For example:
# mkinitrd -f -v /boot/initrd-2.6.18-53.el5.img 2.6.18-53.el5
NOTE: For RHEL 6, rebuild the ramdisk image using the dracut command:
# /sbin/dracut -v -f /boot/<ramdisk image name> <kernel-version>
4. Perform one of the two following actions to verify that all the required drivers are added to
the ramdisk image:
• Check the verbose output. For example:

• Check the contents of the /etc/grub.conf or /boot/grub/grub.conf with grub
as the bootloader so that the initrd maps to the correct ramdisk image.

Setting Up the NVRAM and BIOS with the QLogic HBA
This section describes how to set up the NVRAM and BIOS with the QLogic HBA.
Configure the following NVRAM settings for QLogic 23xx, 24xx and 25xx cards using the QLogic
Fast!UTIL. Access the Fast!UTIL utility by hard booting the server and, when prompted and follow
these steps:
NOTE: The NVRAM settings on QLogic HBAs can be changed by any server in which they are
installed. These settings will persist for an HBA even after it is removed form a server. To obtain
the correct settings for this configuration, you will be instructed to return all NVRAM settings to
their default settings.
1. Enter Fast!UTIL by pressing Ctrl-Q when prompted.
NOTE: Each HBA port is reported as a host bus adapter and the following settings need to
be made for each of them.
