I‘ve Adaptec RAID 1 set via 5405 PCI card. I know how to get check the health of Adaptec RAID array under Linux, but how do I find information about my RAID card, RAID status, disk failure and other information via command line?

aac is Adaptec AdvancedRAID Controller driver under FreeBSD operating system that works with HP NetRAID, IBM ServeRAID, Sun STK RAID, Dell PERC / CERC, and Adaptec SCSI / SATA systems. The Adaptec AAC family of SCSI Ultra2, Ultra160, and Ultra320, SATA and SAS RAID controllers.

Find Out Information About Your RAID Device

Type the following commands:
# dmesg | grep -i RAID
Sample Outputs:

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

# pciconf -l | grep -i aac
Output:

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

FreeBSD arcconf

arcconf is command Line Interface for the Adaptec SCSI RAID family of RAID controllers, used to configure and manage connected storage devices. It can be used to get detailed information about RAID configuration including health status.

FreeBSD Install arcconf

Type the following commands:
# portsnap fetch update
# cd /usr/ports/sysutils/arcconf
# make install clean && rehash

How Do I Use arcconf To Information About The Health Of My Adaptec RAID Array?

Type the following command at a shell prompt to get the information controller # 1:
# /usr/local/sbin/arcconf getconfig 1
Sample Outputs:
