Dell Drac 5 User Manual

							Advanced Configuration of the DRAC 571
 NOTE: The DRAC 5 default user name is root and the default password is 
calvin.
You can access the DRAC 5 Web-based interface through the DRAC 5 NIC 
by using a supported Web browser, or through Server Administrator or IT 
Assistant.
See Supported Web Browsers for a list of supported Web browsers.
To access the DRAC 5 remote access interface using Server Administrator, 
launch Server Administrator. From the system tree on the left pane of the 
Server Administrator home page, click System→ Main System Chassis→ 
Remote Access Controller. For more information, see your Server 
Administrator User’s Guide. 
Telnet Console Provides access through the DRAC 5 to the server RAC 
port and hardware management interfaces through the 
DRAC 5 NIC and provides support for serial and 
RACADM commands including powerdown, powerup, 
powercycle, and hardreset commands.
NOTE: Telnet is an unsecure protocol that transmits all 
data—including passwords—in plain text. When 
transmitting sensitive information, use the SSH interface. 
SSH Interface Provides the same capabilities as the telnet console 
using an encrypted transport layer for higher security.
IPMI Interface Provides access through the DRAC 5 to the remote 
system’s basic management features. The interface 
includes IPMI over LAN, IPMI over Serial, and Serial 
over LAN. See the Dell OpenManage Baseboard 
Management Controller User’s Guide for more 
information.  Table 4-15. DRAC 5 Interfaces (continued)

Configuring the Network and IPMI LAN Settings
 NOTE: You must have Configure DRAC 5 permission to perform the following steps.
 
NOTE: Most DHCP servers require a server to store a client identifier token in its 
reservations table. The client (DRAC 5, for example) must provide this token during 
DHCP negotiation. For RACs, the DRAC 5 supplies the client identifier option using a 
one-byte interface number (0) followed by a six-byte MAC address.
 
NOTE: If your managed system DRAC is configured in Shared or Shared with Failover 
mode and the DRAC is connected to a switch with Spanning Tree Protocol (STP) 
enabled, network clients will experience a 20-30 second delay in connectivity when 
the management station’s LOM link state changes during the STP convergence.

Using RACADM Remotely
 NOTE: Configure the IP address on your DRAC 5 before using the racadm remote 
capability. For more information about setting up your DRAC 5 and a list of related 
documents, see Basic Installation of the DRAC 5.
RACADM provides a remote capability option (-r) that allows you to connect 
to the managed system and execute racadm subcommands from a remote 
console or management station. To use the remote capability, you need a 
valid user name (
-u option) and password (-p option), and the DRAC 5 
IP address.
 NOTE: If the system from where you are accessing the remote system does not 
have a DRAC certificate in its default certificate store, a message is displayed when 
you type a racadm command. 
Security Alert: Certificate is invalid - Name on 
Certificate is invalid or does not match site name
Continuing execution. Use –s option for racadm to 
stop the execution on certificate-related errors.

NOTE: Changes to the NIC IP address settings will close all user 
sessions and require users to reconnect to the DRAC 5 Web-
based interface using the updated IP address settings. All other 
changes will require the NIC to be reset, which may cause a brief 
loss in connectivity. 
						

							76Advanced Configuration of the DRAC 5
racadm continues to execute the command. However, if you use the –s 
option, racadm stops executing the command and displays the following 
message:
Security Alert: Certificate is invalid - Name on 
Certificate is invalid or does not match site name
Racadm not continuing execution of the command.
EORROR: Unable to connect to RAC at specified 
IP address
 NOTE: The racadm remote capability is supported only on management stations. 
For more information, see the Dell Systems Software Support Matrix on the Dell 
Support website at support.dell.com for more information.
 
NOTE: When using the racadm remote capability, you must have write permissions 
on the folders where you are using the racadm subcommands involving file 
operations, for example:
racadm getconfig -f 
or
racadm sslcertupload -t 1 -f c:\cert\cert.txt 
subcommands
RACADM Synopsis
racadm -r  -u  -p  
 
racadm -i -r   
For example:
racadm -r 192.168.0.120 -u root -p calvin getsysinfo
racadm -i -r 192.168.0.120 getsysinfo
If the HTTPS port number of the RAC has been changed to a custom port 
other than the default port (443), the following syntax must be used:
racadm -r 
: -u  -p 
  
racadm -i -r :

							80Advanced Configuration of the DRAC 5
You may encounter one or more of the following errors when using the 
racadm commands and subcommands:
 Local racadm error messages — Problems such as syntax, typographical 
errors, and incorrect names.
 Remote racadm error messages—Problems such as incorrect IP Address, 
incorrect username, or incorrect password.
When I ping the DRAC IP address from my system and then switch my 
DRAC 5 card between Dedicated and Shared modes during the ping 
response, I do not receive a response. 
Clear the ARP table on your system.
Configuring Multiple DRAC 5 Cards
Using RACADM, you can configure one or more DRAC 5 cards with 
identical properties. When you query a specific DRAC 5 card using its group 
ID and object ID, RACADM creates the racadm.cfg configuration file from 
the retrieved information. By exporting the file to one or more DRAC 5 cards, 
you can configure your controllers with identical properties in a minimal 
amount of time. 
 NOTE: Some configuration files contain unique DRAC 5 information (such as the 
static IP address) that must be modified before you export the file to other DRAC 5 
cards.
To configure multiple DRAC 5 cards, perform the following procedures:
1
Use RACADM to query the target DRAC 5 that contains the appropriate 
configuration. 
 NOTE: The generated .cfg file does not contain user passwords.
Open a command prompt and type:
racadm getconfig -f myfile.cfg
 NOTE: Redirecting the RAC configuration to a file using getconfig -f is only 
supported with the local and remote RACADM interfaces.
2Modify the configuration file using a simple text editor (optional).
