6. As shown in the output, the boot configuration needs to be modified to use the new
created MPP initial RAM disk.
Edit /boot/grub/menu.lst and make a copy of the existing boot entry to start the operating
system. Modify the name of the initial RAMdisk to the name of the RAMdisk that contains
the MPP driver support. Usually the word initrd is replaced with MPP. Example 17-12
shows a partial content of the boot loader GRUB config. The first section is used to boot
the system with the initial RAMdisk that contains the MPP driver support and the second
section uses the standard initial RAMdisk. We recommend using the MPP initial RAMdisk
entry as the default boot entry in the configuration. Usually this is achieved by having this
boot configuration as the first boot configuration defined in the config file.
Example 17-12 GRUB configuration file menu.lst

7. Do not reboot until after the DS3300 is configured as described in the next section.

17.5 Setup the DS3300 logical drives and host mapping

The basic network setup needs to be done as described in 4.4.8, "(Optional) Change network
configuration" on page 88. The iSCSI interface ports of the DS3300 must be configured with
the correct IP addresses, as described in 12.2.3, "Configure iSCSI Host Ports" on page 276.
You might also want to install a separate management station to run the DS3000 Storage
Manager if Storage Manager is not installed on the host. See Chapter 5, "Installing IBM
System Storage DS3000 Storage Manager" on page 93 for details on installing Storage
Manager.
This section will describe the configuration that was done to provide two logical drives
configured on an IBM System Storage DS3300 to the host HOOGHLY running Red Hat

add a new boot menu, which uses mpp-2.6.9-55.ELsmp.img as the initrd
Now Reboot the system for MPP to take effect.
The new boot menu entry should look something like this (note that it
vary with different system configuration):
