- Firstly install gsmartcontrol (Using apt-get or yum depending on OS)
yum -y install gsmartcontrol
- Now, enable SMART on each of your disks (This may be done already but better safe than sorry)
Eg:
smartctl --smart=on /dev/sda
- Now, copy the below script and make it executable:
#!/bin/bash # Only handle always updated values, add device path and vendor/model if which smartctl > /dev/null 2>&1 ; then # # if the 3ware-utility is found # get the serials for all disks on the controller # if which tw_cli > /dev/null 2>&1 ; then # support for only one controller at the moment TWAC=$(tw_cli show | awk 'NR < 4 { next } { print $1 }' | head -n 1) # - add a trailing zero to handle case of unused slot # trailing zeros are part of the device links in /dev/disk/by-id/... anyway # - only the last 9 chars seem to be relevant # (hopefully all this doesn't change with new kernels...) eval `tw_cli /$TWAC show drivestatus | grep -E '^p[0-9]' | awk '{print $1 " " $7 "0"}' | while read twaminor serial ; do twaminor=${twaminor#p} serial=${serial:(-9)} serial=AMCC_${serial}00000000000 echo "$serial=$twaminor" done` fi echo '<<<smart>>>' SEEN= for D in /dev/disk/by-id/{scsi,ata}-*; do [ "$D" != "${D%scsi-\*}" ] && continue [ "$D" != "${D%ata-\*}" ] && continue [ "$D" != "${D%-part*}" ] && continue N=$(readlink $D) N=${N##*/} if [ -r /sys/block/$N/device/vendor ]; then VEND=$(tr -d ' ' < /sys/block/$N/device/vendor) else # 2012-01-25 Stefan Kaerst CDJ - in case $N does not exist VEND=ATA fi if [ -r /sys/block/$N/device/model ]; then MODEL=$(sed -e 's/ /_/g' -e 's/_*$//g' < /sys/block/$N/device/model) else MODEL=$(smartctl -a $D | grep -i "device model" | sed -e "s/.*:[ ]*//g" -e "s/\ /_/g") fi # Excluded disk models for SAN arrays or certain RAID luns that are also not usable.. if [ "$MODEL" = "iSCSI_Disk" ] || ["$MODEL" = "LOGICAL_VOLUME" ]; then continue fi # Avoid duplicate entries for same device if [ "${SEEN//.$N./}" != "$SEEN" ] ; then continue fi SEEN="$SEEN.$N." # strip device name for final output DNAME=${D#/dev/disk/by-id/scsi-} DNAME=${DNAME#/dev/disk/by-id/ata-} # 2012-01-25 Stefan Kaerst CDJ - special option in case vendor is AMCC CMD= if [ "$VEND" == "AMCC" -a -n "$TWAC" ]; then DNAME=${DNAME#1} [ -z "${!DNAME}" ] && continue CMD="smartctl -d 3ware,${!DNAME} -v 9,raw48 -A /dev/twa0" # create nice device name including model MODEL=$(tw_cli /$TWAC/p${!DNAME} show model | head -n 1 | awk -F= '{ print $2 }') MODEL=${MODEL## } MODEL=${MODEL// /-} DNAME=${DNAME#AMCC_} DNAME="AMCC_${MODEL}_${DNAME%000000000000}" elif [ "$VEND" != "ATA" ] ; then TEMP= # create temperature output as expected by checks/smart # this is a hack, TODO: change checks/smart to support SCSI-disks eval `smartctl -d scsi -i -A $D | while read a b c d e ; do [ "$a" == Serial ] && echo SN=$c [ "$a" == Current -a "$b" == Drive -a "$c" == Temperature: ] && echo TEMP=$d done` [ -n "$TEMP" ] && CMD="echo 194 Temperature_Celsius 0x0000 000 000 000 Old_age Always - $TEMP (0 0 0 0)" DNAME="${VEND}_${MODEL}_${SN}" else CMD="smartctl -d ata -v 9,raw48 -A $D" fi [ -n "$CMD" ] && $CMD | grep Always | egrep -v '^190(.*)Temperature(.*)' | sed "s|^|$DNAME $VEND $MODEL |" done 2>/dev/null fi
- Re-inventory the server from Check_MK and it will pick up the SMART checks from your disks
