = 13

 


示例

  •  Data Domain作系统发布了以下磁盘故障警报。
Severity                       CRITICAL
Class                          HardwareFailure
Object                         Enclosure=1:Disk=18                             
Status                         active
Message                        Unable to access a disk and the disk state is missing.
Post Additional Information    EnclosureSerialNumber=NA:DiskSerialNumber=NA:FailureCode=NA
Clear Additional Information
Event Id                       EVT-STORAGE-00002                      
Event Name                     DiskFailure           
Description                    Unable to communicate with a disk. This disk cannot be used at this time.                                       
  • 确定警报中的机柜和插槽信息 --> 在本例中,  Enclosure=1:Disk=18 
  • 参考布局表(上面),以确定哪个物理插槽映射到警报中的机柜和磁盘插槽信息。 
    • 1 个磁盘 18 位于物理插槽 #17 中。 

    还可以使用 CLI(命令行界面)将磁盘警报映射到正确的硬盘驱动器插槽。
    运行以下命令以显示磁盘到插槽映射信息。 

    # alerts show current 
    # disk show hardware detailed

      # alerts show current-detailed

    Severity                       CRITICAL

    重要提示:

    • 请勿使用 disk show state 用于物理硬盘状态;它仅报告虚拟设备状态。
    • 有关重建状态,请使用 iDRAC 进行检查。

    可选:使用磁盘信标。
    要以物理方式找到磁盘,请使用磁盘软件 ID(而不是物理插槽号)闪烁其 LED:

    # disk beacon 1.18
    Press Ctrl+C to stop beaconing.
