Using Uuids In The Boot Loader And /Etc/Fstab File (Ia64) - Novell LINUX ENTERPRISE SERVER 10 - STORAGE ADMINISTRATION GUIDE 7-2007 Administration Manual

If you use the Boot Loader option in YaST, there is a defect where it adds some duplicate lines
to the boot loader file when you change a value. Use an editor to remove the following
duplicate lines:
color white/blue black/light-gray
default 0
timeout 8
gfxmenu (sd0,1)/boot/message
When you use YaST to change the way that the root (/) device is mounted (such as by UUID or
by label), the boot loader configuration needs to be saved again to make the change effective
for the boot loader.
6 As the root user or equivalent, do one of the following to place the UUID in the /etc/
fstab file:
Open YaST to System > Partitioner, select the device of interest, then modify Fstab
Options.
Edit the /etc/fstab file to modify the system device from the location to the UUID.
For example, if the root (/) volume has a device path of /dev/sda1 and its UUID is
e014e482-1c2d-4d09-84ec-61b3aefde77a, change line entry from
/dev/sda1
to
UUID=e014e482-1c2d-4d09-84ec-61b3aefde77a
acl,user_xattr
IMPORTANT: Make sure to make a backup copy of the fstab file before you begin,
and do not leave stray characters or spaces in the file.
3.4 Using UUIDs in the Boot Loader and /etc/
fstab File (IA64)
After the install, use the following procedure to configure the UUID for the system device in the
boot loader and /etc/fstab files for your IA64 system. IA64 uses the EFI BIOS. Its file system
configuration file is /boot/efi/SuSE/elilo.conf instead of /etc/fstab.
1 Install the SUSE Linux Enterprise Server for IA64 with no SAN devices connected.
2 After the install, boot the system.
3 Open a terminal console as the root user or equivalent.
4 Navigate to the /dev/disk/by-uuid directory to find the UUID for the device where you
installed /boot, /root, and swap.
4a At the terminal console prompt, enter
cd /dev/disk/by-uuid
4b List all partitions by entering
ll
4c Find the UUID, such as
e014e482-1c2d-4d09-84ec-61b3aefde77a —> /dev/sda1
5 Edit the boot loader file, using the Boot Loader option in YaST2.
For example, change
/ reiserfs
1 1
acl,user_xattr
/ reiserfs
