G'day All,

If were to draw the architecture/device diagram for any mainframe system, where to start?!

One way is I can look at the IOCDS and start drawing from there, or use device related commands and start mapping devices to their CHPIDs thru switches (very time consuming may be).

Is there another more efficient way of doing it ?! Please help.

Also, what device related commands will be useful?! So far I have used the following...

/D M=CHP
/D M=DEV
/D M=DEV(ucb #) --- this one to find the entry ports at the switch
/D M=CHP(chpid) --- to find what paths are operations/defined
/D U,dev type,status,ucb #,number of devices - to validate the devices

I am referring to IOCDS and using above commands to put together our mainframe device architecture diagram. The process is time consuming, the IOCDS has information related to 6 LPARs!

Please suggest if there is an easier way, or if some more commands/tips would help me to do it faster?

Thanks

Out of interest, why do you need to do this? Is it going to be maintained? Why such detail? Have you checked with technical support/hardware people?

Yes ,it will be maintained and used for trainings. We have many factory mainframe systems where we build and packege software for our clients. For people who get trained to build z/OS packages this is one of the activities! icon_smile.gif

We are currently waiting for z\OS 2.1 and in preparation this is one of the activities. It is more for self learning and training others.

Do you really mean you are waiting for z/OS 2.1, no typos, you're going to get the new one?

Looking for a "jealousy" simley, can't find it.

In my experience someone installing the hardware/software has what you want (or a basis), but I guess in your case it may be you coming up with it... has no-one done this before? I don't know if there are any packages to do this. The diagrams I've seen are so jealously guarded because they took so long to put together, that I certainly wasn't allowed to take them to the canteen to have a look at over a cup of tea and a bun :-)

I remember reading somewhere an Ibm <something> about 2.1 delivery in September 2013.

but for the current question ...
what about searching The manuals to arrive to

http://publib.boulder.ibm.com/infocenter/zos/v1r12/index.jsp?topic=%2Fcom.ibm.zos.r12.cbdu100%2Fbuildio.htm

IOCDS reports ???

I wonder why people do not look at the manuals before asking icon_cool.gif
( I knew where to find the info,
but to confirm how simple would have been for the TS to get there himself I googled for IOCDS batch reports and I got the same link )

Yes, Bill. We are getting z/OS 2.1 as soon as it is available! We have just successfully tested and implemented 1.13 RSU1206 icon_smile.gif But I have not done any work related to this yet! I mostly do IMS and IMS products. I am preparing myself to be part of the team that will do z/OS 2.1. And, to be able to come up with architecture diagram is one of the tasks I am expected to do!

I now have a fair idea of reading IOCDS and using commands to start writing the architecture, I just wanted to check if someone has better/faster ideas!

Hi Enrico,

Sorry, if I made you think that I have not googled for the info first. I did lot of manual referring and googling. I also have started to put together the architecture diagram using IOCDS and commands. I am only here to find for inputs from people who must have done this kind of work a lot and they would have better methods than mine ! icon_smile.gif

I do have the IOCDS already, generated it using HCD option 2.2.

Do you have FDR on your system? If you do you can get virtually all ofthe info you need about your DASD from that using the VOLDATA reports. Everything from volsers, devtype,cuaa, controller ID and brand, channel address etc etc.

For Tape the SMSVMA reports can be quite useful but require some SMF extracts.

I've not used the HCD reports but I would have thought you could most things from those for the other devices

Thanks Pete.

My goal is to put together an architecture diagram showing our CPC details, CSS details, LPAR IDs, MIF IDs, CHPIDs, PCHIDs, ESCON and FICON connections, all the Control Units, devices and device addressess connected to those CUs (could be DASDs, TAPEs etc..), the switches/directors between the PCHIDs and CUs with their entry and exit ports, network connections....and so on...!! I know, the diagram would look very messy and confusing. But will help me understand various components of system z architecture...not in depth...but just enuf to feel comfortable as Sys Prog! icon_smile.gif

This is how I am doing it now...

/D M gives me CPC, LPAR and MIF details.

/D M=CHP to find out the active and defined CHPIDs.

Then I use /D M=CHP(chpid #) to verify the devices attached to those CHPIDs and the PCHID information.

The /D M=DEV(device #) gives me the CHPIDs, entry and exit ports of the switch and the control unit number.

I am using these commands along with IOCDS to map the devices and other components (very time consuming and confusing).

It would help, if someone can add more to the above method I am using (to simplify/correct it!).

the last post is just a useless repeat of the first one.

why do You stubbornly refuse to use the batch report facilities ( simpler ) ???

You could try using a REXX to issue the D M commands and use the OUTRAP function to capture the command responses and collate all the info into a file.

After that how you would format it into a diagram would depend on how you want it displayed and what sort of software you have to generate it. It could be done in Excel I suppose. Have one tab with the diagramatic view that draws info from other tab(s) where you have imported your collected data from the mainframe file.

Also if you're working for an FM/Oustsourcing firm then maybe you could ask them to stump up some money for a tool to do this if there is one.

the problem with the TS is that he stubbornly wants to stick to the Display approach ...

if he would take the time to look at the IOCD manuals he would see that there is also the possibility to have a graphical representation of the configuration

BTDTGTTS

but looks like we are wasting time giving good advices

Hi Enrico,

It is not stubbornness, you can call it 'limited exposure' ! icon_smile.gif I was just focussing on what little I know now and trying to build on it. When you mentioned about IOCDS reports earlier, I thought you are talking about generating IOCDS! From your recent post I see there are different reports getting generated for devices/connections/switches!

Thank You, I will give it a try now icon_smile.gif

Thank you, Pete.

I am using excel to put the diagram! Not good enuf in excel to convert data in one tab to a pictorial representation in another tab! icon_smile.gif I will give it a try though.

I may be able to get required data from the reports Enrico suggested and use them as input data to my excel to do the diagram!

As far as being able to spend money to obtain a tool, they might say "How about we let you go and use that money to get the tool?! " icon_smile.gif such are the times !!
