HP XC System Software Installation Guide Version 4.0

9. Repeat steps 5 and 6 and make the same changes to the sendmail.cf file.
10. Save the changes to the file and exit the text editor.
11. Restart sendmail:
# service sendmail restart
To forward mail to users, the sendmail service requires users to create .forward files in their
home directories to specify where mail is to be sent.
If you intend to make additional, more advanced modifications to sendmail, HP recommends
that you do not modify the .cf files directly. Rather, modify the .mc files and run them through
an M4 processor to create the .cf files. The M4 processing tools are part of the sendmail-cf
RPM, which is not installed by default. The sendmail-cf RPM is available on the HP XC
distribution DVD in the extra RPMs directory.
Consult any third-party Linux system administration reference manual if you need more
information about configuring sendmail.
To use a mail program other than sendmail, set the LSB_MAILPROG variable in the /opt/
hptc/lsf/top/conf/lsf.conf file to the appropriate mail program after the system
configuration is complete.
5.4 Customizing the Nagios Environment (Required)
Nagios is a highly customizeable system monitoring tool that you can tailor to specific installation
and monitoring requirements. HP recommends that you consider certain aspects of the Nagios
environment as part of the initial system setup to optimize the type of system events reported
to you as well as the frequency of alerts.
Consider the following items when customizing Nagios to suit your environment:
• Setting thresholds for load averages
• Setting up e-mail contacts
• Modifying alert rules files
• Setting up event logging
• Using event handler scripts to remove suspect nodes from the SLURM lsf partition
Because customizing and tuning the Nagios environment can be done at any time and as often
as required, the procedures are documented in the HP XC System Software Administration Guide.
See that document and return here when you have completed tuning the Nagios environment.
5.5 Configuring Access to the Console Port on the Head Node (Required)
Perform this task only if the console port on the head node is connected to the external network.
Otherwise, omit this task.
To monitor sensor data and system event logs, Nagios requires that the console port on the head
node be accessible. The procedure is documented in the HP XC System Software Administration
Guide. Return here when you have completed the task.
5.6 Setting the BMC Password on HP Integrity Systems (Required)
To monitor sensor data and system event logs, Nagios requires that you set a base motherboard
controller (BMC) password on HP Integrity systems. This procedure is documented in the HP
XC System Software Administration Guide. Return here when you have completed the task.
5.7 Installing Additional HP Software Products (Optional)
This task is optional. Perform this task only if you need to install additional HP software products.
Otherwise, omit this task.
