esxi SSD固态硬盘识别问题

   vmware虚拟化，在安装esxi主机时，使用固态硬盘要注意，勿使用服务器的RAID卡配置程序，将硬盘用RAID0配置，否则esxi将不能正确识别出SSD固态硬盘，会作为普通硬盘使用，但在大多数情况下，具体环境并不是这样的，如果做了raid，可以手工进行更改，更改方法如下：

        用SSH连接工具，登陆esxi主机，

输入如下命令

[root@MiWiFi-RM2100-srv:~] esxcli storage nmp device list

重新设置磁盘属性

清除该硬盘的驱动器类型SSD标识：

esxcli storage nmp satp rule remove -s VMW_SATP_LOCAL --device naa.50000396a1b811a9 --option="enable_ssd"

• 1

开启该硬盘的驱动器类型SSD标识：

esxcli storage nmp satp rule add -s VMW_SATP_LOCAL --device naa.50000396a1b811a9 --option="enable_ssd"

• 1

重启ESXI

使用reboot命令或者再控制台点击重启

# esxcli storage nmp device list       

 #列出储存清单（SSD设备的“device name”，

其实可以在GUI内看到；也可以通过“esxcli storage core device list”指令，确认SSD设备的“device name”）

esxcli storage nmp satp rule remove -s VMW_SATP_LOCAL --device naa.6b083fe0ce7f2a0028d86ea311b0e3c6 --option="enable_ssd"  

esxcli storage nmp satp rule add -s VMW_SATP_LOCAL --device naa.6b083fe0ce7f2a0028d86ea311b0e3c6 --option="enable_ssd"     #执行指令，将未识别的SSD设备设置为SSD
