Scripted installs If multiple LUNs are visible to the HBA, the Red Hat Linux Kickstart file will install Linux partitions across the available LUNs by default. In most cases, it is best to place the OS partitions on the first LUN. To do this, copy and rename the Kickstart file. Then add the following text to the end of each part command: --ondisk=sda On Red Hat Enterprise Linux 3, you must specify the location of the bootloader. To place the grub bootloader on the first LUN, add the following text to the end of the bootloader command in your Kickstart file: --driveorder=sda Copy and modify the desired job to point to the modified Kickstart file. Make sure to install the OS in a single path configuration. Setting up two paths to the LUN (for example, through both HBAs on a blade) will result in one of these two things: • An OS failure due to a drive that is "unformatted, damaged, or formatted with a file system that is incompatible" • Returned errors such as "Invalid Partition" To resolve the issue, either remove one of the HBA cables or set up the SAN switch zoning to allow access to the LUN from only the first HBA and one array controller port. After the OS finishes installing, install the multipathing software and enable the second HBA to access the LUN. 6

Scripted installs
If multiple LUNs are visible to the HBA, the Red Hat Linux Kickstart file will install Linux partitions
across the available LUNs by default. In most cases, it is best to place the OS partitions on the first
LUN. To do this, copy and rename the Kickstart file. Then add the following text to the end of each
part command:
--ondisk=sda
On Red Hat Enterprise Linux 3, you must specify the location of the bootloader. To place the grub
bootloader on the first LUN, add the following text to the end of the bootloader command in your
Kickstart file:
--driveorder=sda
Copy and modify the desired job to point to the modified Kickstart file.
Make sure to install the OS in a single path configuration. Setting up two paths to the LUN (for
example, through both HBAs on a blade) will result in one of these two things:
•
An OS failure due to a drive that is “unformatted, damaged, or formatted with a file system that is
incompatible”
•
Returned errors such as “Invalid Partition”
To resolve the issue, either remove one of the HBA cables or set up the SAN switch zoning to allow
access to the LUN from only the first HBA and one array controller port. After the OS finishes
installing, install the multipathing software and enable the second HBA to access the LUN.
