Configuring the Remote Notification Facility

The software can be configured to notify you when potential problems occur in its environment. The system sends notification messages to a management station of your choice. The Simple Network Management Protocol (SNMP) software within the software manages the exchange of information between network devices such as servers, automated libraries, and drives.

The Sun SAM Management Information Base (MIB) defines the types of problems, or events, that the Sun SAM software can detect. The software can detect errors in configuration, tapealert events, and other atypical system activity. For more information, see the /var/snmp/mib/SUN-SAM-MIB.mib file.

The following procedures describe how to enable and disable remote notification.

How to Enable Remote Notification

Before You Begin

Ensure that the management station is configured and known to be operating correctly.

1. Examine the /etc/hosts file contents to ensure that the management station to which notifications should be sent is defined.

   The following sample file defines a management station with a host name of mgmtconsole.

   999.9.9.9       localhost
   999.999.9.999   loggerhost      loghost
   999.999.9.998   mgmtconsole
   999.999.9.9     samserver

   • If the management station is defined, close the file.

   • If the management station is not defined, add a definition and save and close the file.

2. Open the /etc/opt/SUNWsamfs/scripts/sendtrap file and evaluate the TRAP_DESTINATION= 'hostname' directive.

   This line specifies that remote notification messages be sent to port 161 of the server upon which the Sun Storage Archive Manager software is installed.

   • If you want to change the host name or port, replace the TRAP_DESTINATION directive line with TRAP_DESTINATION="mgmt-console-name:port". Note the use of quotation marks (" ") rather than apostrophes (` ') in the new directive.

   • If you want to send remote notification messages to multiple hosts, specify the directive in the following format:

     TRAP_DESTINATION="mgmt-console-name:port [mgmt-console-name:port]"

     For example:

     TRAP_DESTINATION="localhost:161 doodle:163 mgmt_station:1162"

3. Evaluate the COMMUNITY="public" directive. This line acts as a password that prevents unauthorized viewing or use of SNMP trap messages.

   Do one of the following, depending on the community string value of your management station:

   • If your management station's community string is also set to public, you do not have to edit this value.

   • If your management station's community string is set to a value other than public, edit the directive to replace public with the value that is used in your management station.

4. Save your changes to /etc/opt/SUNWsamfs/scripts/sendtrap and exit the file.

How to Disable Remote Notification

The remote notification facility is enabled by default. If you want to disable remote notification, perform this procedure.

1. If the /etc/opt/SUNWsamfs/defaults.conf file does not exist, use the cp command to copy /opt/SUNWsamfs/examples/defaults.conf to /etc/opt/SUNWsamfs/defaults.conf.
2. In the /etc/opt/SUNWsamfs/defaults.conf file, find the line that specifies SNMP alerts.

   # alerts=on

3. Remove the # symbol and change on to off.

   After editing, the line is as follows:

   # alerts=off

4. Save your changes and exit the file.
5. Use the pkill command to send a SIGHUP signal to the sam-fsd daemon.

   # pkill -HUP sam-fsd

   This command restarts the sam-fsd daemon and enables the daemon to recognize the changes in the defaults.conf file.
