ZOS IOCDS build or change using HCD of ISPF
CONTENTS:
1. Activate or process configuration data
5. Confirm WRITE TO LEVEL A0 IOCDS
If you have to build an IOCDS (Input Output Control Data Set) using a new created production IODF (Input Output Definition File) configuration file an easy way exists with the HCD /Hardware Configuration Definition/ function of TSO/ISPF. This new IOCDS is used at POR (Power Off Reset) time to make the new configuration data known to z/OS. After entering HC of ISPF menu you have to specify the name of the I/O definition file . . . ( ‘SYS1.IODF48′ ) to be used and continue with Build IOCDS function. Then you have to perform some Actions on selected IOCDS configuration(A0, A1, A2..) – Update IOCDS and writing/rename the title and date of the changed configuration. A job is generated “CRIOCDS JOB07466 “ that is submitted, but not started. On syslog (sd.log) you have to answer/ REPLY ’YES’ for the job “CRIOCDS” to WRITE TO LEVEL A0 IOCDS or A1 IOCDS which is choosen to be replaced (“Disable write protection” for this IOCDS must be activated from HMC/Hardware Management Console/).
The following steps bellow describe the operations in detail:
1. Activate or process configuration data
After starting HC of TSO/ISPF menu go to following sequence:
- 2. Activate or process configuration data (choose 2)
For options 1 to 5, specify the name of the existing IODF to be used.
I/O definition file . . . ‘SYS1.IODF48′ – Enter
2. Build IOCDS
- 2. Build IOCDS (choose 2)
/ Proc. ID Type Model Mode Serial-# Description - Enter
- / BC1B 2066 001 LPAR (enter /)
Processor ID . . : BC1B
… Last IOCDS A0 to Update …..
/ IOCDS Name Format Date Time
- / A0 (enter / if choose A0)
_ A1
_ A2
_ A3 – Enter
- Actions on selected IOCDSs
3. Update IOCDS
1_ Update IOCDS . . . . . . . . . . (choose 1 _ u)
IODF name . . . . . . . . . : ‘SYS1.IODF48′
Processor ID . . . . . . . : BC1B IOCDS : A0
Title1 . z800io48
Title2 : SYS1.IODF48 – 2009-02-05 14:27
Dualwrite . . . . . . . . . . . . . . . No (Yes or No)
Switch IOCDS for next POR . . . . . . No (Yes or No)
Write IOCDS in preparation of upgrade No (Yes or No) - Enter
4. CRIOCDS JOB submitted
- Job statement information to fill up and Enter
//CRIOCDS JOB (9999),MSGLEVEL=(1,1),MSGCLASS=X,TIME=1440,CLASS=B
//*
IKJ56250I JOB CRIOCDS(JOB07841) SUBMITTED

**********
Job CRIOCDS JOB07466 was submitted, but not started.
To leave – press F3
/Leave HC dialog – Job continue/
//CRIOCDS JOB (9999),MSGLEVEL=(1,1),MSGCLASS=X,TIME=1440,CLASS=B

5. Confirm WRITE TO LEVEL A0 IOCDS
The same for // IPARM=’(IOCDS,A1,BC1B,I)’,
*0003 IYP050D SHOULD CRIOCDS WRITE TO LEVEL A0 IOCDS/or A1 IOCDS? REPLY ‘YES’, ‘NO’ OR ‘CANCEL’
Before answer to write on A0 you should activate “Disable write protection” for this IOCDS from HMC/Hardware Management Console/.
/3,yes – Enter from sd.log of BC2A to confirm WRITE TO LEVEL A0 IOCDS.
IYP057I IOCP JOB CRIOCDS SUCCESSFUL. LEVEL A0/or A1 IOCDS REPLACED.
I CBDA674I IOCP successfully completed for A0.BC1B or A1.BC1B.
If verified via HMC /Hardware Management Console/ – operations, A0 or A1 I/O configuration is OK according SYS1.IODF48 contents.
