Hitachi Dynamic Link Manager Software Users Guide for Linux

¢
For Red Hat Enterprise Linux 6:
a. Change hdlm_dracut=n defined in the /etc/opt/
DynamicLinkManager/hdlm.conf file to hdlm_dracut=y.
b. Execute the dracut command.
If the initial RAM disk image file to be created already exists,
specify the -f parameter to overwrite the file.
The following shows an example of executing the command:
# /sbin/dracut /boot/initramfs-hdlm-2.6.32-71.el6.i686.img
`uname -r`
¢
For OSs other than the above:
Execute the utility for supporting a boot disk (dlmmkinitrd).
If the initial RAM disk image file to be created already exists and you
are using Red Hat Enterprise Linux AS4/ES4 or Red Hat Enterprise
Linux 5, specify the -f parameter to overwrite this file. If you are
using SUSE LINUX Enterprise Server, this file is overwritten even if
you do not specify the parameter.
For details on the dlmmkinitrd utility, see
dlmmkinitrd Utility for
Supporting a Boot Disk on page 7-33.
25. When you create a new initial RAM disk image file rather than overwriting
the existing one, delete the existing initial RAM disk image file that is no
longer required.
26. Copy the configuration contained in the boot loader configuration file,
which was used for startup from the HDLM device.
27. Change the name of the configuration contained in the boot loader
configuration file.
Change the name of the configuration that you copied in step 26. Choose
a name that indicates use for an updated HDLM device specification.
