Send email alerts if Adaptec raid fails in Linux

Filed under: linux — Tags: , , , , — admin @ 10:56 am

For Adaptec Raid you need arcconf tool to check the raid status, you can install it based on the instructions provided on this link (For Debian) :
After you have arcconf installed, create /usr/bin/raidcheck with following content and make it executable :

RESULT=$(arcconf GETCONFIG 1 | grep Status | grep -v "Not Installed" | grep -v Optimal)
if [ -n "$RESULT" ]; then
    wget -O /dev/null
    else echo "Raid is OK"

Note : In my script I have chosen to use a php script on another server to send the alert, this way I wont need to install a mail server on every server which I am monitoring. you can do the same or change the wget line to whatever you want.
Put the script in the cron to check the raid status every 12 hours :

0 */12 * * * /usr/bin/raidcheck

How to update Adaptec raid driver on Centos & RHEL5

Filed under: CentOS,General — Tags: , , , , , , , — admin @ 6:51 pm

Download the driver RPMs from adaptec website, as I have 5805z controller, I downloaded the drivers from here :

You will get a file like this :


unpack it :

tar zxvf aacraid_linux_rpms_v1.1.7-28700.tgz

to get :


install rpm :

rpm -ivh --force aacraid-1.1.7-28700.rpm

it will only extract the files to /opt/Adaptec/aacraid :

cd /opt/Adaptec/aacraid
mkdir mods
mv aacraid_prebuilt.tgz mods
cd mods
tar zxvf aacraid_prebuilt.tgz
rm *.tgz

now you have prebuilt module for different kernels, copy the appropriate kernel module to aacraid.ko path, a command like :

cp aacraid-2.6.18-238.el5xen-x86_64 /lib/modules/2.6.18-274.18.1.el5xen/kernel/drivers/scsi/aacraid/aacraid.ko

if you have locate package installed, you can easy find all aacraid.ko files :

locate aacraid.ko | xargs -n1 modinfo | grep vers

when it is complete, reboot the server.
