HP StorageWorks Clustered File System 3.1.1 for Linux Installation Guide (May 2006)

Chapter 4: Install HP Clustered File System 18
If your disk array software allows you to create LUNs, we recommend
that you create three LUNs for the membership partitions. Each LUN
should be a minimum of 8 MB in size. If you are unable to create LUNs on
your disk array, you can use regular disk partitions for the membership
partitions.
You must install a partition table (using fdisk or a similar tool) on the
LUNs that will be used as membership partitions. This implies that the
LUNs are visible to the system. For this to be so, the HBA driver must be
loaded.
To perform this task, use the following command (do not use the
standard linux modprobe command, as it may load the wrong driver
with the wrong settings):
/etc/init.d/pmxs load
At this point it is critical that the MPIO software is correctly functioning
(See “4. Configure MPIO” ). Run the fdisk tool run against the /dev/sdX
device(s) that corresponds to the membership partitions.
It is a somewhat manual process to identify these LUNS. The following
tools are helpful for this purpose:
/opt/hpcfsmgmt/bin/listluns
more /proc/scsi/qla2xxx/*
After the correct membership LUNs have been identified, put a primary
partition table on each LUN using fdisk or a similar tool.
It is important to partition the disks or LUNs appropriately before the
membership partitions are used. If you need to repartition a disk
containing a membership partition later, stop HP Clustered File System
before you change the layout. While the cluster is stopped, you cannot
access other disks in the cluster.
7. Install HP Clustered File System
Install Clustered File System from the product CD or the location where
you have downloaded the software. You will need to install the software
on each server that will be in the cluster. Be sure to install the RPM that
corresponds to your architecture (i586 for 32-bit or x84_64 for 64-bit).
