Force The Ram Disk To Recognize The Root Partition - Novell LINUX ENTERPRISE SERVER 10 - STORAGE ADMINISTRATION GUIDE FOR EVMS Administration Manual

2 Open the boot loader file in a text editor.
For Grub, this is the /boot/grub/menu.1st file. For LILO, this is the /etc/
lilo.conf file.
3 Locate the line that contains the root= parameter.
For example, if your root file system uses device sda1, look for a line similar to this:
kernel (sd0,0)/vmlinuz root=/dev/sda1 vga=0x31a splash=silent
showopts
4 Modify the mount location from /dev to /dev/evms so it can be managed by EVMS.
For example, after the change, the line looks like this:
kernel (sd0,0)/vmlinuz root=/dev/evms/sda1 vga=0x31a splash=silent
showopts
5 Repeat Step 3 and Step 4
6 Save the file.
The changes do not take affect until the server is restarted. Do not reboot at this time.
7 Continue with Section 2.2.5, "Force the RAM Disk to Recognize the Root Partition," on
page 25.

2.2.5 Force the RAM Disk to Recognize the Root Partition

The mkinitrd(8) command creates file system images for use as initial RAM disk (initrd)
images. These RAM disk images are often used to preload the block device modules (SCSI or
RAID) needed to access the root file system.
You might need to force the RAM to update its device node information so that it loads the root (/)
partition from the /dev/evms path.
NOTE: Recent patches to mkinitrd might resolve the need to do this task. For the latest version
of mkinitrd, see Recommended Updates for mkinitrd (http://support.novell.com/techcenter/psdb/

1 At a terminal console prompt, enter the EVMS Ncurses command as the root user or
equivalent:
evmsn
2 Review the output to verify that EVMS shows only the /boot and swap partitions as active in
EVMS.
You should see the following devices mounted (with your own partition names, of course) for
these two partitions:
/dev/evms/sda1
/dev/evms/sda2
3 At a terminal console prompt, enter the following update the initrd image with the /dev/
evms path information for the root (/) partition:
/sbin/mkinitrd -f evms
This does not take effect until you restart the server.
4 Continue with Section 2.2.6, "Reboot the Server," on page
to locate other lines in the file that need to be similarly modified.
