NOTE:

To discover or identify a server that will become a managed system, HP SIM requires
that a SNMP read community string must be set to public in the global credentials
for that server. There may be additional read community string settings in addition to
public

, but public must be specified.

Select Send traps to refer to this instance of HP SIM.

You can optionally set Send a sample SNMP trap to this instance of HP SIM, but it
is not required.

6.

Make the following settings to configure SSH:

Select Configure secure shell (SSH) access authentication.

Select Host based authentication.

7.

Unselect all the other sections on this screen unless your environment uses those particular
protocols or features.

8.

Select Next and the Enter Credentials screen appears.

9.

Select the Use the following credentials for all systems radio button and supply the
managed system credentials, which is typically the root user name and password.

10. Select Run Now.

Selecting a protocol that is not supported in your environment causes an error and a task will
report its status as failed. Even if this happens, it is possible that the SNMP and SSH settings
required for Insight Control for Linux were configured correctly. Look at the task results to verify
this.

This task must complete successfully before you can continue.

4.4.5 Configuring console access and logging

This task is optional. However, serial console access and logging are not available until you
complete this task.

When you configure the monitoring features of Insight Control for Linux on the CMS, one of the
features that is automatically configured is the Console Management Facility (

CMF

). CMF

captures, logs, monitors, and enables you to connect directly to the serial console on each of your
Insight Control for Linux managed systems directly from the CMS. This is a very helpful
management and debugging tool because many system errors and alerts are output only to the
system's console. With CMF, all serial console activity is logged on the CMS. Thus, if a problem
occurs, you can go back through the logs to help determine what events occurred and when the
events occurred. For more information on CMF, see

Chapter 18 (page 193)

.

Configuring Managed Systems for Console Monitoring

NOTE:

For information on how to update a RHEL Kickstart file or a SLES AutoYaST file to

configure the operating system to redirect its output to its serial port, see

Section 7.2.4 (page 86)

.

Each system BIOS provides two serial ports to the OS: COM1, which appears to the Linux OS as
ttyS0

, and COM2 which appears as ttyS1. Sometimes there are more than two ports, but

ignore these extra ports.

The ROM Based Setup Utility, which can be accessed from the console at system power up, has
settings for the embedded serial port and the virtual serial port. For each of these ports, you
choose which OS serial port it will be associated with.

For example, if the virtual serial port is assigned to COM1 in the BIOS, the OS must be configured
to use ttyS0 as its system console. If the virtual serial port is associated with COM2, the OS
must use ttyS1 as its console.
