Tru64 UNIX

This user manual for the Tru64 UNIX Logical Storage Manager (LSM) software (version 5.1B or higher, September 2002) provides comprehensive guidance for system administrators on configuring and managing disk storage.

LSM is a host-based disk storage management application that leverages Redundant Arrays of Independent Disks (RAID) technology to create virtual storage pools (LSM volumes) from physical devices. Key benefits highlighted include data loss protection (RAID 1 mirroring, RAID 5 with parity), optimized disk usage by seamlessly combining devices, performance improvements (RAID 0 striping), and enhanced data availability in TruCluster Server environments.

The document covers fundamental LSM concepts, planning configurations, software installation and initialization, and the creation and management of LSM disks, disk groups, volumes, plexes, and subdisks. It also includes detailed sections on troubleshooting, handling special cases (such as upgrades or disk group migration), and utilizing both command-line and the Java-based Storage Administrator graphical user interface.
