Backing Out If a Previous Configuration Does
Not Exist or If DSM/SCM Does Not Run
Task 1: Run ZPHIRNM
1. Run ZPHIRNM in PREVIEW mode:
> RUN ZPHIRNM [$
vol
.]SYS
nn
, FROM [$
vol
.]SYS
nn
, PREVIEW
[STRICT] [,
option
]...
If no arguments are entered, help text appears.
2. If the process generates errors, correct them and run ZPHIRNM in PREVIEW
mode again. If no errors occur, continue.
3. Run ZPHIRNM:
> RUN ZPHIRNM SYS
nn
, from SYS
nn
where SYS
nn
the same number for both in this command.
For example: If you first used DSM/SCM to apply SYS01 to a system running
SYS00 (not applied by DSM/SCM), you need to back out to SYS00:
> RUN ZPHIRNM [$
vol
.]SYS
01
, FROM [$
vol
.]SYS
01
Use SYS01 for both entries even though you are backing out to SYS00. Using the
same SYS
nn
after FROM is a special directive for DSM/SCM.
ZPHIRNM displays this prompt:
Do you want to use a log file with this session? (Y/N)
4. Type Y, and press Enter.
ZPHIRNM displays this prompt:
You may use any file for logging. If you request to use a
disk file that doesn’t exist, it will be created as an entry-
sequenced file.
Please enter a filename:
5. Enter a disk file name.
ZPHIRNM displays this message:
Log file,
filename
, was successfully created.
ZPHIRNM then renames the applied files. If ZPHIRNM notifies you of any errors,
correct them and run ZPHIRNM again.
Note. You can also use this procedure if you have to back out from your first DSM/SCM
configuration, and you performed your previous configuration activities using Install.
