Overview

HPE 3PAR ODM 3.1 for IBM AIX MPIO (QL227-10503) is a standalone software package that delivers a highly available, robust, and trouble-free multi-pathing solution for IBM AIX deployments. With MPIO for IBM AIX, I/O is intelligently routed through multiple paths between a host server and the HPE 3PAR Storage System for greater availability and load balancing. This solution is designed to utilize all available paths to prevent overloading of any single path and the accumulation of I/O bottlenecks. Simple administration and affordability make MPIO for AIX an ideal solution for enhancing performance and reliability in IBM AIX environments.

 

HPE 3PAR ODM 3.1 for Veritas VxDMP (QL227-10504) provides a single path ODM entry for the 3PAR devices. This allows Storage Administrators to identify and manage the 3PAR devices in a Veritas environment.

 

HPE 3PAR ODM 3.1.1.0 Software for IBM AIX MPIO Update (QL227-10514) is an update that is installed on to the HPE 3PAR ODM 3.1 for IBM AIX MPIO Base product.

HPE 3PAR ODM 3.1.1.0 Software for IBM AIX MPIO Update adds two new features:

The default setting is round_robin. The native chdev command can be used to change to shortest queue on a per LUN basis.

  • timeout_policy
    • Adds new fail_path and disable_path settings to the existing retry_path value.
    • Sets the default to fail_path as recommended by IBM.

Note: The native chdev command can be used to change to “retry_path” or “disable_path” on a per LUN basis.
