如何在Linux下检查Adaptec RAID阵列的运行状况。
如何查看阵列卡的状态？

在FreeBSD中， aac是Adaptec AdvancedRAID Controller驱动程序。

查看有关RAID设备的信息

执行以下命令：

# dmesg | grep -i RAID

输出示例：

aac0:  mem 0xe8000000-0xe81fffff irq 16 at device 0.0 on pci6
aacd0:  on aac0

# pciconf -l | grep -i aac

输出：

aac0@pci0:6:0:0:	class=0x010400 card=0x02d19005 chip=0x02859005 rev=0x09 hdr=0x00

FreeBSD arcconf

arcconf是Adaptec SCSI RAID系列RAID控制器的命令行界面，用于配置和管理连接的存储设备。
它可用于获取有关RAID配置的详细信息，包括RAID的运行状况。

在FreeBSD中安装arcconf

执行以下命令：

# portsnap fetch update
# cd /usr/ports/sysutils/arcconf
# make install clean && rehash

如何使用arcconf来查看Adaptec RAID阵列的状态？

获取控制器1的信息：

# /usr/local/sbin/arcconf getconfig 1

输出示例：
