Loading the System
•
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.
•
A load from $SYSTEM attempts to load the system from a disk in group, module,
slot 11.1.11 of a NonStop S-series I/O enclosure, by default.
•
You can configure additional alternate system disks to load from. 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.
System Load Paths for a Normal System Load
16 paths are available for loading. Table 15-1 describes each load path in order of use.
The system load task attempts to use each path until the system load is successful or
all possible paths have been tried. If the system load fails along all paths, refer to
Troubleshooting and Recovery Operations on page 15-18.
