Figure 4-61 illustrates the boot loader options during the installation. By default, RHEL 5.5 will install the GRUB boot loader. Notice that, like the partition and file system layout, the multipathing device will also be used for the boot loader installation. Click Next to continue the installation process. Figure 4-61 RHEL 5.5: Boot loader panel 254 SAN Boot Implementation and Best Practices Guide for IBM System Storage
Lastly, during the RHEL 5.5 installation, you need to verify that the boot loader will also utilize a multipath device. Figure 4-62 shows the installation panel that is used to configure the boot loader installation. Notice that, in this example, the /dev/mapper/mpath0 device is used. Figure 4-62 RHEL 5.5: Boot loader installation panel 4.8.3 Post operating system installation considerations After the installation of RHEL 5.5 has completed, the XIV Host Attachment Kit (HAK) must be installed to complete the multipathing configuration process. Because the HAK has OS package prerequisites associated with the HAK, a review of the associated HAK release notes, for the version to be installed, is highly recommended prior to the start of the installation. Example 4-14 shows the execution of the installation script. Example 4-14 Installation of the XIV HAK for RHEL 5.5 # tar -xzvf XIV_host_attach-1.5.2-rhel5-x64.tar.gz # cd XIV_host_attach-1.5.2-rhel5-x64 # /bin/sh ./install.sh Welcome to the XIV Host Attachment Kit installer. Required OS packages: +--------------------------+-----------------+-----------------+ | RHEL | SLES 11 | SLES 10 | +--------------------------+-----------------+-----------------+ | device-mapper-multipath | multipath-tools | multipath-tools | | sg3_utils | sg3_utils | scsi | +--------------------------+-----------------+-----------------+ NOTE: Installation would FAIL if any of the above packages is missing.
