HP NonStop NS manual Specified device, Backup processor number and PIN of the specified device

Determining Your System Configuration	Using SCF to Display Subsystem Configuration
	Information

The columns in Example 2-1 mean:

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

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 on page 2-7.

Table 2-1. Key Subsystems and Their Logical Device Names and Device Types

Subsystem Name	Logical Name	Device Type	Description
TCP/IP	$ZTCO	48	Transmission Control
			Protocol/Internet Protocol
			(TCP/IP)
Kernel	$ZZKRN	66	NonStop Kernel operating
			system
Storage	$ZZSTO	Disk: 3	All storage devices; for
		Tape: 4	example, disk and tape
		Open SCSI: 8
		SMF pool: 25
		SMF monitor: 52
		$ZZSTO: 65
		$ZSLM: 67
SLSA	$ZZLAN	43	All ServerNet LAN
			Systems Access (SLSA)
			connection and facilities
WAN	$ZZWAN	50	All wide area network
			(WAN) connections

Also, in Example 2-1 on page 2-7, 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.
