Updating RAMDISK Image [Linux only]
Update /boot/initrd-<kernel version>.img (/boot/initramfs-<kernel version>.img in RHEL6
or later) as RAMDISK image after installing, updating or uninstalling the device driver.
Check the boot loader configuration such as grub.conf or elilo.conf. If you find the files as
different name, update your RAMDISK image using the procedure below:
● Procedure for updating RAMDISK image
Execute the mkinitrd command according to the following procedure:
# cd /boot (for IA-32/x86_64)
# cd /boot/efi/efi/redhat(for IA-64)
# /sbin/mkinitrd –f <image-file-name>.img <kernel version>
● Notes on using Hitachi Dynamic Link Manager Software (HDLM)
Update the RAMDISK image file for HDLM in the SAN boot environment using HDLM.
Refer to the HDLM User's Guide when using the SAN boot environment using HDLM.
Precautions on setting 'FORCE DEFAULT
PARAMETER'
When you set 'Force Default Parameter' to enabled , the driver program operates with
default parameter settings ignoring the parameter settings shown by the following table. Do
not set, modify and delete parameters by executing hfcmgr when 'Force Default
Parameters' is enabled. You should set, modify and delete parameters after you change
'Force Default Parameter' to disabled and reboot OS.
