HMC/SDMC/FSM Scanner Overview – downloads system configuration, produces single Excel spreadsheet, contains configuration of servers and LPARs

HMC Scanner Overview


HMC Scanner is a Java program that uses SSH to connect to an HMC or SDMC or FSM, downloads the system configuration and produces a single Excel spreadsheet that contains the configuration of servers and LPARs. The result is a simple way to document configuration and to easily look at most important configuration parameters. In PureFlex environments, only Power Systems compute nodes are detected.
Information is organized in tabs

System summary: name, serial number, cores, memory, service processor IP for each server

LPAR Summary: list of all LPAR by serve with status, environment, version, processor mode

LPAR CPU: processor configuration of each LPAR

LPAR MEM: memory configuration of each LPAR

Physical Slots: list of all slots of each system with LPAR assignment, description, physical location and drc_index

Virtual Ethernet: network configuration of each virtual switch and each LPAR

Virtual SCSI: configuration of all virtual SCSI adapters, both client and server

VSCSI Map: devices mapped by each VIOS to partitions

Virtual Fibre: virtual fibre channel configuration of client and server with identification of physical adapter assigned

SW Cores: LPAR and virtual processor pool configuration matrix to compute the number of software licenses. Simulation of alternative scenarios is possible.

CPU Pool Usage: easy to read history of CPU usage of each system. Based on last 12 months of lslparutil data.

Sys RAM Usage: easy to read history of physical memory assignement to each LPAR. Based on last 12 months of lslparutil data.

LPAR CPU Usage: easy to read history of CPU usage of each LPAR. Based on last 12 months of lslparutil data.


The tool is constantly updated to match changes in tool syntax, to manage new data types and to add new features. If you have any problem or any suggestion to improve HMC Scanner, please send me a mail ( Since new features are mostly suggested by users, propose yours! Please always include the downloaded files to allow be proper debugging.

HMC Scanner is packaged in a single ZIP file available in the download section of this page. A sample report is included.

nmon Analyser Version 3.4 = Just Released, Get Your Copy Today

Stephen Atkins (the Guru behind the nmon Analyser) has released a new version – two days ago.  This includes loads of improvements and some new features.  Best of all – less problems running on newer Excel releases (it works around inconsistencies with the Microsoft API).



I have always said that at least 50% of the popularity of my nmon is down to the excellent Analyser graphs. Very few people regularly see the online screen view.




Thanks again Steve, for all your many hours of hard work in your personal time on the behalf of the tens of thousands of nmon users.


  Download the new nmon Analyser version today from the nmon Analyser web page
or remember this URL




  Also note in the ZIP file there is the updated nmon Analyser documentation and answers to many common questions.


  If I get asked one more time: “What is a Weighted Average?”
  I might explode!    RTFM = Read The Flaming Manual.




 I ripped the below from that web page, to wet your appetite:




Version 3.4


  • Improved support for Excel 2007 and 2010

  • Support for 64-bit Windows

  • Ability to specify time values instead of interval numbers

  • Wildcard support in LIST

  • Limit the overall number of CPU, PhysicalCPU and SharedCPU sheets generated

  • Add graphs for the PCPU and SCPU sheets

  • Correct handling of the DISKRXFER sheet

  • Fix a bug with the MERGE option

  • Automatically include CPU_SUMM, DISK_SUMM and SYS_SUMM in LIST

NOTE:  V3.4 is designed for use with topas/nmon but will work with most older versions.   In case of problems analysing older files, try using V3.2.7
