我的平台是10400+B460m迫击炮，主板自带2个m2口,6个sata口，其中m2_1位置我安装了一个转出5*sata口的JMB58x转接卡，可以免驱。 unraid下新建dsm虚拟机，分配了引导盘之外没有任何虚拟盘，而是把m2口的转接卡直通给了虚拟机。 虚拟机的配置如图： unraid下可以把img引导盘虚拟成USB设备，因此引导盘在群晖里是隐藏看不到的。 我目前在转接卡后只接了一块2T硬盘，硬盘接在转接卡转出的sata-1位。 引导参数默认的情况下，显示硬盘10。 把硬盘插在sata-2位，显示硬盘11； 把硬盘插在sata-4位，无法进系统，提示是未检测到硬盘。 想不明白，我的虚拟机设置下，系统认为到底有几个sata控制器？ DiskIdxMap= SataPortMap= SasIdxMap=0 要如何设置呢？ 请大佬可以指点一下，我目前仍在测试，测试结果随时更新。 ## 最后的总结在22楼 https://www.openos.org/threads/pve7-0satadsm7-0-1.3644/page-3#post-38098
为了搞清楚虚拟机下dsm系统的sata控制器情况，我启用ssh，lspci -v 命令查看。结果如下： root@DSM:~# lspci -v 0000:00:00.0 Class 0600: Device 8086:29c0 Subsystem: Device 1af4:1100 Flags: bus master, fast devsel, latency 0 0000:00:01.0

然后跟unraid的pci设备列表对比 Kernel driver in use: ahci 的只有2个设备？ 是否意味着，虚拟机下只有2个sata控制器？ 其中Device 197b:0585是我直通的m2转接卡，Device 8086:2922 不明。 但是为何第一个硬盘是从硬盘10开始排序呢？
這個試試 DiskIdxMap=0C00 SataPortMap=95 SasIdxMap=0 應該是不對~ 因為你敘述的sata-4 會變成找不到硬碟~ 這個有點奇怪 我要先知道這個指令加進去後順序變成甚麼樣子
