SEF sysevent Functionality

In addition to using the SEF log file, you can use the Solaris sysevent feature to

obtain tape drive SCSI log sense error counter pages 2 and 3 for media analysis. By

default, the SEF sysevent feature is enabled and set to poll once before unload. The

SEF sysevent behavior is controlled by defaults.conf and samset.

In the defaults.conf file, the sef parameter can be used to enable SEF sysevent

feature by equipment ordinal, or to specify the log sense polling frequency. For more

information, see the defaults.conf(4) manu page.

▼ To Create the SEF sysevent Handler

1. Create the /var/tmp/xx file similar to the following:

#!/bin/ksh

echo “$@” >> /var/tmp/xx.dat

exit 0

2. Make the /var/tmp/xx file executable:

# chmod a+rwx /var/tmp/xx

3. Add the SEF sysevent handler to the syseventd file by typing the following:

# syseventadm add -vSUNW -pSUNWsamfs -cDevice -sSEF

/var/tmp/xx \”\$VENDOR\” \”\$PRODUCT\” \”\$USN\” \”\$REV\” \

$TOD \$EQ_ORD \”\$NAME\” \$INQ_TYPE \”\$MEDIA_TYPE\” \”\$VSN\”

\$LABEL_TIME \$LP2_PC0 \$LP2_PC1 \$LP2_PC2 \$LP2_PC3 \$LP2_PC4

\$LP2_PC5 \$LP2_PC6 \$LP3_PC0 \$LP3_PC1 \$LP3_PC2 \$LP3_PC3 \

$LP3_PC4 \$LP3_PC5 \$LP3_PC6 \$WHERE \$sequence

# syseventadm restart

This command creates the

/etc/sysevent/config/SUNW,SUNWsamfs,Device,sysevent.conf file

containing the SEF sysevent handler /var/tmp/xx and loads the event handler

into the syseventd daemon.

Note – The syseventadm(1M) command is not supported by the Solaris 8

Operating System. You must manually create the

/etc/sysevent/config/SUNW,SUNWsamfs,Device,sysevent.conf file and

contents, then type pkill -HUP syseventd to restart the syseventd daemon.

4. To load the SEF sysevent handler, use the command pkill -HUP syseventd to

activate the /var/tmp/xx SEF sysevent handler.

For more information about SEF sysevent usage, see the sefsysevent(4) man

page.
