I've just installed a 3ware raid card, copied, via dd, an old IDE drive to a new drive attached to the raid card and now need to know how to change grub to point to the new drive. Here's what my current grub.conf says on the new drive:

root (hd0,1) install --stage2=/boot/grub/stage2 /boot/grub/stage1 d (hd0) /boot/grub/stage2 0x8000 (hd0,1)/boot/grub/menu.lst quit

I believe I should change the hd0 to sd0....correct? Once I do that, do I need to do something else to get it to setup properly? I changed my fstab already on the new drive.

Tom, I have the same setup as you, except I have 4 IDE drives in RAID 0 on a 4 port Escalade ( 3Ware Card ). Here are my setup files. This may or may not help you out. FSTAB ===== falcon:/etc # cat fstab /dev/sda1 / reiserfs defaults 1 1 /dev/hdb1 /boot ext2 defaults 1 2 /dev/sda3 /home reiserfs defaults 1 2 /dev/sda2 /usr reiserfs defaults 1 2 /dev/hdb2 swap swap pri=42 0 0 devpts /dev/pts devpts mode=0620,gid=5 0 0 proc /proc proc defaults 0 0 usbdevfs /proc/bus/usb usbdevfs noauto 0 0 /dev/cdrom /media/cdrom auto ro,noauto,user,exec 0 0 /dev/fd0 /media/floppy auto noauto,user,sync 0 0 /dev/hdb3 /scratchspace reiserfs defaults 1 2 /dev/hdb4 swap swap pri=42 0 0 /dev/hdc /media/burner auto no,noauto,user,exec 0 0 /dev/cdrom1 /media/cdrom1 auto ro,noauto,user,exec 0 0 /dev/cdrom7 /media/cdrom7 auto ro,noauto,user,exec 0 0 /dev/sdb1 /media/iomega128 vfat default,user,exec 0 0 NOTE: /dev/sda1, /dev/sda2 and /dev/sda3 are all partitions carved out of the single 3Ware raid "disk". MTAB ==== falcon:/etc # cat /etc/mtab /dev/sda1 / reiserfs rw 0 0 proc /proc proc rw 0 0 devpts /dev/pts devpts rw,mode=0620,gid=5 0 0 /dev/hdb1 /boot ext2 rw 0 0 /dev/sda3 /home reiserfs rw 0 0 /dev/sda2 /usr reiserfs rw 0 0 shmfs /dev/shm shm rw 0 0 usbdevfs /proc/bus/usb usbdevfs rw 0 0 /dev/sdb1 /media/iomega128 vfat rw,nosuid,nodev,default,user=jrn 0 0 Again, the /dev/sda1, /dev/sda2 and /dev/sda3 are the partitions carved out of the single 3Ware raid "disk". GRUB MENU.LST ============== falcon:/boot/grub # cat menu.lst gfxmenu (hd0,0)/message color white/blue black/light-gray default 6 timeout 8 title floppy root (fd0) chainloader +1 title failsafe kernel (hd0,0)/vmlinuz.shipped root=/dev/sda1 ide=nodma apm=off acpi=off vga=normal nosmp maxcpus=0 disableapic 3 initrd (hd0,0)/initrd.shipped title Linux-2.4.20-test2 kernel (hd0,0)/linux-2.4.20-test2 root=/dev/sda1 hdc=ide-scsi hdd=ide-scsi title Linux-2.4.21 kernel (hd0,0)/linux-2.4.21 root=/dev/sda1 hdc=ide-scsi title Linux-2.4.21-2 kernel (hd0,0)/linux-2.4.21-2 root=/dev/sda1 hdc=ide-scsi initrd (hd0,0)/initrd-linux-2.4.21-2 title Linux-2.4.21-3 kernel (hd0,0)/linux-2.4.21-3 root=/dev/sda1 hdc=ide-scsi title Linux-2.4.21-test kernel (hd0,0)/linux-2.4.21-4 root=/dev/sda1 hdc=ide-scsi initrd (hd0,0)/initrd-linux-2.4.21-4 title Linux-2.4.22-pre10 kernel (hd0,0)/linux-2.4.22-pre10 root=/dev/sda1 title Linux-2.4.22 kernel (hd0,0)/linux-2.4.22 root=/dev/sda1 hdc=ide-scsi NOTE: root=/dev/sda1 ( this is my 'root' partition ) Again, hope this helps. -Jim-

B--zzzz-T wrong. Grub doesn't care whether a drive is scsi or IDE and it calls them both: hdx So you may not need to change anything... assuming your partitions look the same (are in the same numbering position) as they were. You didn't say enough about your config to comment.

Thanks, Tom
