Unable to Install Ubuntu Server on Dell PowerEdge T710

Asked by Jahangir Alam on 2017-03-13

Dell PowerEdge Server T710, 32 GB RAM, Two 300 GB SCSI Hard Drives coupled as a 600GB virtual disk using RAID 0. Installation takes place smoothly but Ubuntu doesn't boot after installation. Installing from a USB device created using Universal Linux Installer. Placing GRUB at proper location on virtual disk (/dev/hdb in my case). Post installation Grub menu appears but fails to load linux....any suggestions??? BTW I am trying to install Ubuntu Server 12.04 LTS.

Please see the attached FAQ for information on where to find technical support.

Also, it sounds like you're using a FakeRAID setup (most onboard RAID devices fall into this category) and they may or may not work.
If you're using that onboard RAID, try turning it off and re-installing. If you really do need raid, then turn off the onboard RAID and try Software RAID from the installer and see if that is successful.

Typically, the best RAID controllers are the add-in devices. Onboard RAID tends to rely on special drivers to perform most of the work, and don't always work well in Linux in general. Add-In raid controllers have their own processors and the drivers are much more feature complete in Linux.

Dear Lane
I don't think its a fake RAID. Its Dell PowerEdge Server T710 and you could
check its specs here:

http://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/T710-SpecSheet.pdf

It has been shipped with a separate PERC (PowerEdge RAID COntroller). There
is a well defined process of creating RAID through BIOS. I have
successfully used the same configuration in past. The problem started when
one of the SAS disk crashed and we replaced it by a new one. Any other
issue??

So looking way back, as that is a pretty old system, it was last certified in 2012 for 12.04.1. I know you are trying to install 12.04 (probably 12.04.5), so it should work.

That said, this isn't a technical support forum, but the FAQ I linked originally can point you to various places to get technical support, ranging from free (forums and Ask Ubuntu) to paid (Ubuntu Advantage). I would also suggest trying 16.04.

The model certified back then had a Perc 6/i card in it, so if that's the card you have then something is amiss, but all I can really say at this point is that it should work. You may also want to file a bug (https://bugs.launchpad.net/ubuntu/+filebug) however, since 12.04 will fully EOL in April, it is doubtful the bug will be addressed. That's why I suggest also trying 16.04 LTS on this system.

Thanks Lane. Yes I will try 16.04 LTS as well.

Since this is not a tech support forum, that info was provided in a previous reply.
