DSPHMCINF/DSPSMDTA: Querying the Current Status of Every HMC or SM Straight from the Command Line

Resolving The Problem

This document describes and contains two commands that can be used to query the current status along with some useful information of every HMC (Hardware Management Console) or SM (System Manager) acknowledged by your server, straight from the i5/OS or IBM i command line.
The commands are Display HMC Information (DSPHMCINF) and Display System Manager Data (DSPSMDTA).

Caution: The following command is provided on an unsupported, as is basis.

Prompting on the DSPHMCINF command displays the following:

Display HMC Information (DSPHMCINF)

The following is the online help for the command. You can press the F1 anytime in the command to reach the help information:

: The Display HMC Information (DSPHMCINF) command lets you know the :
: current network configuration of every Hardware Management Console :
: that is currently acknowledged by your Server. :
: :
: The HMC information is returned as a string containing a set of :
: keywords with information about the HMC. The HMC information that is :
: returned is the same for all partitions of a physical machine. A :
: prefix is included at the beginning of the string. :

: For example, an HMC information string can look like this: :
: :
: {HMC}:HmcStat=1;HscName=7310C05*10A8C9A;HscHostName=w1212b;HscIPAddr :

SLIC V6R1M0 / XPF V6R1M0
SLIC V6R1M1 / XPF V6R1M0
SLIC V7R1M0 / XPF V7R1M0

Note: The minimum SLIC / XPF release required to install these tools/utilities is V5R4M0 / V5R4M0, respectively.

The main difference between DSPHMCINF and DSPSMDTA is that the first uses a machine instruction (available since SLIC V5R3M0) that only recognizes HMCs, while the second uses an updated machine instruction (available since SLIC V6R1M0) which recognizes HMCs, SDMCs, IVMs and VPMs.
