If you’ve ever tried to reset the password on a Dell Remote Access Card III (DRAC3), then you probably already know that trying to manage a DRAC III in a Linux environment can be frustrating – especially since current (as of this writing) versions of Dell’s OpenManage Server Administration software (OMSA) aren’t backward compatible with older hardware like the Dell PowerEdge 2650. But with the right tools, you’ll be able to access your DRAC III and do things like reset the password, set up networking, update firmware, and more.
Some might try to convince you that the only way to reset the password and do other management tasks with your DRAC 3 is to install OMSA. That’s not entirely true. If you want to do a full install of OMSA, that’s fine. I’ve written a separate blog post to help you do just that. But if you don’t want the extra overhead of a full OMSA install, you can get away with using yum to install only the few packages that are required to manage the DRAC, including the command line tool racadm.
The most current version of the OMSA tools that will run on a Dell PowerEdge 2650 is OMSA 5.5, so that’s what we’ll use. Keep in mind that if you try to install a later version of OMSA, you’ll likely run into trouble.
Step 1: Set up the Dell OMSA Repository
wget -q -O - http://linux.dell.com/repo/hardware/2008_Q3/bootstrap.cgi | bash
============================================================================================================================ Package Arch Version Repository Size ============================================================================================================================ Installing: firmware-addon-dell i386 2.1.2-1.1 dell-omsa-indep 56 k Installing for dependencies: firmware-tools noarch 2.1.2-4.1 dell-omsa-specific 203 k libsmbios i386 2.1.0-1.2 dell-omsa-specific 1.3 M smbios-utils i386 2.1.0-1.2 dell-omsa-specific 119 k Transaction Summary ============================================================================================================================ Install 4 Package(s) Upgrade 0 Package(s)
Step 2: Install the OMSA RAC Development Package
The package that contains the racadm CLI utility required to manage your DRAC is included with the srvadmin-racser-devel package. This package has three dependencies, so if they’re not already installed, yum will fix that for you. Type:
yum install srvadmin-racser-devel
and the output should like like:
============================================================================================================================ Package Arch Version Repository Size ============================================================================================================================ Installing: srvadmin-racser-devel i386 5.5.0-364 dell-omsa-specific 196 k Installing for dependencies: srvadmin-omilcore i386 5.5.0-364 dell-omsa-specific 489 k srvadmin-racser i386 5.5.0-364 dell-omsa-specific 12 k srvadmin-syscheck i386 5.5.0-364 dell-omsa-specific 6.6 k Transaction Summary ============================================================================================================================ Install 4 Package(s) Upgrade 0 Package(s)
Step 3: Protect OMSA from being upgraded
If you’re running a Dell PowerEdge 2650, version 5.5 of OMSA is the latest that supports your hardware, so you’ll need to tell yum not to update OMSA to a later version. Edit the /etc/yum.conf file with your favorite text editor and add this line at the bottom:
The next time you run yum update, it will ignore any updates to OMSA.
Step 4: Start the svradmin Service
Now you’re ready to start the svradmin service by typing:
The output should look like:
Starting pppd (RAC) services: [ OK ] Starting racsrvc (RAC) service daemon: [ OK ] Starting pppd (RAC) services: [ OK ] Starting racsrvc (RAC) service daemon: [ OK ]
Step 5: Use racadm
Now you’re ready to manage your DRAC III. Type:
You should get something like:
RAC Information: RAC Date/Time = Tue, 28 Sep 2010 07:32:48 GMT-07:00 Firmware Version = 3.38 (Build 12.14) Firmware Updated = Hardware Version = A04 Current IP Address = 123.456.78.90 Current IP Gateway = 123.456.78.1 Current IP Netmask = 255.255.255.0 DHCP enabled = FALSE Current DNS Server 1 = 220.127.116.11 Current DNS Server 2 = 18.104.22.168 DNS Servers from DHCP = FALSE PCMCIA Card Info = N/A System Information: System ID = 0121h System Model = PowerEdge 2650 BIOS Version = A21 Asset Tag = Service Tag = 2T10V21 Hostname = hostname.domainname.com OS name = Linux 2.6.18-164.9.1.el5 ESM Version = 3.38 Watchdog Information: Recovery Action = No Action Present countdown value = 0 Initial countdown value = 6553 RAC Firmware Status Flags: Global Reset Pending Flag = 0
Step 6: Reset the DRAC password
The default username/password on a DRAC III is root/calvin, and the default user index number for root is 1, which you’ll need to know when you type this command to change the password:
racadm config -g cfgUserAdmin -o cfgUserAdminPassword -i 1 'newpassword'
Notice that the new password should go inside apostrophes. That allows you to use special characters (! ? #) in your password.
If the default admin username has been changed, you can display it from the command line with:
racadm getconfig -g cfgUserAdmin -i 1
Now reset the DRAC so it accepts the change:
Give the DRAC a few moments to reset, then (assuming you have a network cable connected to it) try to connect to it using the IP address assigned to it (you can also use racadm to edit the DRAC’s network settings).
Congratulations! You now have control of your DRAC!
