指定NVME_FEATURE_VALUE_CODES值,指出在提供的數據中傳回的屬性值。 控制器會在識別控制器數據結構的 [選擇性 NVM 命令支援ONCS] 欄位的位 4 中指出是否支援SEL字段。 如果收到 [取得功能] 命令,並將[SEL**] 字段設定為010b(NVME_FEATURE_VALUE_SAVED),而控制器不支援儲存的功能標識符,或目前沒有任何已儲...
首先根据NVMe协议,我们需要用Get/Set Feature Command去设置以下这两个Feature: a) LBA Status Information Attributes Feature。Host有两种方式可以获取LBA Status Information Log Page,一种是Poll,以轮询方式不停地向Controller要求Log Page,此时Get Log 命令中Retain Asynchronous Event bit(保留异步事件比特位)需要保持...

Set Feature 命令支持情况 除了SMART属性之外,主机可以通过Get Features命令获取到关于ES3000 V3工作及健康状态的特性参数。ES3000 V3也可以通过Set Features命令修改NVMe1.2协议中定义的特性参数设置,具体如下: Arbitration(Feature Identifier 01h) Power Management(Feature Identifier 02h) ...
