Backup
• A SCSI-Load attempts to load the system from a disk in group, module, slot 11.1.11 of a
NonStop S-series I/O enclosure. See Table 7-1 (page 95).
• You can configure additional alternate system disks. To create an alternate system disk, see
the NonStop NS-Series Hardware Installation Guide. Then use OSM to make the disk available
in the Configuration Drop-down menu in the System Load dialog box. The alternative system
disks are displayed in the Attributes tab under the System object in the OSM Service
Connection and are also displayed in the OSM Low-Level Link System Load dialog box in
the Configuration shortcut menu.
Alerts
Before performing a system load:
• Before halting the processors, stop applications that are still running, including TMF.
NOTE: To stop TMF, at a TACL prompt, enter: 5> TMFCOM STOP TMF
The NonStop NS-Series Operations Guide contains detailed information on the best methods
for stopping applications, devices, and processes.
• Do not close the System Load Startup dialog box while startup is in progress. If you attempt
to close the dialog box, a message dialog box appears notifying you that the system startup
process will be stopped if you continue.
• If you stop a system startup before it has finished, the state of your system will be
unpredictable. You might need to perform another system startup to enable the system to
resume normal operation.
• If you must stop the system startup process, click Abort. (The abort process should take
effect within 30 seconds.)
• If you do not select a $SYSTEM volume, you must revive the mirrored disk.
• In the System Load dialog box, either select all four disk paths, or check that the selected
disk path is correct. If you do not select all four or select the incorrect disk path, the system
does not load properly.
• If you have problems performing a system load, see the NonStop NS-Series Operations Guide,
Chapter 15.
Halt the Processors
1. Log on to the OSM Low-Level Link.
2. On the toolbar, click Processor Status to display the Processor Status dialog box.
3. Under Processor Status, select all processors.
4. From the Processor Actions list, select Halt.
5. Click Perform action.
6. Click OK when asked “Are you sure you want to do Halts?”
7. When the Action Status box confirms that all processors have halted, close the Processor
Status dialog box.
Loading the System
If the automatic system load is not successful using one load path, the system load task attempts
to use another path and keeps trying until all possible paths have been used or the system load
is successful. Eight paths are available for loading.
