Prepare for Deployment of Operating Systems

Begin dual-boot configuration by preparing for the OS deployment to the compute nodes. Be sure to read through this entire document before beginning installation. It is also important to become familiar with the product documentation; for related links, see Appendix 5.

Prepare for SUSE Linux Enterprise Server Deployment

In this setup, SUSE Linux Enterprise Server 10 SP1 was deployed as the first OS from a dedicated deployment server by using AutoYaST, the Novell automated installation mechanism.

Note: Because AutoYaST uses unicast-based and file-based installation, it might not scale successfully for a very large number of nodes (the maximum simultaneous installations is usually 40-50 nodes).

To prepare for SUSE Linux Enterprise Server deployment, configure the deployment server, create the AutoYaST control file, and integrate the Linux HPC software into the repository.

Configure the Deployment Server

The deployment server must be connected to the private network of the cluster, and must be assigned a static IP address that is in the private network range. The following section describes the procedures that are used to configure the deployment mechanism on SUSE Linux Enterprise Server 10 SP1. It is possible to use other hardware and software

configurations. You should modify the procedures based on your particular configuration.

1. Install SUSE Linux Enterprise Server 10 SP1 on the deployment server.

a. Disable the the firewall after the installation. To do this, launch YaST

(Computer->YaST) and open Security and Users->Firewall. In the Service Start section choose Manually, then choose Stop Firewall Now in the

Switch On and Off section. Click Next and then Accept to save settings and shut off the firewall. Once you've got the configuration set and have

successfully performed a PXE boot installation, you can re-enable the firewall with the allowed service ports, if desired (they are: NFS 2049, TFTP 69, DHCP Server 547 and others as needed).

2. Configure a network installation source using YaST Installation Server module

a. Launch YaST (Computer->YaST), browse to the Miscellaneous section and

open Installation Server. The first time you launch the Installation Server module, you'll be prompted to set up an HTTP, FTP or NFS installation source. Choose NFS. In this example, an ―/install‖ directory was created at the root of the file system to contain the installation sources.

b. On the following screen you are prompted to enter a Host Wild Card and

Options for the NFS share. Enter “*” (asterisk) in the Host Wild Card field, “ro” in the Options field and click Next. (If the ―Unable to write idmapd.conf‖ error pops up you can safely ignore it)
