I created Raid 0 on all the drives as below:-<BR />LD #1 Raid 0 146GB (dev/cciss/c0d0)<BR />LD #2 Raid 0 73GB (dev/cciss/c0d1)<BR />LD #3 Raid 0 73GB (dev/cciss/c0d2)<BR />I installed Rhat5.1 on LD1(c0d0).After finish installation, i could see the RHat5.1 boot entry on the EFI boot manager and I could boot up. Then I installed RH4(c0d1) and Suse10(c0d2) on my other 2 drives. Installation was completed successsfully but when it reboot after installation complete, I can't boot up to the OS installed on other drives although the boot entry of Rhat4 and Suse 10 appears at EFI boot manager.When i select the entry(Rhat 4 or Suse 10) it says file not found.<BR />When I boot up to Rhat5.1, installed on the 1st drive and mount c0d1 to /mnt/floppy, i could see the files that has been installed on other drives.<BR /><BR />Then I tried installing RH4 on the same drive on different partition on LD1 (C0d0) and i can successfully multiboot.I could also install Suse10 and boot if I install on the 1st drive different partition. <BR />I'm not sure why I cannot setup multiboot when I install the OS on separate drives. Is there anything I need to do for the EFI boot manager to detect my other drives?<BR /><BR />Even at EFI shell, when I switched to fs3: I only can find the files installed on the 1st drive.<BR />I need to setup multiboot from OS installed from different drives but I only can do multiboot from 1 drive now..<BR />Any help on this is much appreciated.<BR />How the EFI boot manager load the OS?<BR />Pls help...<BR /> Sat, 14 Jun 2008 05:57:58 GMT https://community.hpe.com/t5/operating-system-linux/how-to-multiboot-linux-distros-from-different-drive-on-itanium/m-p/4216591#M62211 Usha Devi 2008-06-14T05:57:58Z https://community.hpe.com/t5/operating-system-linux/how-to-multiboot-linux-distros-from-different-drive-on-itanium/m-p/4216592#M62212 Hi,<BR />Try without creating Raid0<BR />it will work<BR /><BR />Logesh S Mon, 16 Jun 2008 02:39:58 GMT https://community.hpe.com/t5/operating-system-linux/how-to-multiboot-linux-distros-from-different-drive-on-itanium/m-p/4216592#M62212 Logesh_1 2008-06-16T02:39:58Z
