Starting the KVM Console


This chapter includes the following sections:

KVM Console

The KVM console is an interface accessible from the
Cisco UCS Manager GUI
or the KVM Launch Manager that emulates a direct KVM connection. Unlike the KVM dongle, which requires you to be physically connected to the server, the KVM console allows you to connect to the server from a remote location across the network.

You must ensure that either the server or the service profile associated with the server is configured with a CIMC IP address if you want to use the KVM console to access the server. The KVM console uses the CIMC IP address assigned to a server or a service profile to identify and connect with the correct server in a
Cisco UCS.

Instead of using CD/DVD or floppy drives directly connected to the server, the KVM console uses virtual media, which are actual disk drives or disk image files that are mapped to virtual CD/DVD or floppy drives. You can map any of the following to virtual drives:

  • CD/DVD or floppy drives on your computer

  • Disk image files on your computer

  • CD/DVD or floppy drives on the network

  • Disk image files on the network

Recommendations for Using the KVM Console to Install a Server OS

To install an OS from a virtual CD/DVD or floppy drive, you must ensure that the virtual CD/DVD or floppy drive is set as the first boot device in the service profile.

Installing an OS using the KVM console may be slower than using the KVM dongle because the installation files must be downloaded across the network to the server. If you map a disk drive or disk image file from a network share to a virtual drive, the installation may be even slower because the installation files must be downloaded from the network to the KVM console (your computer) and then from the KVM console to the server. When using this installation method, we recommend that you have the installation media as close as possible to the system with the KVM console.

Virtual KVM Console

The KVM console is an interface accessible from CIMC that emulates a direct keyboard, video, and mouse (KVM) connection to the server. It allows you to connect to and control the server from a remote location, and to map physical locations to virtual drives that can by accessed by the server during this KVM session.

Important:

The KVM console requires JRE (Java Runtime Environment) version 1.5.0 or higher.

KVM
Tab

This tab provides command line access to the server. The menu options available in this tab are described below.

VM
Tab

Instead of using CD/DVD or floppy drives physically connected to the server, the KVM console uses virtual media, which are actual disk drives or disk image files that are mapped to virtual CD/DVD or floppy drives on the server. The
Client View
table displays the floppy images, floppy drives, CD/DVD drives, and ISO images that are available to the server.



Note


In order to use virtual media, the
Enabled
check box must be checked on the
Virtual Media
tab.


Name Description

Mapped
column

If the check box in this column is checked, the associated disk drive or image file can be accessed by the server. Clear the check box to disconnect the server from the drive or image file.

Each drive or image file can exist either on the users local computer or on the network, and each falls into one of three categories:

  • Virtual CD/DVD

  • Removable Media

  • Floppy—This category includes USB keys or flash drives.

You can enable Virtual Media for one drive or image in each of the three categories, but you cannot virtualize multiple drives or images in the same category.

Read Only
column

If checked, the server cannot write to the Virtual Media device even if the device has write capability.

Drive
column

Displays the path to the device used by the server.

Exit
button

Returns to the
KVM
tab.

Create Image
button

Opens the
Open
dialog box that lets you navigate to the local folder that you want to map on the server.

After the system has created the image, it saves the IMG file on your desktop and adds it to the
Client View
table. Check the check box in the
Mapped
column to complete the mapping process.

Add Image
button

Opens the
Open
dialog box that lets you navigate to the ISO or IMG file you want to the server to access.

After you select the file, the system adds it to the
Client View
table. Check the check box in the
Mapped
column to complete the mapping process.

Remove Image
button

Removes the selected image from the
Client View
table.

Details
button

Toggles the display of the
Details
area. This area contains a table showing the three device categories, their mapped status, read and write statistics, and the length of time that the device has been mapped.

USB Reset
button

Resets all USB devices connected to the server.

Note

The
Details
area must be visible in order to use this button.

  • Whether all keystrokes are passed to the target system when the console is in Windowed mode. The default is no.

  • The termination key when in single cursor mode. The default is
    F12.

  • The mouse acceleration to use on the target system. The default is
    Windows.

Single Cursor

Turns on the single cursor feature, which offsets mouse alignment issues encountered on some remote operating systems. When you turn this feature on, the mouse pointer is trapped within the viewer window.

To turn the feature off, press the termination key specified in the
Session Options
dialog box.

Stats

Opens the
Stats
dialog box, which displays the:

  • Frame rate measured in number of frames per second

Starting the KVM Console from the KVM Launch Manager

The KVM Launch Manager enables you to access a server through the KVM console without logging in to
Cisco UCS Manager.

Before You Begin

To access the KVM console for a server through the KVM Launch Manager, you need the following:

  • Cisco UCS
    username and password.

  • Name of the
    service profile
    associated with the server for which you want KVM access.

Procedure


Step 1
In your web browser, type or select the web link for
Cisco UCS Manager GUI.

Example:

The default web link is
http://UCSManager_IP

or
https://UCSManager_IP
. In a standalone configuration,

UCSManager_IP

is the IP address for the management port on the fabric interconnect. In a cluster configuration,

UCSManager_IP

is the IP address assigned to
Cisco UCS Manager.

Step 2
On the
Cisco UCS Manager
page, click
KVM Launch Manager.
Step 3
On the
UCS – KVM Launch Manager Login
page, do the following:


  1. Enter your
    Cisco UCS
    username and password.

  2. Click
    OK.
Step 4
In the
Service Profiles
table of the KVM Launch Manager, do the following:


  1. Choose the
    service profile
    for which you need KVM access to the associated server.

  2. In the
    Launch KVM
    row for that
    service profile, click
    Launch.

    The KVM console opens in a separate window.

    Tip

    If the Caps Lock key on your keyboard is on when you open a KVM session, and you subsequently turn off your Caps Lock key, the KVM console may continue to act as if Caps Lock is turned on. To synchronize the KVM console and your keyboard, press
    Caps Lock
    once without the KVM console in focus and then press
    Caps Lock
    again with the KVM console in focus.
