RELOAD Program (Super-Group Only)
lines, no controller ownership switch takes place. For these controllers,
problems can arise if an automatic ownership switch occurs during data
transmission. For other types of controllers (such as those for disks, tape
drives, card readers, and nonserial printers), a controller ownership switch
occurs if the reloaded processor was configured as the primary processor for
the controller.

The procedures for dumping an entire system that is frozen are described in the
NonStop S-Series Operations Guide or the NonStop NS-Series Operations Guide.
Examples
1. To reload processor 1 using the currently selected bus and to prevent switches in
device ownership, enter:
14> RELOAD 1, NOSWITCH
2. This G-series example uses the Y bus and the alternate operating system image in
the file $DATA.SYS02.OSIMAGE to reload processors 2, 4, 5, 6, and 7. The same
command then reloads all other downed CPUs using the default operating system
image and the currently selected bus:
15> RELOAD (2, 4-7) , $DATA.SYS02.OSIMAGE , 1; *
3. These H-series examples demonstrate use of the OMITSLICE option.
The first command uses a mutiple cpu-set specification, reloading all processor
elements belonging to logical processor 2 with the exception of the PE on slice A,
and the command continues to a second cpu-set specification to reload all PEs
belonging to processor 3.
Caution. For NonStop VLX systems, when using RELOAD in the CIIN file, you should not
use the PRIME option for two reasons: first, the processors are primed automatically in a
system cold load. Second, if you are reloading a single processor, the PRIME option in the
CIIN file causes any other failed processors to come up, thereby erasing their memory
contents; you are then unable to dump these processors to analyze the failure.
Note. When using the CIIN file, you should include in it only those necessary commands
that are restricted to super-group use, such as SETTIME or ADDDSTTRANSITION, and
perhaps a command to start a TACL process. Any other commands can be put into
system startup files. In particular, you should not put commands to start application
processes in the CIIN file, as they can cause CPU halts or system freezes in the event of
application malfunction.
