RMU build Gen-1.5: IV. Best Practices - B. Install RACADM Tool on RMU

This page is part of the Gen-1.5 RMU build runbook.

Go back to the previous section: A. Proxmox Security

B. Install RACADM Tool on RMU (Optional)

The following section relates to sites with Dell node machines. This will enable your rmu to access the iDRAC interface on the Dell servers for the purpose of updating the iDRAC settings, access an emergency console shell on the Dell server, etc.

1. On the Proxmox WebUI, select the RMU on the left panel, select Shell near the top right.
   • 
2. Execute the following commands

   echo 'deb http://linux.dell.com/repo/community/openmanage/11010/jammy jammy main' | sudo tee -a /etc/apt/sources.list.d/linux.dell.com.sources.list
   wget https://linux.dell.com/repo/pgp_pubkeys/0x1285491434D8786F.asc
   apt-key add 0x1285491434D8786F.asc
   apt-get update
   apt install gpg libssl-dev -y
   apt install srvadmin-idracadm8 -y
   

3. For example, to fix the iDRAC configuration so that the teleport server is able to forward the iDRAC web interface, these commands will have to be executed in a shell on the RMU for each Dell Node machine
   • Disable SSL Header check to (mostly) enable Teleport access to iDRAC:

     racadm -r 10.10.100.55 -u root -p <password> set idrac.webserver.HostHeaderCheck 0
     

     NOTE: The password used in the following is the password used to access the iDRAC/BMC of your Dell Nodes. If the password has not been reset, it can be found physically on the server in the pull-out tab on the front face of the server. If it has been reset, you need to use the current password. If that password is not known, you need to use a physical console (”crash cart”) and boot the server into an iDRAC recovery mode to reset it. See IDRAC access and TSR logs.
