Second Ethernet network: A second Ethernet network is needed to meet the installation requirements of the IBM Platform High Performance Cluster (HPC) and IBM Platform Cluster Manager Advance Edition. For more details about the setup for those products, see 3.1.3, “Infrastructure planning” on page 20.

General Parallel File System (GPFS): GPFS on a Logical Volume Manager (LVM) logical volumes is not supported, but there is a small “as is” suggestion that can be applied to make a working environment. This suggestion proves to be useful in small environments, which are usually for testing purposes. Create the /var/mmfs/etc/nsddevices file (on each NSD server) to define eligible devices for NSD: #!/bin/bash minor=$(lvs -o lv_name,lv_kernel_major,lv_kernel_minor 2>/dev/null | awk '/ gpfslv / { print $3 }' 2>/dev/null) echo "gpfslv dmm" exit 1 Create a GPFS logical volume (LV) on each NSD server: lvcreate -n gpfslv -L 150G rootvg Create the /dev node (GPFS needs the device node to be defined directly under /dev): ln -s /dev/rootvg/gpfslv /dev/gpfslv From this point, you can follow the GPFS Quick Start Guide for Linux: http://www.ibm.com/developerworks/wikis/display/hpccentral/GPFS+Quick+Start+Guide+for+Linux
