In nearly all circumstances, items that are essential to system operations that must be
running at all times restart automatically if they are stopped for any reason while the
NonStop Kernel operating system is running.
Some OSM processes stop after executing a macro that runs during system load or
during the reload of processor 0 or 1. Those processes include $ZOLHI.
Optionally, you can also configure other processes such as the Expand subsystem
manager process, $ZEXP, and the Safeguard monitor process, $ZSMP, as generic
processes.

Recovery Operations for Processes

For recovery operations on generic processes, use the SCF interface to the Kernel
subsystem and specify the PROCESS object. These SCF commands are available for
controlling generic processes:
ABORT
START
Generic processes that are configured to be persistent usually do not require operator
intervention for recovery. In most circumstances, persistent generic processes restart
automatically.
For recovery operations on IOPs, refer to the WAN Subsystem Configuration and
Management Manual, the SWAN Concentrator and WAN Subsystem Troubleshooting
Guide, and the Expand Configuration and Management Manual.
For recovery operations on system processes, refer to the Guardian User's Guide.
