Note. For Integrity NonStop NS14000 and NS1000 servers, Fibre Channel disks are
connected to IOAMs or VIO enclosures located in group 100. For more information, see
the NonStop NSxxxx Hardware Installation Manual for your Integrity NonStop NS14000 or
NS1000 server, or the Versatile I/O (VIO) Manual.
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 NSxxxx Hardware Installation Manual for
your Integrity NonStop NS16000, NS14000, or NS1000 server. 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.
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
