Shared Storage Pool config dump command
I have been testing out the AIX libperfstat libraries new functions and got to the SSP ones. So I knock up this command to dump the config details that can be extracted. So with 128 lines of C code we have the new command - I have not seen a new VIOS SSP command that outputs this data yet so this is new details that I think would help you rebuild a SSP if you had an accident or disaster. Command line interface # ./nsspconf -h
Hint: [-v] [-h]

HMC 7063-CR1 software install (POWER8 based HMC)
This is part two covering the POWER8 based Hardware Management Console The first part was covering the installation on the new POWER8 based Hardware Management Console. You can find it here: AIXpert Blog on HMC_7063_CR1_hardware_install_POWER8_based_HMC First a small recap on what we covered at the end of Part 1 about the network ports. Below we can see the lower HMC has three network ports in use. The low HMC has VGA screen and USB keyboard and USB mouse. Two power supply cable from the HMC to two different Power Distribution...

HMC 7063-CR1 hardware install (POWER8 based HMC)
We at Advanced Technology Support, UK have been running the HMC based on POWER8 for 4 months but it was based on a proto-type HMC based on the S822LC Supermicro Stratton. T his week, our genuine official HMC's that use the POWER8 chips have arrived, so I thought I would via pictures show you what we did to get them installed. You can find the IBM KnowledgeCenter information here: https://www.ibm.com/support/knowledgecenter/POWER8/p8hai/p8hai_install7063_kickoff.htm This is part one covering the POWER8 based Hardware...

nmon to JSON plus new direct JSON monitor
By popular demand, I have been busy working on this in the background. As you know nmon is not my day job. nmon2json First , is a tool to take an nmon output file (.nmon which is a Comma Separated Value text file) and convert it into JSON format. JSON is the preferred format for many "new age" web 2.0 tools to ingest into a database and/or support dynamic graphing of the stats. JSON is a simple format but there are options for grouping stats. I would like your comments on that and what is the best... [More]

POWER8 Watts, Temp, SSP I/O & Server/LPAR stats from HMC REST API - Version 3
Ready for use. Please feedback success or problems. I will actively support you. See Download section. Objectives: In this version, we will extract the POWER8 energy stats (Watts electricity and Temperatures) in 34 lines of Python code using a new Python Module. The Shared Storage Pool I/O and Server = LPAR stats work the same way but as there is more stats take a little more code but works the same way. Output: Sample output for Energy stats - for SSP I/O and Server +LPAR performance stats fine the grapghs later on. Sample... [More]

Shared Storage Pool Stuck or Down? Don't Panic - Raise a PMR
I have a few customers and IBMers tell me their Shared Storage Pool (SSP) failed to come up after some major disaster like Total network outage Total SAN outage Total site unexpected electrical power outage They then fiddle about and eventually, like hours or even days later, send me email. All I can say is I am sorry to hear about their issue, that I don't have that problems and I have had my share of electricity cuts (ironically while testing the uninterruptible power supply!). But I can offer some advice . . . The... [More]

nmon for AIX detects LPM & DLPAR Changes
It seems that not many nmon users know that nmon for AIX will detect and show on-screen or save to the nmon file many AIX events. That is the problem about being the nmon designer and developer for so many years - it is called expert blindness. It is totally obvious to me until a respected nmon user asks a question to which my initial reaction is how can you not know the answer to that ! It can detect these among a number of other events and record them: Live partition Mobility (LPM) where you move a running Logical Partition... [More]
