Each NonStop NS2400 series system uses “Default Naming Conventions” (page 168) and ships
with the following default startup characteristics:
$SYSTEM disks residing in either SAS disk enclosures:
SAS and SAS CG Disk Enclosures
• Systems with only two Storage CLIM/CLIM CGs and two SAS/SAS CG disk enclosures with
the disks in these locations:

• Configured system load paths
• Enabled command interpreter input (CIIN) function
If the automatic system load is not successful, additional paths for loading are available in the boot
task. 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. These 16 paths are available
for loading and are listed in the order of their use by the system load task:
