问题描述

每个 iSCSI 节点都必须具有一个节点名称。节点名称通常采用 iSCSI 限定名称( IQN )格式。  此标准是行业标准, NetApp 需要此标准。  iqn 类型指示符是一个逻辑名称,它不与 IP 地址关联。

下面是一个示例格式:

iqn.yyyymm.backward-naming-authority:unique-device-name

yyyy-mm 为命名机构获得域名的月份和年份。

' 向后命名授权机构 ' 是负责命名此设备的实体的反向域名。反向域名的示例为“ com.microsoft ”。

“ unique-device-name ”是由命名机构为此设备指定的自由格式唯一名称。

以下示例显示了用作应用程序服务器的某个启动程序的 iSCSI 节点名称:

iqn.1991-05.com.microsoft:example

注:某些启动程序可能会提供上述格式的变体。

将 iSCSI 主机与 Data ONTAP 启动程序组( IGroup )关联以将 LUN 映射到主机时,会使用 iSCSI 启动程序节点名称。
