ServerView Remote Management Frontend
1 Preface
The ServerView Remote Management Frontend provides you with a web-based working environment for the remote management of PRIMERGY servers which is integrated in the ServerView Operations Manager. The ServerView Remote
Management Frontend is started from the ServerView Operations Manager and the installation of this application is therefore a necessary precondition.
The ServerView Remote Management Frontend and the ServerView Operations Manager are referred to below as the Remote Management Frontend and the Operations Manager respectively.
You simply need a standard web browser for the display at the remote workstation. You can open a separate browser window for each PRIMERGY server displayed in the Operations Manager ServerList window. From here, you can then open various windows for the remote management of the corresponding PRIMERGY server.
As a web-based solution, the Remote Management Frontend can be installed on a remote workstation set up under a Windows or Linux system.
I
In the case of an individual PRIMERGY server with installed iRMC/ iRMC S2, you can also use the Remote Management Frontend functionality via this iRMC/ iRMC S2's web interface (See the manuals
“iRMC - integrated Remote Management Controller” and “iRMC S2 - integrated Remote Management Controller”).
ServerView Remote Management Frontend 5
Overview Preface
1.1
Overview
The type of window displayed in the Remote Management Frontend depends, on the one hand, on the hardware (iRMC, RSB etc.) which you use to establish the connection to the managed server and, on the other, on the interface which is provided in each case.
Hardware-specific displays in the Remote Management Frontend
The Remote Management Frontend's displays and controls are adapted to the remote hardware via which you establish the connection to a managed
PRIMERGY server:
– In the case of a PRIMERGY server with an installed iRMC or iRMC S2, you can use either the Telnet/SSH “Remote Manager” application or the managed server's power management and console redirection window in the Remote Management Frontend's console area.
– In the case of a PRIMERGY server with an installed RSB or RSB S2/
RSB S2 LP (as of firmware version 6.4.57.29), the Telnet “Remote
Manager” application is available to you in the Remote Management
Frontend's console area once a connection has been established.
Only in the case of RSB:
You can use the Remote Manager to redirect the display at the console of the managed server. In this way, you can access the BIOS setup and the
RemoteView/Diagnose system tools on the managed server.
– In the case of a PRIMERGY server with an installed BMC with firmware version 2.x or higher, the managed server's power management and console redirection window is available in the Remote Management
Frontend's console area after the establishment of a connection.
– In the case of a blade server with a RemoteView Management Blade, the
RemoteView Management Blade Telnet “Console Menu” application is available to you in the Remote Management Frontend's console area after the establishment of a connection. You can use the Console Menu to redirect the display at the consoles of the managed server blades. In this way, you can access the BIOS setup at the managed server blade.

I
The Remote Management Frontend is not listed in the Start menu.
I
In the case of a PRIMERGY server with installed iRMC/ iRMC S2, you can also call the Remote Management Frontend functionality for this server via the corresponding links in the iRMC/ iRMC S2's web interface
(see the manuals “iRMC - integrated Remote Management Controller” and “iRMC S2 - integrated Remote Management Controller”).
ServerView Remote Management Frontend 15
Requirements Starting the Remote Management Frontend
3.1
Requirements
Before you can start the Remote Management Frontend and establish a connection to the managed server, a number of requirements must fulfilled both at the managed server and at the remote workstation.
3.1.1
Requirements at the managed server
Depending on whether the Remote Management Frontend accesses the managed server via an iRMC/ iRMC S2, an RSB/ RSB S2/ RSB S2 LP, a BMC or a RemoteView Management Blade, the following requirements must be fulfilled at the managed server:
– iRMC/ iRMC S2
Both the iRMC/ iRMC S2's LAN interface and text console redirection (via
Serial Over LAN) must be configured.
I
Text console redirection via Serial over LAN (SOL) assumes that the operating system and/or the BIOS use serial port 1 (COM1) for text console redirection.
For detailed information, see the manuals “iRMC - integrated Remote
Management Controller” and “iRMC S2 - integrated Remote Management
Controller”.
– RSB S2/ RSB S2 LP (3HU)
Access via the Remote Management Frontend to an
RSB S2/ RSB S2 LP/ RSB S2 LP (3HU) is only possible if the
RSB S2/ RSB S2 LP/ RSB S2 LP (3HU) is operated with firmware version
*29 or higher.
16 ServerView Remote Management Frontend
Starting the Remote Management Frontend Requirements
The management port of the RSB S2/ RSB S2 LP (3HU) on the managed server should be configured to the default value 3172.
I
Since the Operations Manager does not know the management port value, the Remote Management Frontend works with the default value.
Since a connection is not automatically established when the Remote
Management Frontend is started, you can correct any nonstandard value for the management port after the Remote Management
Frontend has been started.
– BMC
The BMC must be configured for an IPMI-over-LAN connection and console redirection.
– RemoteView Management Blade
The management port of the RemoteView Management Blade on the managed server should be configured to the default value 3172.
I
Since the Operations Manager does not know the management port value, the Remote Management Frontend works with the default value.
Since a connection is not automatically established when the Remote
Management Frontend is started, you can correct any nonstandard value for the management port after the Remote Management
Frontend has been started.

4.2
Establishing a connection to the managed server
This section describes how you establish the connection to the managed server both in the Remote Management window for the Remote Manager and in the
Remote Management window for console redirection and power management.
4.2.1
Establishing a connection to the iRMC/ iRMC S2,
RSB S2/ RSB S2 LP (3 HU) via Telnet/SSH (Remote
Manager)
I
The Remote Management Frontend takes over the IP address of the iRMC/ iRMC S2, RSB/ RSB S2/ RSB S2 LP (3HU) / RemoteView
Management Blade from the Operations Manager.
The use of Remote Manager for the iRMC/ iRMC S2 is described in the manuals
“iRMC - integrated Remote Management Controller” and “iRMC S2 - integrated
Remote Management Controller”.
Requirements at a managed server with iRMC/ iRMC S2
Access via Telnet must be enabled for the iRMC/ iRMC S2 (see manuals “iRMC
- integrated Remote Management Controller” and “iRMC S2 - integrated
Remote Management Controller”).
I
Access via the Telnet protocol is deactivated by default for security reasons, as passwords are transmitted in plain text.
I
Maximum number of parallel Telnet/SSH sessions in the case of connection via an iRMC/ iRMC S2:
– Telnet: up to 4
– SSH: up to 2
– Telnet and SSH in total: up to 4
42 ServerView Remote Management Frontend
Working with the Remote Management Frontend Connection to server
Requirements at a managed server with RSB S2 /RSB S2 LP (3 HU)
– The framework vehicle of the RSB S2/ RSB S2 LP (3HU) must be 6.4.57.29 or higher.
– Access via Telnet must be activated via RSB S2/ RSB S2 LP (3HU).
I
Since the Operations Manager does not know the management port value, the Remote Management Frontend works with the default value.
Since a connection is not automatically established when the Remote
Management Frontend is started, you can correct any nonstandard value for the management port after the Remote Management
Frontend has been started.
I
Maximum number of parallel Telnet sessions for a connection via an RSB
S2/ RSB S2 LP (3 HU) (with firmware version 7.0 or higher): maximum 4

Connection to server Working with the Remote Management Frontend
Establishing a Telnet/SSH connection and logging into the Remote
Manager
I
The example below describes the establishment of Telnet/SSH connection to the managed PRIMERGY server via an iRMC/ iRMC S2.
The establishment of a Telnet connection to a PRIMERGY server via an
RSB/ RSB S2/ RSB S2 LP (3HU) is very similar.
Proceed as follows:
Ê In the Operations Manager Remote Management view, click the iRMC Telnet or iRMC SSH button:
44
Figure 14: Operations Manager: Remote Management view - starting Remote Manager
The Java applet for the Telnet or SSH connection is started and the Remote
Management window is displayed (here we use the example of an SSH connection, see
).
I
If the screen displays for SSH and Telnet connections differ only with respect to the connection-specific information displayed, the display for an SSH connection is shown below.
ServerView Remote Management Frontend
Working with the Remote Management Frontend Connection to server
Figure 15: Establishing an SSH connection to the iRMC/ iRMC S2
ServerView Remote Management Frontend 45
Connection to server Working with the Remote Management Frontend
Ê In the connection bar, click Connect .
I
If the connection attempt fails, then this may be due to the fact that the management port number at the managed machine is not 3172
(Telnet) or 22 (SSH).
The management port number is not known to the Operations
Manager and the Remote Management Frontend therefore uses the default value (3172 for Telnet connections or 22 for SSH connections).
As soon as the connection to the iRMC/ iRMC S2 has been established, you are requested to enter the user name and password.
– Logging into the Remote Manager over an SSH connection
I
If the host key of the managed server is not yet registered at the remote workstation, the SSH client issues a security alert with suggestions on how to proceed.
The following login window is displayed:
46
Figure 16: SSH connection: Logging in to the Remote Manager
Ê Enter your user name and password and confirm your entries by clicking Login .
The main menu of the Remote Manager is then displayed (see

4.2.2
Establishing a connection to the iRMC/ iRMC S2/BMC for power management and console redirection
I
The example below illustrates the establishment of a connection to an iRMC/ iRMC S2 which permits power management and console redirection for the managed server. A connection to a BMC is established in a very similar way.
Proceed as follows:
Ê In the Operation Manager Remote Management view, click the iRMC Power
Management button.
Figure 19: Operations Manager: Remote Management view -
Starting power management and console redirection
The Java applet for power management and console redirection is started and the Remote Management window is displayed (

Ê Click the Logon button to log in to the iRMC/ iRMC S2.
You are then prompted to enter your iRMC/ iRMC S2 user name and
password (see figure 21 on page 50 ):
Figure 21: Power management and text console redirection - Login window
Ê Enter your user name and password and click Login to confirm.

The connection to the iRMC/ iRMC S2 is established and the commands for the power management of the managed server can be activated (1).
However, the server console is still offline (2).
Ê Click Enter Console to start the console redirection session.
I
If you access the managed server via a Kalypso BMC, you will be asked (by the Kalypso BMC's Telnet server) to enter your user name and password again in order to start the console redirection session.
You are then connected to the console and can execute the required command, either by entering it directly in the console area or by clicking it in the Command drop-down list (IPMI commands only):
