Method and System for Automated Discovery and Input of Static Bootup Network Information for Multiple Logical Partitions (LPARs)

Disclosed is a method and system for automated discovery and input of static bootup network information for multiple Logical Partitions (LPARs). Client IP addresses associated with the multiple LPARs are obtained from the static bootup network information and are used for installing the multiple LPARs.

In a cloud computing environment, multiple LPARs are generally installed by booting a single LPAR from the multiple LPARs into a System Management Service (SMS). Thereafter, unique identifiers corresponding to the remaining LPARs are manually entered for installation of the remaining LPARs. Alternatively, an
'lpar

_netboot' command of a Hardware Management Console

                                        (HMC) is used from a Secure Shell (SSH) terminal session. In this case, the command is repeated for every LPAR with client IP addresses within a subnet of IP addresses. However, discovering client addresses within the SSH terminal session is a challenge.

The method and system disclosed herein uses a script for discovering the client IP addresses. The script executes in a loop and the output from the script which contains static bootup network information is provided to a specified link, which parses the client IP addresses from the output. Thereafter, the parsed client IP addresses are provided to the 'lpar

_netboot' command.

For a subnet 10.33.0.0 and netmask 255.255.0.0, the following script enables installation of upto 216 LPARs.
