Dell PowerEdge firmware upgrades via iDrac

Published: 26-01-2018 | Author: Remy van Elst | Text only version of this article

The recent spectre and meltdown vulnerabilities require BIOS and firmwareupdates. Dell provides binaries for Windows and Linux, but just for Red Hat andSUSE. Some firmware updates can be run on Ubuntu or Debian, but some fail withthe error that RPM could not be found. Which is correct since it's not Red Hat.In this small article I'll show you how to upgrade the firmware via the iDrac,which I recently discovered.

Upgrade via the shell

Usually I do upgrades automated with Ansible, via the shell. Manually this canbe done as well, in this example a firmware for the power supply unit of a DellR620:

# Download the firmwarewget Run itbash Power_Firmware_JX7PR_LN_09.2B.80_A00.BIN

On Ubuntu the output in this case is:

Cannot find utilities on the system to execute package.Make sure the following utilities are in the path:rpm stat stty cut fmt tty tar gzip tail rm mkdir mktemp chmod ls basename dirname wc sleep

You could use the iDrac console (if you have an enterprise license) or a KVMswitch to boot up a CentOS live DVD, but in this case there was no KVM orlicense available.

Upgrade via the iDrac

I was unaware of this feature, but using the iDrac web interface you can upgradethe firmware as well. I found this article on the Dell site which explainsit.

Quoting the important parts:

Use the Windows 32-bit or 64-bit version of the Dell Update Package (DUP), which the iDRAC is able to extract and apply by itself.

For iDrac 9:

Go to Maintenance > System Update. The Firmware Update page is displayed.

For iDrac 7/8:

    Go to Overview > iDRAC Settings > Update and Rollback. The Firmware Update page is displayed.

Using the job queue, reboot the machine to apply the update.

This interface has a few advantages over the shell binaries:

It is also possible to SSH into the iDrac and use racadm to upgrade thefirmware. This process involves a remote NFS or SMB share where the upgrade fileis hosted, which we may cover in another article.
