# aacraid.4

`aacraid` — Adaptec Series 6/7/8 6G 和 12G SAS+SATA RAID 控制器驱动

## 名称

`aacraid`

## 概要

要将此驱动编译进内核，请在内核配置文件中加入以下行：

> device pci device aacraid 要编译调试代码： options AACRAID\_DEBUG=N

或者，要在引导时以模块形式加载该驱动，请在 loader.conf(5) 中加入以下行：

```sh
aacraid_load="YES"
```

## 描述

`aacraid` 驱动提供对 Adaptec by PMC RAID 控制器的支持，包括 Series 6/7/8 及后续系列。

RAID 容器通过 `aacraidp0` 总线处理。物理总线由 `aacraidp?` 设备表示（从 aacraidp1 开始）。这些设备启用 SCSI 直通接口，允许通过 CAM [scsi(4)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man4/scsi.4.md) 子系统使用连接到卡上的设备（如 CD-ROM）。请注意，并非所有卡都允许启用此接口。

**`/dev/aacraid?`** 设备节点提供对控制器管理接口的访问。每块已安装的卡对应一个节点。如果加载了 `aacraid_linux.ko` 和 `linux.ko` 模块，将启用管理设备的 Linux 兼容 ioctl(2) 接口，并允许基于 Linux 的管理应用程序控制该卡。

## 硬件

`aacraidp?` 驱动支持以下 Adaptec 6G 和 12G SAS/SATA RAID 控制器：

* Adaptec ASR-6405(T|E)
* Adaptec ASR-6445
* Adaptec ASR-6805(T|E|Q|TQ)
* Adaptec ASR-7085
* Adaptec ASR-7805(Q)
* Adaptec ASR-70165
* Adaptec ASR-71605(E|Q)
* Adaptec ASR-71685
* Adaptec ASR-72405
* Adaptec Series 8 cards

## 文件

**`/dev/aacraid?`** aacraid 管理接口

## 诊断

在编译时将 `AACRAID_DEBUG` 设置为 0 到 3 之间的数字将启用逐步详细的调试消息。

适配器可异步向驱动发送状态和告警消息。这些消息会打印在系统控制台上，并排队等待管理应用程序检索。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man4/aacraid.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
