NonStop NS-Series Operations Guide (H06.12+)

12. For each Group 1nn, check that module 2 and module 3 are displayed.
13. If any of these components are not yet displayed, wait before you start the system.
14. After the system is powered on, you must wait 5 minutes before starting the system.
15. You can now start your system as described in “Starting a System” (page 158).
Starting a System
Use the OSM Low-Level Link to start a system. Starting a system includes a system load from
disk into the memory of one processor; followed by the reload of the remaining processors.
Loading the System
Perform a system load to load the NonStop operating system.
Alerts
• All processors in the system must be in a halted state before you perform a system load.
• To perform processor dumps during a system load, see the considerations in “System Load
to a Specific Processor” (page 158).
Normal System Load
Normally, you initiate the system load as described in “Performing a System Load ” (page 161).
When you choose this method:
• Processor 0 or 1 is loaded. See “System Load Paths for a Normal System Load” (page 159).
• The remaining processors are primed for reload.
• Two startup event stream windows and two startup TACL windows are automatically
launched on the system console configured to receive them.
• The CIIN function is enabled by default. See “CIIN File” (page 176).
System Load to a Specific Processor
Alternately, you can perform a system load from a specified processor. When you load the system
from a specified logical processor:
• The other logical processors are not primed automatically.
• Because the processors not being loaded are not primed, you can perform processor dumps,
if necessary. If you need to dump processors, refer to Section 9, Processors and Components:
Monitoring and Recovery.
— Do not prime or reset all the processor elements in a logical processor until after the
memory dump.
— Disable the CIIN file to prevent any processors configured to reload in that file from
being reloaded. The startup event stream windows and Startup TACL windows are
not launched automatically when the CIIN file is disabled. See CIIN File on page 16-6.
• The Processor Element Dump Setting option becomes available in the System Load dialog
box. For more information about this option, see Section 9, Processors and Components:
Monitoring and Recovery.
• You must initiate the load action as described in “Performing a System Load From a Specific
Processor” (page 162).
System Load Disks
An Integrity NonStop NS-series system can contain multiple system disk pairs in different
locations. Use the System Load dialog box to select which system disk to load from. You select
the system disk from the Configuration drop-down menu. The system load disk you choose
must be in the configured location, properly configured as a system disk, and contain the software
