Re: [Oscar-users] SATA DISKS

Hi Bernard,

I did use the Mueller's kernel (just copied it to /tftpboot/ and PXE boot the node) and no difference... The node tells DISKS=0, and that can not stat /dev/sda

I attach the oscarinstall.log, not found a log in the node.

Really sad to say that this is not a test, but we urgently need this small cluster for a project, they provided us the hardware 2 months later than we asked them!

Thanks,
Carlos

Hi Carlos:

It doesn't really matter whether you use scsi or ide .disk file as this will actually be determined for you (whether your system uses sda or hda) on the fly. This therefore allows you to use the same image on cluster nodes that have either SCSI or IDE disks. This is an enhancement we have contributed to the SystemImager project.

Back to your issue with SATA disks... can you give us the error log if you use Peter Mueller's kernel? That is probably your best bet giving the fact that SystemImager 3.5.3 is bundled with OSCAR 4.2.1.

SystemImager 3.6.3 and the soon to be released 3.7.3 have a new functionality called UseYourOwnKernel which allows you to use your existing OS' kernel along with a generated initrd.img that should allow it to recognize the hardware during imaging, as long as the OS supports it. This is a very powerful new functionality that should potentially solve all hardware module related issues we have been having so far with SystemImager.

Are you currently doing testing? Because a newer version of SystemImager is included in OSCAR trunk, so perhaps you can test that out... it is known to work with RHEL4 - see these posts:

Also we could use some more testers... :-)

Thanks,

Bernard

Subject: [Oscar-users] SATA DISKS

Hello,

We are triying to create a cluster with new SATA machines, and we are
not able beause sis doesn't find the disk.
We are using oscar 4.2.1b5 and RHEL4, and check that /tftboot/kernel is
the same as t http://world.anarchy.com/~peter/systemimager/.
<http://world.anarchy.com/%7Epeter/systemimager/>
I am a bit confused about the /oscarsamples/*.disk to use, scsi or ide?

Thank you,

Carlos
