Case 1. Easy display the parameters of the current disk configuration

Case 2. Easy create, change, delete  the parameters of the currently

created work disk configuration

     2.1. Create (copy) new I/O definition file

     2.2. Change I/O disk configuration data

     2.3. Delete I/O definition file if in error

Case3. How to build IODF  production configuration using ISPF/HCD

Case 4. How to prepare IPL with the new IODF configuration

     4.1. Create library LOAD member

     4.2. IPL  from production LPAR   with library LOAD member

 

The  4 examples bellow  of frequently  occurring cases  with production  IODF (Input Output Definition File) configuration of LPAR  using HCD (Hardware Configuration Definition) of TSO/ISPF are concerning the production LPAR BC2A of IBM/ZOS. The  descriptions  of the  cases bellow  explain how to: display  the old  work configuration IODF38, create a new IODF39 (by copy of old one), change device parameters and  delete (if IODF is wrong and require to create another) are followed by production IODF39  building  and   IPL prepare (to copy the old LOAD38 and to create new member SYS1.IPLPARM(LOAD39). The changes refer to disk volume  addresses  163A, … changing the Device Definition  parameter OFFLINE from YES to NO (or from NO to YES), so that the device 163A after IPL of  LPAR BC2A to be in the desired status – offline or online. This is necessary if two or more LPARs have access to all (common)  disk volume addresses  with duplicated volume names  in one environment and they should be separated.

 

           Case 1. Easy display the parameters of the current disk configuration

(in  production  LPAR using HCD of TSO/ISPF)

 

Display1: TSO/ISPF – sd.log – display the name of the current disk configuration if it is lost/forgotten

(Use MVS  command  to see     the name of the current disk configuration –  SYS1.IODF38)

/D   IOS,CONFIG

IOS506I 12.27.59 I/O CONFIG DATA 661

ACTIVE IODF DATA SET = SYS1.IODF38

CONFIGURATION ID = BC1B           EDT ID = 35

Display2:  TSO/ISPF – HC (HCD      – Hardware Configuration Definition)  –  display the parameters of the current disk configuration if no IODF source is available

(Use TSO/ISPF  HC menu  to display the parameters of the current disk configuration – I/O devices)

From this case it is clear that the disk volume with address 163A will be in status offline after  IPL.

The same display could be done for  Control units ,  Processors, Switches, Operating system configurations.

 

          Case 2. Easy create, change, delete  the parameters of the currently created work disk configuration

Use sys1.iodf39.work  on  production LPAR:

The sequence  is the  following:

– Copy new I/O definition file (create sys1.iodf39) using the currently accessed IODF38  into another data set (2.1).

– Change I/O definition file description  (sys1.iodf39.work) (2.2)

 -Delete I/O definition file –  if last sys1.iodf39.work  is in error (2.3)

               2.1. Create (copy) new I/O definition file

Use sys1.iodf39.work  on  production LPAR using HCD of TSO/ISPF as follows:

-HC

I/O definition file . . . ‘SYS1.IODF38.work’  – (Enter)

6.  Maintain I/O definition files (I/O definition file . . . ‘SYS1.IODF38.WORK’ – the old  IODF to be used)   (choose 6)

– 2_       1.  Delete I/O definition file              (choose 2)

              2.  Copy I/O definition file               

3.  Change I/O definition file description

4.  View I/O definition file information

5.  Export I/O definition file

–            Source IODF name . . . ‘SYS1.IODF38.WORK’ –  old

Target IODF name . . .  ‘SYS1.IODF39.WORK’  –  new (enter ‘SYS1.IODF39.WORK’ )

Activity logging . . . Yes                   (Enter Y)

The specified target file does not exist.  To create a new

file, specify the following values.

Activity logging . . . . Yes    (Yes or No)                 (Enter Y)

 

Copy request confirmed  .  1  / Yes/   (Enter 1 for Yes)

IODF SYS1.IODF38.WORK copied to IODF SYS1.IODF39.WORK.

After copy – these files are created: p.3.4 – sys1.iodf39.work

SYS1.IODF39.WORK                                                          BC2MCC

SYS1.IODF39.WORK.ACTLOG          Browsed               BC2MCC

SYS1.IODF39.WORK.CLUSTER          *VSAM*

                2.2. Change I/O disk configuration data
