问题描述

LUN网络地址颁发机构(NAA)编号是LUN的全局唯一标识符。NAA编号可用于确定LUN的序列号、反之亦然。

操作步骤

在7-模式或集群模式Data ONTAP 8™3或更高版本中运行的Data ONTAP包含一个LUN命令,用于以十六进制格式获取LUN序列号:

lun serial -x /vol/test/lun

Serial (hex)#: 0x486e542d4f5a2f47694d684b

以具有以下NAA编号的LUN为例:

naa.60a98000486e542d4f5a2f47694d684b

删除NAA字符串和前8个字符。在此示例中、为naa.60a98000 (这是NetApp供应商标识符之一)。

剩余值(486e542d4f5a2f47694d684b)是十六进制字符串、从十六进制转换为ASCII后、该字符串将成为LUN序列号。有许多基于Web的工具可将十六进制转换为ASCII、如果您使用的Data ONTAP版本没有可用的LUN serial -x命令、则可将十六进制转换为ASCII、反之亦然。

486e542d4f5a2f47694d684b 在十六进制中、将转换为Hnt-oz/GiMhK的ASCII值

您可以 使用命令lun show –v 的输出,也可以查看存储系统AutoSupport输出中的"LUN configuration"部分,根据ASCII格式的LUN序列号确定LUN。

以下是lun show –v 命令的输出示例:

Filer1> lun show -v /vol/test/lun
/vol/test/lun  5g (5368709120)(r/w, online, mapped)
Serial#: HnT-OZ/GiMhK
Share: none
Space Reservation: disabled
Multiprotocol Type: vmware
Maps: test=0

记下上面的LUN序列号(Hnt-0Z/GiMhK)。naa.60a98000486e542d4f5a2f47694d684b的LUN为/vol/test/lun。

注意:有关在VMware ESX环境中识别磁盘的详细信息,请参阅VMware文章1014953

NetApp NAA前缀如下:

集群模式Data ONTAP和Data ONTAP 7-Mode naa.60a98000
集群模式 Data ONTAP naa.600a0980
E 系列 naa.60080e5、 naa.600a098、naa.6d039ea
