===== 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:

<file>
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'
</file>

Name it ''/usr/sbin/arcconf''.

<file>
chmod +x /usr/sbin/arcconf
arcconf getstatus 1
arcconf getconfig 1
</file>

===== Monitoring Script =====

<file>
#!/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="you@yourdomain.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
</file>

===== Monitor with cron =====

Add to ''/etc/crontab'':

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

==== SME Server ====

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

Modify per above, then:

<file>
expand-template /etc/crontab
cat /etc/crontab
</file>
