Thanks for the comments. I will try them and let you know Regards, Mahmood On Friday, April 18, 2014 5:16 PM, John Lauro <john.la...@covenanteyes.com> wrote: Sounds like you are not using default LVM setup? It should just work with LVM.
Generally I prefer just using /dev/sda, /dev/sdb, etc... but LVM is generally safer when devices change... In this case, stick with the UUID or LVM instead of the changeable /dev/sda, etc... If you don't want to switch to LVM, it is possible to boot in rescue mode and manually reinstall grub telling it what the devices will be instead of what they are... been awhile from when I had to do that. Generally not a recommended option for a new install... I think, another option, make your jetflash the lowest priority. As long as D0/D1 are not bootable (you may have to wipe the start of the drives) it should still boot jetflash and the device mappings should then be consistent from the bios. ----- Original Message ----- > From: "Orion Poplawski" <or...@cora.nwra.com> > To: "Mahmood Naderan" <nt_mahm...@yahoo.com>, scientific-linux-users@fnal.gov > Sent: Friday, April 18, 2014 12:59:40 AM > Subject: Re: problem installing SL6.3 from live usb > > On 04/17/2014 04:51 AM, Mahmood Naderan wrote: > > Hi > > Recently I faced problem installing SL6.3 on a machine.
