NonStop Operations Guide for H-Series and J-Series RVUs

Table 1 gives the names of some subsystems that are common to most NonStop NS-series systems
and are routinely monitored by operations. These subsystems appear in the LISTDEV output in
Example 1 (page 42).

Also, in Example 1 (page 42) 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 J-Series and 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 NonStop systems. The examples use the
SCF ASSUME command to make a given subsystem the current default object for gathering
information.
CIP Subsystem
The CIP subsystem supports CLIMs in NonStop BladeSystems and in NonStop NS-series systems
that support CLIMs. The CIP subsystem cannot be totally determined via SCF. Instead, use climconfig
via CLIMCMD, as described in “CIP Subsystem Configuration” (page 50).
