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 -ecommand. 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
