RELOAD Program (Super-Group Only)
•
If your command repeats a processor number, RELOAD displays:
CPU n already specified
where n is the processor number you specified more than once in the RELOAD
command.
•
The alternate operating-system image file (in H-series, the OS FileSet) option:
°
Provides additional fault tolerance if the current file is unavailable.
°
Distributes paging activity.
The alternate operating-system image file (in H-series, the OS FileSet) you use
must be an exact duplicate of the file being used by the processor from which the
RELOAD command is issued. All processors must be loaded with identical
operating-system images. The alternate operating-system image file (in H-series,
the OS FileSet) option is not a substitute for cold loading the system. It cannot be
used to change the operating-system image.
If an alternate operating-system image file (in H-series, the OS FileSet) is
specified, that file continues to be used by the processor into which it is loaded.
Thus, different processors can be using identical files from various locations.
In addition, if an alternate operating-system image file (in H-series, the OS FileSet)
is specified, all the files in the reloader’s default SYSnn must be present in the
subvolume specified in the alternate fileset option of the RELOAD command.
•
G-series and D-series Only. RELOAD checks the operating-system image file to
ensure that it has the same timestamp as the operating-system image in the
processor doing the reload. If the timestamps do not match, and the volume is
already accessible (allowing the timestamp to be immediately checked), reloading
of the affected processors does not occur. If the volume is inaccessible, the
reloaded processor checks the timestamp and halts with a %4016 code if it does
not match.
•
You can use an IN file to enter RELOAD command parameters. The IN file can be
a disk file but not a terminal. An IN file can contain multiple lines as long as no
cpu-set is divided between lines. To start a RELOAD process using an IN file,
enter RELOAD with only the IN file-name specification. (For more information, see
the RUN[D|V] Command on page 8-156.)
•
When one of the two processors connected to a controller fails, the other
processor gains ownership of the controller. When a failed processor (or one that
has not been loaded) is reloaded:
°
If you specify NOSWITCH, no controller ownership switch takes place. The
processor that did not fail retains ownership.
°
If you omit NOSWITCH, controller ownership action depends on the type of
controller and whether the processor that was reloaded was configured during
system-image generation as the primary processor for the controller. For
controllers connected to terminals, serial printers, and data communication
