Using SCF to Determine Your System Configuration
The columns in Figure 2-14 mean:
Table 2-6 gives the names of some subsystems that are common to most NonStop
S-series systems and are routinely monitored by operations. These subsystems
appear in the LISTDEV output in Figure 2-14 on page 2-29.
In Table 2-6 the logical name for TCP/IP, $ZTCO, is not preconfigured by HP. The
name that is displayed on your system is the name that is configured for TCP/IP at
your site.
Also, in Figure 2-14 on page 2-29, several disk drives and tape drives have been
configured for \MS9. You can identify the subsystem that owns a device by looking up
its device type in the SCF Reference Manual for G-Series RVUs.
LDev The logical device number
Name The logical device name
PPID The primary processor number and process identification number (PIN)
of the specified device
BPID The backup processor number and PIN of the specified device
Type The device type and subtype
RSize The record size the device is configured for
Pri The priority level of the I/O process
Program The fully qualified name of the program file for the process
