the appropriate sized partition. The guidelines depend on whether /hptc_cluster is located
on an HP StorageWorks Scalable File Server (SFS) or is created on the local system disk.

Node”
2.1.5.1 Determining The Size of /hptc_cluster When It Is Located On An SFS Server
If you plan to create the /hptc_cluster an SFS file share, use one of the following calculations
to determine the size of the/hptc_cluster file system:
• If improved availability of services will be configured on the system, use this calculation:
(8.8 MB * Number of nodes) + 1.75 GB for additional directories and files
• If improved availability of services will not be configured on the system, use this calculation:
(5.4 MB * Number of nodes) + 1.75 GB for additional directories and files
2.1.5.2 Determining The Size of /hptc_cluster When It Is Located On A Local Disk On The Head
Node
Follow this procedure if you want to create the /hptc_cluster partition on the local system
disk, and the default maximum limit of 4 GB is too small:
1. Begin the Kickstart installation on the head node.
2. Answer no when the following prompt appears because you will manually create the file
system in the next step:
Do you want to create the XC global file system
(/hptc_cluster) as a partition on the system disk? (y/n) n
Continue with the Kickstart installation of the head node.
3. After the head node is installed, but before running the cluster_config utility to configure
the system, create and mount an /hptc_cluster partition from the space remaining that
is remaining on the local system disk.
Use standard Linux administration procedures to create an appropriately sized
/hptc_cluster partition and modify the /etc/fstab file accordingly.
Use the following guidelines to determine the appropriate size of the /hptc_cluster
partition:
• If improved availability of services will be configured, use this calculation: (8.8 MB *
Number of nodes) + 1.75 GB for additional directories and files
• If improved availability of services will not be configured, use this calculation: (5.4 MB
* Number of nodes) + 1.75 GB for additional directories and files
4. After you create and mount the /hptc_cluster partition, continue with the remainder of
the cluster configuration process.
2.2 Task 1: Gather Information Required for the Installation
Before beginning the installation, read through the following items to make sure you are prepared
to supply the information required by the installation process.
1. Ensure that you have performed all preinstallation tasks described in “Preparing for a New
Installation” (page 23), especially the hardware preparation tasks.
2. Know how to use a text editor (such as vi, emacs, or gedit) because at some points in the
system installation and configuration process, you are required to modify text files.
3. Know the chip architecture for the HP Cluster Platform, which is listed in Table 2-5.
