AlphaServer GS140

This document provides instructions for configuring and managing logical partitions on an AlphaServer GS140 system. It covers hardware requirements, console firmware configuration, and procedures for initializing, booting, and managing separate instances of an operating system across up to three logical partitions. Key topics include:

• Configuration Rules: Hardware prerequisites for partitioning, including CPU, memory, and I/O module allocation, as well as PCI card cage and console terminal requirements.
• Environment Variables: Defining partitions using lp_count, lp_cpu_mask, lp_io_mask, and lp_mem_mode variables.
• Setup and Boot: Step-by-step console command sequences to initialize partitions from the primary console and boot operating systems on secondary partitions.
• Tips and Troubleshooting: Procedures for handling hung partitions, reconfiguring the system, and using debug tools like DECevent within partitioned environments.
