Table 2-1 gives the names of some subsystems that are common to most Integrity NonStop
NS-series systems and are routinely monitored by operations. These subsystems appear in the
LISTDEV output in Example 2-1 (page 40).

Also, in Example 2-1 (page 40) several disk drives and tape drives have been configured. You
can identify the subsystem that owns a device by looking up its device type in the SCF Reference
Manual for H-Series RVUs.
To display information about a particular device:
> SCF LISTDEV TYPE n
where n is a number for the device type. For example, if n is 3, the device type is disks. For the
\MS9 system, entering LISTDEV TYPE 3 would display information for $DATA6, $DATA5,
$DATA4, $DATA3, $DATA2, $DATA1, and $DATA.
To display information for a given subsystem:
> SCF LISTDEV subsysname
where subsysname is the logical name of a subsystem; for example, $ZZKRN for the Kernel
subsystem.
Displaying SCF Configuration Information for Subsystems
The following tables give some of the SCF commands that display configuration information for
objects controlled by subsystems that are common to most Integrity NonStop NS-series systems.
The examples use the SCF ASSUME command to make a given subsystem the current default
object for gathering information.
