Starting the System
Starting the System
Starting a system involves loading the NonStop operating system into the memory of
each processor in the server. Use the OSM or TSM Low-Level Link to start a system
by either:
•
Using the System Startup dialog box is the normal method for most circumstances,
if you are performing a system load from the system disks located in slots 1.1.11
and 1.1.12.
•
Using the Load Processor-n From Disk dialog box to perform a system load from a
specified disk along a specified path to a specific processor is a method that is
used only in certain circumstances. For example:
°
If you are performing a system load from system disks that are located in any
slots other than slots 1.1.11 and 1.1.12.
°
If you need to perform processor dumps for an entire system or for the
processors in the group 01 system enclosure.
The System Startup Dialog Box
You use the System Startup dialog box to load the operating system from disk into the
memory of one processor. The remaining processors in the server are then reloaded.
If the system load fails along one load path, another load path is tried until the system
load is successful. There are eight possible load paths. This table describes the order
in which the load paths are tried:
During system load, two startup event stream windows and two startup TACL windows
are automatically launched on the system console configured to receive them.
Messages indicate the progress and completion of the system load (or device load)
and the reload of any processors configured in the CIIN file to start. When the system
load of the first processor is complete and the remaining processors are primed for
reload, the System Status box on the System Startup dialog box displays a “System
Startup Complete” message. The Processor Status dialog box shows the status for the
