IBM 2104 Model DU3 - Manual (Page 75)

Collecting Errors
Attention: The following procedure is for AIX operating systems only and does not
apply to Linux operating systems.
To enable the collection of 2104 disk enclosure errors, add this cron job SES
Healthcheck to the system cron table.
Note: Root permissions will be required to perform this update.
Edit the system crons with the crontab -e command. At the bottom of the file, enter:
15 * * * * /usr/lpp/diagnostics/bin/run_ses_healthcheck 1>/dev/null 2>/dev/null
For additional details of the crontab command, go to the following Web page:
http://publib16.boulder.ibm.com/pseries/en_US/cmds/aixcmds1/crontab.htm
This cron runs at 15 minutes after each hour, and sends mail to the
″root user″ with
details of any errors that are present in the enclosure. It also presents a console
message indicating which enclosure has a problem.
The cron requires a script. To create this script, generate a file named
run_ses_healthcheck in directory /usr/lpp/diagnostics/bin. The contents of the file
must be:
#!/bin/ksh
#Name: run_ses_healthcheck
#Location: /usr/lpp/diagnostics/bin
#Function: SCSI SES hourly healthcheck
for i in `lsdev -Cc container -t ses -s scsi -F name -S available`
do
diag -cd $i > /dev/null
if [ $? -ne 0 ]
then
/usr/lpp/diagnostics/bin/diagrpt -o > /tmp/ses.health.output
# you may want to process the output prior to placing it in
# a file.
# To notify the user of the error, a sample mail instruction is shown
# below.
mail -s ’2104 Health Check’ root < /tmp/ses.health.output
rm /tmp/ses.health.output
fi
done
Note: Although, because of page width, the final line of the contents is shown here
split between two lines, you must enter it all on one line.
Give the following command so that the script can be run:
chmod 544 /usr/lpp/diagnostics/bin/run_ses_healthcheck
