Use this command to initialize MPIF path definition records (PDRs).
Requirements and Restrictions
- You can enter this command only when you are prompted by the TPF
system.
- You must perform an initial program load (IPL) for the TPF system after
you initialize the path definition records.
Format
- INIT
- initializes the processor unique path definition records (#PDREU) for this
processor with the correct record identification and record code check
bytes. The remainder of each data record is set to 0. You will
be prompted to replace data in keypoint E by using the ZMPIF KPE
command.
- ALL
- initializes all PDRs for all processors. If you do not specify this
parameter, only records that are not initialized for the processor on which
the command is entered are initialized.
- BYPASS
- does not initialize the path definition records and ends MPIF
restart.
Additional Information
- Online help information is available for this command. To display
the help information, enter ZMPIF PDR HELP.
- If you enter ZMPIF PDR INIT, the command only initializes
records that are not initialized for the processor on which it is
entered. To initialize all PDRs on all processors, enter ZMPIF PDR
INIT ALL.
