Feedback on the Dell PowerEdge R300

Asked by Hans on 2011-09-06


I just tried to install ubuntu-10.04.3-server-amd64.iso several times on a Dell Power Edge R300 Server - and failed. After Install, the operating system is not found ("Missing opearting system") and I wonder if it´s a raid controller issue. I also tried different ways of partitioning, also a small ext2 partition on the beginning of the harddisk for /boot to prevent bootloader issues on the 750GB RAID1 harddrive. But still OS is not found.

I did not find exactly the same problem on internet forums but lots of grub problems regarding R300 and recent Ubuntu Server releases. So I wonder that R300 is "certified" from Ubuntu??

Here is some information about my R300 system:

1x 2,5 GHz QuadCore Xeon X3323
LSI SAS1068E PCI-Express Fusion-MPT SAS Controller (rev08)ls

I'm not sure what the issue here is, though my guess would be a RAID issue of some sort. Out of curiosity, what is your exact RAID setup?

The system we tested has two SAS hard disks in a RAID 0 config using the same controller you have and I just installed 10.04.3 this morning on that system and did a full update to the latest SRUs as well.

Also, the error you're getting "Missing operating system" sounds more like a BIOS message than it does a grub message (e.g. the BIOS is telling you it can't find a boot loader") so it's entirely possible that your installation is completing successfully but there's another issue at a deeper level. It's also entirely possible that the grub install is failing at the end of the install for some reason.

Be that as it may, I'm unable to reproduce this issue on our R300. You can compare components in our system to yours by going here:

yes I wonder why it´s not working. Before trying Ubuntu, we had an OpenSUSE on the server that installed without any problem.

It´s a simple RAID-1 with two 750GB SATA disks. Here are parts of the controller menu:

I will have a closer look at the GRUB installation then.

Thank you for your help.

I found out that the DRAC5 remote management card caused the trouble.

In the card you can activate virtual flash drives that appear on the system as a harddrive. This messed up the drive letters and the system is not booting when virtual media are accessible in the boot menu. I Did not find out if this makes BIOS or grub fail, but with a SuperGrub2 disk I can boot in the installed system.

Installing a system remote by DRAC5 card or directly at side failed when having logged in the DRAC card; however, when I took the server to my workplace, not connected to the DRAC card, and with virtual flash deactivated in the card´s menu, it installed and booted without any problem.

BTW, the pipe symbol is missing in the DRAC5 virtual console. Seems to be designed mostly for Windows OS.

Again, thank you for your help!

Glad it worked out... That's interesting though. I'm not terribly familiar with the DRAC5 but I'm assuming it's the Dell equivalent to IBM's RSA modules. I am quite familiar with those, though I never encountered one that had externally visible onboard storage.

At a guess, I'd imagine those virtual flash drives you mention are for hosting hypervisors for virtualization setups so that you can run your hypervisor off a small dedicatd flash module and store your VMs on large arrays inside or outside the host machine.

In any case, it seems that you could probably do some manual partitioning and either bypass the flash on your DRAC 5 module, or incorporate it (use it for primary OS storage and use hard disks for data storage and /home, /var, etc)

Good luck!
