2.1 Introduction

Virtual media

is a mechanism available only for systems with an

iLO

-based management processor.

Virtual media allows a system to boot an ISO image over the network; it is the alternate boot
mechanism to

PXE

.

When you perform an Insight Control for Linux operation (such as, a

bare-metal

discovery, a

capture of a Linux OS image, a deployment of an image, or install an operating system) on a
server that has been configured to use virtual media, a bootable ISO image file is created in the
/opt/repository/iso

directory on the

CMS

. The bootable ISO image file will contain the

previously configured network parameters and will be used to configure the boot NIC on the
target server. When the server is booted, the iLO is instructed to mount the bootable ISO from
the CMS using

HTTPS

port 60002 by default. After the iLO mounts the bootable ISO file, the

server’s bootable NIC is configured and all subsequent network activity, (for example, an OS
installation) is performed through the boot NIC. If the server’s NIC has been configured to PXE
boot, it is possible that, even though the server failed to boot using virtual media, it may still
boot using PXE, depending on your

DHCP

server configuration.

IMPORTANT:

When using Virtual media, the server's iLO connects to port 60002 (HTTPS) on

the CMS to obtain the ISO image. That port must be opened on the CMS or the server will not
boot as expected and the task will not complete successfully.

If the HTTPS port on the CMS is closed, the server will not boot as expected.

You can specify an alternate port by editing the /opt/mx/icle/icle.properties file
to set the following parameter:

REPOSITORY_HTTPS_PORT=port-number

Where port-number is the number of the alternate port.

If port 60002 (HTTPS) on the CMS (or an alternate port that you specified) is closed and if
DHCP is configured in your environment, the server can fail to boot using virtual media
and boot using PXE boot instead.

Virtual media requires some initial preparation, which is described in

“Preparing for virtual

media” (page 26)

Using virtual media requires that you predefine network configuration parameters so that they
are incorporated into the ISO image. HP Insight Control for Linux provides two tools, Define
Networks

and the Network Configuration Editor, to enable you to specify the network

configuration parameters for servers that will not be PXE-booted.
