Run ZPHIRNM
This command causes the spooler to move from the active to the dormant state.
For more information on draining the spooler and recovery, see Section 1 in the
Spooler Utilities Reference Manual.
Run ZPHIRNM
Using PREVIEW Mode
You can do a preview run of ZPHIRNM to check that the target subvolumes (TSVs)
and associated map files are consistent. Running ZPHIRNM in PREVIEW mode
simulates the ZPHIRNM process without actually updating files or activating the
configuration. In PREVIEW mode, ZPHIRNM indicates whether or not TMF needs to
be up when running ZPHIRNM. See ZPHIRNM on page 10-4 for more information.
Run ZPHIRNM
1. At a TACL prompt, enter the following command from the DSM/SCM subvolume:
> RUN ZPHIRNM $vol.SYSnn
where:
•
$vol specifies the default current system load volume, usually $SYSTEM.
•
SYSnn specifies the SYSnn subvolume named previously in the backout
request. (See Submit a Backout Request on page 14-3, Step 3 on page 14-4,
which explains the entries in the Backout - Verify Request screen.)
For example:
> RUN ZPHIRNM $system.SYS00
2. When asked if you want to use a log file with the session, type Y and press Enter.
3. When prompted, type a file name for the log file, and press Enter.
4. ZPHIRNM issues the following message and begins processing:
Log file, <filename>, was successfully created.
Caution. Do not use the TACL STOP command to drain or stop the spooler. Also, do not
issue the TACL STOP command after you have issued the SPOOLCOM DRAIN command.
The control file can be corrupted during the next warmstart or rebuild.
