While setting up an OpenStack Swift cluster, I had five Dell R720 servers with incorrectly configured RAID arrays. The two operating system hard drives were configured in a RAID1 array, as expected, but the 24 data hard drives were configured in two RAID5 arrays. The data hard drives in OpenStack Swift storage nodes should not be in a RAID array; Swift simply wants each hard drive on its own.
You can reboot most of Dell’s enterprise servers into the Dell RAID (PERC) Controller to get access to a GUI to re-configure the RAID arrays. But, with five servers and 24 disks on each, using the GUI would have been a very tedious and time consuming task. So, I began looking into what the
racadm command was capable of.
You can SSH to the IP address of a Dell iDRAC and use the racadm command to run all sorts of commands. Luckily, racadm has a set of commands that allow you to reconfigure the RAID arrays.

The Dell iDRAC web interface has always been cumbersome to deal with. However, you can log in via SSH to a Dell iDRAC and use the
racadm command to perform actions against the physical server. Because of SSH, it is possible to automate actions that would otherwise take a long time to do via the web interface.
This post will be an ever growing list of Dell iDRAC racadm commands, scripts, and ways to automate repetitive tasks.

Dell’s Project Sputnik is impressive; not only is the hardware high quality (the Dell XPS 13 is the best laptop I think Dell has ever made), but the simple fact that Project Sputnik started as just that, a project, and morphed into an actual product speaks volumes that Dell wants a presence in the Linux community. This has been further shown with Dell’s recent release of the Alienware X51, also pre-installed with Ubuntu. I’m not aware of any other industry leaders taking such an interest in the Linux community.
