必需加入遠端Monitor機制才能提早發現硬碟問題，在作了些功課後決定使用SNMP(sample network manager protocol)。
Drive部份直到CentOS6.3都還有內建aacraid的module。
Download appliance部份 http://ftp.dell.com/scsi-raid/afa-apps-snmp.2807420-a04.tar.gz
Download ucd-snmp source code http://nchc.dl.sourceforge.net/project/net-snmp/ucd-snmp/4.2.7.1/ucd-snmp-4.2.7.1.tar.gz
準備compiler "ucd-snmp-4.x.x" source code:
tar vxzf ucd-snmp-4.2.7.1.tar.gz
cd ucd-snmp-4.2.7
$ ./configure --enable-reentrant --with-mib-modules=agentx
$make
$make install
編寫 snmpd.conf
vi /usr/local/share/snmp/snmpd.conf and add below two lines:
master agentx
pass .1.3.6.1.4.1.795 /usr/sbin/afasnmpd
準備安裝AAR-2410SA monitor tool:
tar vxzf afa-apps-snmp.2807420-a04.tar.gz
rpm -ihv afaapps-4.1-0.i386.rpm
rpm -ihv afasnmp-4.0-0.i386.rpm
vi /usr/local/share/snmp/afasnmpd.conf
trapcommunity "public"
trapsink localhost
trapsink [HOSTNAME]
CentOS系統本身不會自動產生/dev/afa0 檔，而這個檔是afacli cli必需存取的介面，可以透過以下步驟達成自動產生/dev/afa0:
cp MAKEDEV.afa /sbin/
vi /sbin/MAKEDEV.afa # make sure MAKEDEV.afa cd's /dev
加入udev 設定檔
vi /etc/udev/rules.d/99-local.rules
BUS=="pci", DRIVERS=="aacraid", PROGRAM="/sbin/MAKEDEV.afa afa0"
修改開機引導程式:
vi /etc/init.d/afasnmpd, 加入藍色部份:
....
case "$1" in
start)
echo -n "Starting snmpd: "
/usr/local/sbin/snmpd
sleep 2
echo -n "Starting afasnmpd: "
daemon /usr/sbin/afasnmpd
RETVAL=$?
[ $RETVAL -eq 0 ] && touch /var/lock/subsys/afasnmpd
echo
;;
stop)
echo -n "Shutting down afasnmpd: "
killproc afasnmpd
RETVAL=$?
[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/afasnmpd
echo
echo -n "Shutting down snmpd: "
killproc snmpd
;;
....
收尾:
/sbin/chkconfig --add afasnmpd
/sbin/chkconfig --level 35 afasnmpd on
