Managing Remote Presence

This chapter includes the following sections:

Configuring Serial Over LAN

Serial over LAN enables the input and output of the serial port of a managed system to be redirected over IP. Configure and use serial over LAN on your server when you want to reach the host console with Cisco IMC.


Important

You cannot use native serial redirection and serial over LAN simultaneously.


Before you begin

You must log in as a user with admin privileges to configure serial over LAN.

Procedure


Step 1

In the Navigation pane, click the Compute menu.

Step 2

In the Compute menu, select a server.

Step 3

In the work pane, click the Remote Management tab.

Step 4

In the Remote Presence pane, click the Serial over LAN tab.

Step 5

In the Serial over LAN Properties area, update the following properties:

Name Description

Enabled check box

If checked, Serial over LAN (SoL) is enabled on this server.

Baud Rate drop-down list

The baud rate the system uses for SoL communication. This can be one of the following:

  • 9600 bps

  • 19.2 kbps

  • 38.4 kbps

  • 57.6 kbps

  • 115.2 kbps

Com Port drop-down list

The serial port through which the system routes SoL communication.

Note 

This field is only available on some C-Series servers. If it is not available, the server always uses COM port 0 for SoL communication.

You can select one of the following:

  • com0—SoL communication is routed through COM port 0, an externally accessible serial port that supports either a physical RJ45 connection to an external device or a virtual SoL connection to a network device.

    If you select this option, the system enables SoL and disables the RJ45 connection, which means that the server can no longer support an external serial device.

  • com1—SoL communication is routed through COM port 1, an internal port accessible only through SoL.

    If you select this option, you can use SoL on COM port 1 and the physical RJ45 connection on COM port 0.

Note 

Changing the Com Port setting disconnects any existing SoL sessions.

Note 

This option is available only on some C-Series servers.

SSH Port filed

The port through which you can access Serial over LAN directly. The port enables you to by-pass the Cisco IMC shell to provide direct access to SoL.

The valid range is 1024 to 65535. The default value is 2400.

Note 

Changing the SSH Port setting disconnects any existing SSH sessions.

Step 6

Click Save Changes.


Configuring Virtual Media

Before you begin

You must log in as a user with admin privileges to configure virtual media.

Procedure


Step 1

In the Navigation pane, click the Compute tab.

Step 2

In the Compute tab, click the Remote Management tab.

Step 3

In the Remote Management tab, click the Virtual Media tab.

Step 4

In the Virtual Media Properties area, update the following properties:

Name Description

Enabled check box

If checked, virtual media is enabled.

Note 

If you clear this check box, all virtual media devices are automatically detached from the host.

Active Sessions field

The number of virtual media sessions that are currently running.

Enable Virtual Media Encryption check box

If checked, all virtual media communications are encrypted.

Low Power USB enabled check box

If checked, low power USB is enabled.

If the low power USB is enabled, after mapping the ISO and rebooting the host, the virtual drives appear on the boot selection menu.

But, while mapping an ISO to a server that has a UCS VIC P81E card and the NIC is in Cisco Card mode, this option must be disabled for the virtual drives to appear on the boot selection menu.

Step 5

Click Save Changes.


Creating a Cisco IMC Mapped vMedia Volume

Before you begin

You must log in with admin privileges to perform this task.

Procedure


Step 1

In the Navigation pane, click the Compute menu.

Step 2

In the Compute menu, select a server.

Step 3

In the work pane, click the Remote Management tab.

Step 6

In the Add New Mapping dialog box, update the following fields:

Name Description

Volume field

The identity of the image mounted for mapping.

Mount Type drop-down list

The type of mapping. This can be one of the following:

Note 

Ensure that the communication port of the mount type that you choose is enabled on the switch. For example, when you are using CIFS as your mount type, ensure port 445 (which is its communication port) is enabled on the switch. Similarly, enable ports 80 for HTTP, 443 for HTTPS and 2049 for NFS when you use them.

  • NFS—Network File System.

  • CIFS—Common Internet File System.

  • WWW(HTTP/HTTPS)—HTTP-based or HTTPS-based system.

    Note 

    Before mounting the virtual media, Cisco IMC tries to verify reachability to the end server by pinging the server.

Remote Share field

The URL of the image to be mapped. The format depends on the selected Mount Type:

  • NFS—Use serverip:/share.

  • CIFS—Use //serverip/share.

  • WWW(HTTP/HTTPS)—Use http[s]://serverip/share.

Remote File field

The name and location of the .iso or .img file in the remote share.

Mount Options field

Industry-standard mount options entered in a comma separated list. The options vary depending on the selected Mount Type.

If you are using NFS, leave the field blank or enter one or more of the following:

  • ro

  • rw

    Note 

    The folder, which is shared, should have write permissions to use read-write option. Read-write option is available only for .img files.

  • nolock

  • noexec

  • soft

  • port=VALUE

  • timeo=VALUE

  • retry=VALUE

If you are using CIFS, leave the field blank or enter one or more of the following:

  • soft

  • nounix

  • noserverino

  • guest

  • username=VALUE—ignored if guest is entered.

  • password=VALUE—ignored if guest is entered.

  • sec=VALUE

    The protocol to use for authentication when communicating with the remote server. Depending on the configuration of CIFS share, VALUE could be one of the following:

    • None—No authentication is used

    • Ntlm—NT LAN Manager (NTLM) security protocol. Use this option only with Windows 2008 R2 and Windows 2012 R2.

    • Ntlmi—NTLMi security protocol. Use this option only when you enable Digital Signing in the CIFS Windows server.

    • Ntlmssp—NT LAN Manager Security Support Provider (NTLMSSP) protocol. Use this option only with Windows 2008 R2 and Windows 2012 R2.

    • Ntlmsspi—NTLMSSPi protocol. Use this option only when you enable Digital Signing in the CIFS Windows server.

    • Ntlmv2—NTLMv2 security protocol. Use this option only with Samba Linux.

    • Ntlmv2i—NTLMv2i security protocol. Use this option only with Samba Linux.

If you are using WWW(HTTP/HTTPS), leave the field blank or enter the following:

  • noauto

    Note 

    Before mounting the virtual media, Cisco IMC tries to verify reachability to the end server by pinging the server.

  • username=VALUE

  • password=VALUE

User Name field

The username for the specified Mount Type, if required.

Password field

The password for the selected username, if required.

KVM Console

The KVM console is an interface accessible from Cisco IMC that emulates a direct keyboard, video, and mouse (KVM) connection to the server. The KVM console allows you to connect to the server from a remote location.

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. You can map any of the following to a virtual drive:

  • CD/DVD or floppy drive on your computer

  • Disk image files (ISO or IMG files) on your computer

  • USB flash drive on your computer

  • CD/DVD or floppy drive on the network

  • Disk image files (ISO or IMG files) on the network

  • USB flash drive on the network

You can use the KVM console to install an OS on the server.


Note

When launching the KVM Console from Internet Explorer 6 SP1 on Windows Server 2003, the browser will report that it cannot download a required file. If this occurs, click the browser Tools menu and select Internet Options. Click the Advanced tab and, in the Security section, uncheck the checkbox for "Do not save encrypted pages to disk." Launch the KVM Console again.
