Viewing the Disk Path Information on a Host

Viewing the Disk Path Information on a Host

This section describes how to view the disk path information on a host and know the initiator, storage device, and path status corresponding to the disk.

Prerequisites

The UltraPath software has been installed on the host.

Procedure

  1. Log in to the CLI of UltraPath on the host.
  2. Run show path to show a disk on the host.

    NOTE:
    • If UltraPath is installed on a Windows/Linux/AIX operating system, see the UltraPath User Guide for that specific operating system to know how to use the show vlun command.
    • If the operating system is HP-UX where the Native Multi-Pathing (NMP) software is installed, run scsimgr lun_map to show a disk on the host.
    The following is the disk path information on an AIX host queried by the UltraPath software:
    UltraPath CLI #0 >show path
