7 Discovering systems, switches, and enclosures

This chapter addresses the following tasks, which you must complete in the following order when
you are configuring and setting up Insight Control for Linux:

1.

“Discovering systems” (page 71)

2.

“Assigning Insight Control for Linux licenses to discovered systems” (page 74)

3.

“Preparing and discovering switches and enclosures” (page 75)

4.

“Changing the boot method” (page 76)

7.1 Discovering systems

A server must first be discovered before HP SIM or Insight Control for Linux can manage and
monitor it. Discovery is the process of finding servers in the management domain so that they can
be managed from the

CMS

.

NOTE:

To discover or identify a server that becomes a

managed system

, HP SIM requires that

the SNMP read community string must be set to public in the global credentials for that server.
The value public is the default value. Use the Options

→Security→Credentials→Global Credentials

menu item to verify or set this parameter.

There may be additional read community string settings in addition to public, but public must
be specified. If you need to add another read community string, select Add to add another one,
but do not remove public.

The system discovery process depends on whether the server is installed with a supported Linux
OS (a running system) or not.

Use the appropriate procedure to discover systems:

“Discovering bare-metal servers using PXE” (page 71)

“Discovering bare-metal servers using virtual media” (page 72)

“Discovering running systems ” (page 73)

7.1.1 Discovering bare-metal servers using PXE

This section describes the discovery process for

bare-metal

servers.

NOTES:

You can update a server's firmware automatically as part of the bare-metal discovery process.
For information on enabling this feature, see

Section 12.2.3 (page 132)

.

You can initiate a one-time PXE boot, or set the server to always PXE boot before booting from
the local hard disk. Either method is acceptable.

For the servers to PXE boot the Insight Control for Linux

RAM disk

, you must have configured

DHCP

as described in the HP Insight Control for Linux Installation Guide. For a description of

the Insight Control for Linux RAM disk environment, see

Section 1.8 (page 18)

.

Powering on the server and initiating a PXE boot causes the server to boot the Insight Control
for Linux RAM disk, which automatically contacts the

CMS

, discovers the server and

management processor, and sets the user name and password on the management processor.
