5. To write a new A0 configuration generated by HMC or TSO/JES JOB

Here some usefull HMC /Hardware Management Console/ ZOS I/O Mainframe configuration operations on OS 2 WARP of IBM NetVista/ Pentium 4 are described. First of all you have to Sign on OS 2 WARP. Then go to Start IBM Primary Support Element and from TASK LIST of operations choose the CPC Configuration. If you wish to see which I/O Configuration (IOCDS A0) is active, go to I/O Configuration function (A0/new (last created on 16.01.2010) – A3/old/+VSE/LPAR + D0/Diagnose configurations are listed) – you will see that A0 from 16.01.2010 is active. To operate with any I/O configuration (IOCDS), position the desired configuration and process within the TASK LIST. Different function options exist for the choosen I/O configuration (IOCDS).
You may write a new A0 configuration generated by HMC or TSO/JES JOB if “Disable write protection “ function option for the new configuration is activated. To view or edit the active A0 configuration you have to “Disable write protection”, “Disassemble data set” and then “Open source file”.
Very short rules are given for starting and stoping Mainframe when urgent actions are needed.
1. HMC started – sign in OS2/IBM WARP
- Start OS 2 WARP on IBM NetVista/ Pentium 4
- Sign on with:
SYSPROG
PASSWORD
or
SERVICE
SERVMODE
2. Start IBM Primary Support Element
- Position and mark CPC – then choose and mark Z800/7km or BACKZ800/Aksakov
- Position and mark – Single object operations to enter IBM Primary Support Element (using right mouse button and TASK LIST – or if necessary – GROUPS to change CPC/IMAGES
) .
3. From TASK LIST of operations in IBM Primary Support Element – choose CPC Configuration menu – then I/O Configuration function (A0/new(last created on 16.01.2010) – A3/old/+VSE/LPAR + D0/Diagnose configurations are listed) and position the desired configuration A0 ( A2 is production at 7KM – Z800IO08 from 12.01.2005) with name Z800IO48 from 05.02.2009.
If necessary activate/deactivate or load (IPL) I/O configuration from TASK LIST Daily – press Activate/Deactivate and from TASK LIST CPC Recovery – press Load.
4. Option functions of I/O configuration menu to process:
- Enable write protection – to protect the current IOCDS
- Disable write protection – to write the new IOCDS
- Copy Configuration – copy to a new configuration name (for save)
- Open source file - open the IOCDS file for browsing or editting
- Import source file – import the IOCDS file from the preliminary prepared diskette
- Export source file – export the IOCDS file to diskette
- Delete source file – delete the file if not to be used
- Build data – build the IOCDS after editing the source
- Disassemble data set – to view the current configuration – POR is necessary after that
- Print Disassembled data set – print he IOCDS
- Exit – end the operations
5. To write a new A0 configuration generated by HMC or TSO/JES JOB
Option functions:
- Disable write protection
6. To view or edit A0 configuration
Option functions:
- Disable write protection
- Disassemble data set (the current Production I/O Configuration is destroyed – require IPL)
- Open source file
7. Enable write protection on A0
Option functions:
- Enable write protection
8. IPL with the old A2 configuration after Item 6 or with POR if A0 should be used
9. Start/stop of MAINFRAME-7km /KBI – 15.10.2010 г /friday/ – 12 hours – without VSE/LPAR
- HMC started
- Position and mark CPC – then choose and mark BACKZ800/Aksakov
- Stop – Position and mark – Single object operations to enter IBM Primary Support Element (using right mouse button and TASK LIST – CPC recovery – GROUPS – choose - IMAGES) – mark POR (Power off reset) – enter – all active LPAR’s appear in red – confirm YES to POR – Choose I/O configuration (IOCDS) A0/without BC4A- VSE LPAR / – confirm to POR for restart - Wait 7 minutes to stop.
- Starting – press GROUPS – choose - IMAGES – mark all LPARs – using right mouse button and TASK LIST find ACTIVATE – press enter to activate all partitions – wait to finish – IPL with the new A0 configuration without LPAR BC4A ( VSE/LPAR).
