HP Integrity NonStop H-Series - Manual (Page 212)

NOTE: For some software revisions, you must leave certain applications running, such as TMF
or Safeguard. Running ZPHIRNM in PREVIEW mode displays a message if TMF must be running
to rename certain files. Consult the instructions for the RVU you are backing out to for any special
instructions to leave certain applications running.
Task 6: Run ZPHIRNM in Preview Mode
Running ZPHIRNM in PREVIEW mode simulates the ZPHIRNM process without updating files or
activating the configuration. For more information, refer to
“Run ZPHIRNM in Preview Mode”
(page 123) .
If the process generates errors, correct them and run ZPHIRNM in PREVIEW mode again. If no
errors occur, continue with
“Task 7: Rename Software Files Using ZPHIRNM” (page 212) .
Task 7: Rename Software Files Using ZPHIRNM
Running ZPHIRNM renames the files in the previous revision from their saved file names to their
actual file names.
CAUTION: If you decide to delete a logical target after performing a backout, check that the
entire backout process finishes, including receiving the snapshot at the host system.
Enter this command using the SYSnn for the configuration you are backing out to:
> RUN ZPHIRNM [$vol.]SYSnn , [ option,]...
For more details, see “Run ZPHIRNM” (page 124) .
ZPHIRNM must run without errors to complete the software activation. ZPHIRNM issues an EMS
message when it has successfully finished. If the new revision does not require a system generation
or system load, proceed to
“Task 9: Start TMF and Your Applications” (page 212) .
Task 8: Stop and Load the System
1. Stop the system by halting the processors. The method you use varies depending on the type
of system. For more information, refer to
“Stopping the System by Halting the Processors”
(page 127) .
2. Load the system. The method you use varies depending on the type of system. For more
information, refer to
“Loading the System” (page 128) . For NonStop S-series systems and
Integrity NonStop system, load the system using a saved system configuration.
Task 9: Start TMF and Your Applications
After you are back to your previous software configuration and system configuration, you can start
your applications, including TMF.
Backing Out in Special Circumstances
In these circumstances, backing out requires a different procedure:
• “Previous Configuration Does Not Exist or DSM/SCM Does Not Run” (page 213)
• “After Renaming the SYSnn” (page 213)
• “Backing Out to an Older Configuration” (page 214)
