Perform a System Load
Perform a System Load
When you perform a system load, the operating system is loaded from disk into the
memory of one processor. (This operation is sometimes called a device load or cold
load.) All possible paths to processor 0 are tried; if these fail, all possible paths to
processor 1 are tried. The remaining processors are loaded by commands in the CIIN
file. The initial TACL process stops after executing the CIIN file.
1. Using the OSM Low-Level Link or TSM Low-Level Link Application, click Start
System.
The System Startup dialog box appears.
2. In the System Startup dialog box:
•
In the SYSnn box, enter the number of the system subvolume containing the
version of the operating system that you want to load. The value nn must be a
two-digit octal number in the range %00...%77.
•
In the Configuration File area, select Current (CONFIG).
•
Make sure that the CIIN disabled option is not selected.
3. Click Start System.
When the system load has successfully initiated (the operating system loaded into
the memory of processor 0 or processor 1), the System Status box in the System
Startup dialog box shows:
SYSTEM STARTUP COMPLETE, NSK RUNNING ON PROCESSOR n
Note. The number of the SYSnn last used to start the system appears as the default.
Type over it with a new two-digit number to change to a different version of software
stored in the SYSnn subvolume on the system disk.
Note. The System Startup dialog box requires the primary and mirror system disks
($SYSTEM) to be installed in Group 01, Module 01, slots 11 and 12. It first tries slot
1.1.11 and then 1.1.12. Starting with the G06.06 RVU, you can install the system disk
in any two disk slots in Group 01.
To start your system with a system disk in disk slots other than 11 and 12, you must
go through the Processor Status dialog box, Load action, to access the Load
Processor-n from Disk dialog box. This dialog box enables you to enter the group,
module, and slot number of the disk from which you want to load; it does not try
alternate paths or alternate disk slots. See the NonStop S-Series Operations Guide for
more information.
Caution. If you want to stop the system startup process, click Abort (the process takes effect
within 30 seconds). If you stop a system startup before it has finished, the state of your system
cannot be predicted. You might need to perform another system startup to enable the system
to resume normal operation.
Do not close the Start System dialog box; otherwise, your system will not load.
