For Red Hat Enterprise Linux 5:
Edit the settings copied in step 26 so that the root specification is
used for HDLM startup.
Before:
root=LABEL=/
After:
root=/dev/sddlmca2
¢
For OSs other than the above:
Delete the root specification in the configuration that you copied in
step 26. If you are using a Xen kernel, delete the root device
specification in module. For details on Xen kernels, see Table 3-61 Xen
Hypervisor Operating Environments Supported by HDLM on page
3-93 .

.
Specify the initial RAM disk image file created in step 24 for initrd
contained in the boot loader configuration file.
Change the initrd specification in the configuration that you copied in
step 26. If you are using a Xen kernel, change the initrd file name
specified in module to the initial RAM disk image file you created in step
24. For details on Xen kernels, see Table 3-61 Xen Hypervisor Operating
Environments Supported by HDLM on page 3-93 .
Keep in mind that the specification method for initrd differs depending
on the boot loader.
