After The Server Install - Novell LINUX ENTERPRISE SERVER 10 - STORAGE ADMINISTRATION GUIDE 7-2007 Administration Manual

2.1.3 After the Server Install

After the SUSE Linux Enterprise Server 10 install is complete, you must perform the following
tasks to ensure that the system device functions properly under EVMS:
Edit the /etc/fstab File
When you boot the system, the kernel reads the /etc/fstab file to identify which file systems
should be mounted and then mounts them. This file contains a table of file system information about
the root (/), /boot, and swap partitions plus other partitions and file systems you want to mount.
The /boot partition is separate from the EVMS container where you placed the root (/) and swap
partitions and is not managed by EVMS at this time. However, in the following steps, you disable
boot.lvm and boot.md, then enable boot.evms. In effect, this forces EVMS to scan all the
partitions at boot time, including the /boot partition, and it activates /boot under the /dev/
evms directory. Therefore, this makes /boot a partition that is discovered by EVMS at startup,
and requires that the device be listed under /dev/evms in the fstab file so it can be found when
booting with boot.evms. You must edit the /etc/fstab file to modify the location of the /
boot partition so it is under the /dev/evms directory.
In fstab, the entry for the boot device might present the boot device by the device node name
(such as /dev/sda1) or by the UUID pathname (such as /dev/disk/by-id/scsi-
SServeRA_Drive_1_600BC00000-part1). In ether case, that name for the boot device must
be changed to include evms in the path, such as /dev/evms/sda1.
The procedure in this section shows how to change /dev/sda1 to /dev/evms/sda1. Replace
sda1 with the device name of the device you used for your /boot partition.
IMPORTANT: When working in the /etc/fstab file, do not leave any stray characters or
spaces in the file. This is a configuration file, and it is highly sensitive to such mistakes.
To modify the path of the boot device in the /etc/fstab file, complete the following procedure:
1 Open the /etc/fstab file in a text editor.
2 Locate the line that contains the /boot partition.

IMPORTANT: After the install is complete, make sure to perform the mandatory post-install
configuration of the related system settings to ensure that the system device functions properly
under EVMS. Otherwise, the system fails to boot properly.

For example, if your /boot partition uses device sda1 and the Reiser file system, look for a
line similar to this:
