System Load Using the TSM or OSM Low-Level Link
System Load Using the TSM or OSM
Low-Level Link
The operating system is loaded from disk into the memory of one processor. (This
operation is sometimes also 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. If necessary, log on to the Low-Level Link.
2. Start the system by clicking Start System.
The System Startup dialog box appears.
3. In the SYSnn text box, enter the number of the system subvolume containing the
version of the operating system that you want to load.
The number of the SYSnn last used to start the system is displayed as the default.
Enter the correct two-digit number to load the new version of software stored in the
SYSnn subvolume on the system disk.
4. Under Configuration File, select Current (CONFIG).
Current (CONFIG) is the default configuration and represents the last running
configuration.
5. Verify that the CIIN disabled option is not selected.
6. Click Start system.
During system load, two startup event stream windows and two startup TACL
windows are automatically launched on the system console configured to receive
them.
Note. The System Startup dialog box requires that the primary and mirror system disks
($SYSTEM) are installed in Group 01, Module 01, slots 11 and 12. If the system load fails
along one load path, another load path is tried until the system load is successful. To start
your system with a system disk in disk slots other than 11 and 12, use the Processor
Status dialog box, Load action, to access the Load Processor-n from Disk dialog box. This
dialog box allows you to type 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.
