Reset lost iDRAC pass from OMSA

I was recently playing around with EM7 and various Dynamic Apps around Dell hardware.  I came to find that my remote server (hosting this site) had storage in a ‘nonCritical’ state.  I promptly tried logging into my idrac for the system and was having issues getting in.  I had forgot what I had set for the password on the root and personal accounts.  (For those that leave it root/calvin, shame on you!)  This set off a “fear” if you will of having to shut down several VMs and get the datacenter hosting it to attach a remote KVM so I could change the drac password.  I hate this thought.  I spent 30 seconds here and there trying every password I could think of but nothing worked.  I finally started googling around to see if there was any other method.  I struck a winner.

So first thing is you will need Dell Open manage installed on the host system.  From what I can tell this wont work otherwise.  I wrote up a short on installing Dell OpenManage on an Ubuntu 16.04 system previously.

I quickly found that racadm is not properly setup for x64 systems.

/opt/dell/srvadmin/sbin/racadm: line 3: /opt/dell/srvadmin/lib/srvadmin-omilcore/Funcs.sh: No such file or directory

/opt/dell/srvadmin/sbin/racadm: line 13: printf: 0x: invalid hex number
ERROR: Unable to communicate with RAC controller. Please make sure that a RAC
controller is present in the server and appropriate software is installed.

Thankfully it looks like it was just missing a couple of things in the lib folder that are in lib64.

cd /opt/dell/srvadmin/lib
ln -s ../lib64/srvadmin-deng/
ln -s ../lib64/srvadmin-idrac/
ln -s ../lib64/srvadmin-isvc/
ln -s ../lib64/srvadmin-omacore/
ln -s ../lib64/srvadmin-omilcore/
ln -s ../lib64/srvadmin-storage/

After that, racadm appears to work on the hostsystem.

After all that, it appears that racadm works locally without needing a user/pass to do anything.  This will help later when I will be working on pushing out LetsEncrypt certs into the iDRACs automatically.  So I ran the following as mentioned on the dell forum post to reset the root password to ‘ThisIsNewPass’.  If you want to change other users, change the 2 to what ever number they are in the user list.

racadm set idrac.users.2.password ThisIsNewPass
[email protected]:~# racadm set idrac.users.3.password ThisIsNewPass
[Key=idrac.Embedded.1#Users.3]
