Gentoo on T5240

Hi all,

Has anyone experience with a T5240 (Niagara 2) and Gentoo please?

Besides of that, thanks for the work on porting Gentoo to sparc!
Great work!

Bye

Guenther

I'm just trying to install Gentoo 2008.0 for SPARC on an LDOM in a T5240 this week. I can boot the CD, but once it's loaded a kernel it can't find my virtual cdrom or virtual hardrive anymore and can't continue the boot process.

No answers here I'm afraid, but I'm guessing the kernel doesn't understand the hardware/firmware in a T5240 yet.

Support for running Linux on an LDOM was introduced in 2.6.23. The livecd used 2.6.24 but sadly CONFIG_SUN_LDOMS wasn't turned on.

The next cd will probably have it. For now there's a tftpboot image with ldom support. Can you give it a try?

You are better than 16 hours of searching on google!!!

...now I have to set up this tftp thing. Never had to before. Hmmm.. Do I have to have the tftpd server on the same subnet?

I have to dodge work, but I'll have results with a week.

Thanks again!!!

Netbooting works using mac addresses so they have to be on the same switch/hub for the (r)arp request to get through

No good news. I'm really not sure if I'm even doing everything right, but I had to setup the TFTP server on another Solaris 10 box. After a pile of poking around I finally managed to "boot net" and get a response. I'm using the boot image that you linked to (above) of course:

You can see the kernel is 2.6.28-rc8, and I'm booting a sun4v T5240, but the rest is gobledeegook to me.

(Just to be clear, the machine that's trying to "boot net" is a LDOM inside the T5240 with 8 threads, 16GB of RAM, and a 137GB virtual disk given to it.)

Hmmmm.... interesting. Is:

a bad sign?

Hi,

I also want to install gentoo on an LDOM (T1000).

Is it possible to use the last autobuild-cd (HOW?),

EDIT= with LDOM 1.1 it should be possible (iso or dvd ->Logical Domains (LDoms) 1.1
Administration Guide from docs.sun.com )

or does someone has a "basic" disk-image for me,

or ist there a working tftp-image?

Regards

Dony

Hi,

my "LDOM-Gentoo" ist running

I installed gentoo on a my Blade 1000 (external 4GB drive) and dd the whole disk in a file.

First I had problems with udev but with ~sparc and udev-140 and 2.6.29 it works perfect.

Kernel-Config:

CONFIG_SUN_LDOMS=y
CONFIG_SUNVDC=y
CONFIG_SUNVNET=m ("sunvnet" in /etc/modules.autoload.d/kernel-2.6)

In SILO / fstab you have to change /dev/sdXY to /dev/vdiskXY (here /dev/sda1 -> /dev/vdiska1)

Regards

Dony

I'm really not a sun expert but do you think the netboot installation way could have helped you [1] ?

dony · Post by **dony** » Thu Apr 02, 2009 3:17 pm

Hi nico_calais,

I tried some netboot-images but not one of them worked ... (some had panics, in some the LDOM-stuff was not in the kenrnel)

If you will have a working image it will be the fastes way of LDOM-Installation.

If you have another Sparc to install it my way it is the easieset way

I hope the LDOM-stuff will be in the kernel of the autobuilds in the future -> that will be the fastest AND easieset way:

Make the iso visible as vdisk to the LDOM, create new vdisk for installation (mkfile, slice or disk) and boot / install gentoo.
