NetApp 共享存储的磁盘所有权

分配或显示 NetApp 共享存储的磁盘所有权

更换磁盘后需要分配磁盘

启用sanown / software基于磁盘的所有权有哪些要求?

NetApp 共享存储遵循基于软件的所有权模型。所有权模型的基础是:

  • 磁盘将明确分配给存储系统
  • 所有权信息将写入磁盘
  • 分配后、存储系统将使用预留来防止其他存储系统与磁盘接触
  • 某些磁盘可能会一直处于非所有状态。无主磁盘无法下载新的固件。
  • 必须分配磁盘以用作备用磁盘

启用软件所有权( Sanown )的要求如下:

  • 支持 SANown 的 Data ONTAP 版本
  • 基于 CompactFlash 引导的文件管理器
  • DS14 、 DS14mk2 机架

要分配 NetApp 共享存储的磁盘所有权:

  • Data ONTAP 8 7-模式  

disk assign <diskname> [-f] [-p ] [- o <ownername>] [-s <sysid>]

    1. 正常使用是将非自有磁盘的所有权分配给本地存储系统:

disk assign 0b.16
disk assign 0b.17 -p 1

    1. 将本地存储系统拥有的磁盘分配回非自有磁盘:

disk assign 0b.16 -s unowned -f

    1. 要将所有权分配给另一个存储系统:

disk assign 0b.16 -o otherguy -f

应使用更高级别的功能( vFiler 迁移)来执行此操作,除非磁盘是备用磁盘

    1. 如果接收存储系统无法与捐赠存储系统进行通信,则会出现有关重新扫描消息的警告。
       
  • Data ONTAP 8 集群模式:
    disk reassign”是一个高级命令。

::> set adv
::*> disk reassign ?
  (storage disk reassign)
  [[-home] <text>]            Current Home Name
  [ -newhome <nodename> ]     New Home Name
  [ -homeid <nvramid> ]       Current Home ID
  [ -newhomeid <nvramid> ]    New Home ID
  [ -force [{true|false}] ]   Force

要显示 NetApp 共享存储的磁盘所有权:

  • Data ONTAP 8 7-模式  

disk show [-o <hostname> | -s <sysid> | -n | -v | -a ]

显示磁盘信息:

  • 具有匹配的所有者名称
  • 具有匹配的系统 ID
  • 不属于任何系统
  • 所有磁盘的详细列表
  • 由任何存储系统拥有

例如、查看每个磁盘的所有权:

cfo-u37> disk show -v

DISK         OWNER                  POOL   SERIAL NUMBER  
------------ -------------          -----  -------------  
9b.19        cfo-u37   (50408384)   Pool0  3HZ6RA1B00007426SWC9

2b.49        cfo-u38   (50408371)   Pool0  3HZ6SD55000074289R4R
3a.22        cfo-u37   (50408384)   Pool0  3HZ6YDGM000074310Z3A
