BC9 INL

How do I create a BC9 INL from an existing system? by FICRI

How to create a BC9 INL from an existing system.

N.B. The created INL will contain ONLY the program units residing in the source BC9 system.

Prerequisites: An MD110 BC9 system, as complete as possible regarding program units and patches.

Assumptions:
1. The BC9 system contains subfile systems SYSSUBFS11 and SYSSUBFS21 only.
2. A new HDU is to be used as an initial load volume.

Before you do anything else start with a complete system dump to the original HDU:
DUSYI:DUMP=ALL;

If the dump was successful you can continue.

Uninstall the original HDU:
BLEQI:EQU=X-X-X-0;
FIMOE:SUBFS=SYSSUBFS11;
FIMOE:SUBFS=SYSSUBFS21;
IOSIE:NODE=SYSN,IODEV=SYSDISK1;

Switch off the original HDU.

Place the new HDU in a free position in the magazine.
Move the SCSI-cable from the original HDU to the new HDU. Don¦t forget to put the terminator plug in the other connector on the new HDU.

Install the new HDU:
Switch it on.
IOSII:NODE=SYSN,IODEV=SYSDISK1,SIPOS=3,SUBFS=SYSSUBFS11&SYSSUBFS21;
FICRI:SUBFS=SYSSUBFS11,SIZE=64;
FICRI:SUBFS=SYSSUBFS21,SIZE=64;
FIMOI:SUBFS=SYSSUBFS11;
FIMOI:SUBFS=SYSSUBFS21;
BLEQE:EQU=X-X-X-0;

Check that the initiation was successful:
IODDP;
FISCP:IODEV=SYSDISK1;

Make a system dump to the new HDU:
DUSYI:DUMP=ALL;

Check that the dump was successful.

Now it¦s time to make a dump in initial load format:
DUSII;

Check that the dump was successful.

There is now an INL besides REL1 and REL2 on the new HDU. The HDU is to be used for initial loading so the RELs have to be deleted otherwise an initial load will not start when you initiate a load from the new HDU. The system will then make a RELOAD.

Delete REL1 and REL2:
FIDIE:PATH=/SYSN/USR1/SES/DR/REL1,OPT=ALL;
FIDIE:PATH=/SYSN/USR2/SES/DR/REL2,OPT=ALL;

Uninstall the new HDU (HDU-INL) from the system:
BLEQI:EQU=X-X-X-0;
FIMOE:SUBFS=SYSSUBFS11;
FIMOE:SUBFS=SYSSUBFS21;
IOSIE:NODE=SYSN,IODEV=SYSDISK1;

Switch off the HDU-INL.

Reinstall the original HDU:
Move the SCSI-cable and terminator plug back to the original HDU and switch it on.

IOSII:NODE=SYSN,IODEV=SYSDISK1,SIPOS=3,SUBFS=SYSSUBFS11&SYSSUBFS21;

DO NOT USE THE FICRI COMMAND AT THIS POINT OR THE CONTENTS OF THE ORIGINAL HDU WILL BE ERASED!!!!!!

FIMOI:SUBFS=SYSSUBFS11;
FIMOI:SUBFS=SYSSUBFS21;
BLEQE:EQU=X-X-X-0;

Check that the initiation was successful:
IODDP;
FISCP:IODEV=SYSDISK1;


The procedure is now finished and you have an HDU that can be used as an INL volume.

How to make an initial load of an MD110 is a different story.

Good luck!
