Rules

• Never pull a SATA drive out of a running array - shut the server down first. Hot-Swap SATA is a myth.
• Always back up a degraded array before screwing with it. Be afraid.
• Never buy Adaptec RAID controllers - especially SATA/SAS
• Never trust the output of arcconf - carefully reboot the server and verify using the BIOS.

Adaptec CLI Tools

These commands download and extract the 'arcconf' tool:

wget ftp://ftp.supermicro.com/CDR-LPZCR1_1.11_for_AOC-LPZCR1_AOC-SOZCR1/ASM/ASM4859/linux/StorMan-4.11.i386.rpm
rpm2cpio StorMan-4.11.i386.rpm | cpio -ivmur '*arcconf'


Name it “/usr/sbin/arcconf”.

chmod +x /usr/sbin/arcconf
arcconf getstatus 1
arcconf getconfig 1

Monitoring Script

#!/bin/bash
# raidmon.sh
#
# The intent of this script is to be run frequently from cron to alert a
# sysadmin to RAID problems with Adaptec controllers

# Who to send alerts to
ALERT=“gcooper@sonoracomm.com”

# Where is the arcconf utility
ARCCONF=“/usr/sbin/arcconf”

# note: this only tests the first array even if there is more than one
RAIDSTATUS=`$ARCCONF getconfig 1 | awk '/Status of logical device/ {print $6; exit}'`

if [ “$RAIDSTATUS” != “Optimal” ]
then
$ARCCONF getstatus 1 | mail -s “RAID Problem Report for ${HOSTNAME}” “$ALERT”
fi

exit 0

Monitor with cron

Add to /etc/crontab:

# check for RAID array problems every 10 minutes and send out a message
*/10 * * * * root /root/raidmon.sh 2>&1

SME Server

mkdir -p /etc/e-smith/templates-custom/etc/crontab
vi /etc/e-smith/templates-custom/etc/crontab/40raidmon

(modify per above)

expand-template /etc/crontab
cat /etc/crontab
