You can use arcconf to check the status of your Adaptec hardware RAID array. Below are the commands to download and install the program into a directory called /incero, and then the command to run the program. Tested with CentOS 5.5 64bit and CentOS 5.6 64bit.
tar -zxf asm_linux_x64_v6_50_18579.tgz
rm -f asm_linux_x64_v6_50_18579.tgz
chmod +x arcconf
yum -y install compat-libstdc++-33
./arcconf getconfig 1 AL
If you wish for your server to email you if an array becomes sub optimal you can use a script like the one posted by “quad3datwork” here: http://www.sysadmintalk.net/forums/Thread-CentOS-Adaptec-RAID-2405-arcconf-monitoring
Incero clients with our management services need not worry about RAID health, as it is constantly monitored 24/7 along with load and other server health parameters by our staff.
