Resource names

Covers how to display and change resource names.

Communications lines, I/O processors, and devices are system resources. All system resources are identified by a resource name. To list the system resources, or display and change resource names:

See Hardware Service Manager.
Enter the resources command:
- WRKHDWRSC

During an IPL, all powered-on resources that do not have a name are assigned a name. The Licensed Internal Code assigns the name according to the order in which the resource reports to the system. The resource name is used for identification (by the Licensed Internal Code) during the next IPL, on displays, in printouts, and during system configuration.

Note: Many system resources are identified by both logical and packaging resource names. The logical and packaging hardware resources have different resource names.

Use the following tables to identify the logical and packaging system resources. For more information on system resources, see Hardware Service Manager and Product Activity Log.

Table 1. Logical resource naming formats
Name	Description	Example
A	Disk (device)	A1
BC	Bus controller	BC01
BCC	Bus controller (expansion adapter)	BCC01
BD	Bus extender driver	BD01
BR	Bus extender receiver	BR01
BUS	Bus	BUS01
CC	Communications IOP	CC01
CEC	System (logical)***	CEC01
CMB	Multiple Function IOP	CMB01
CTL	Workstation I/O adapter	CTL01
DC	Storage controller (disk, tape, diskette, optical)	DC01
ERR	Inoperative resource**	ERR01
I	Diskette	I1
LIN	Communications IOA	LIN01
LINE	Communications port	CMN01
MP	Main (system) processor	MP01
MS	Main storage card	MS01
OPT	Optical drive	OPT01
PN	Control panel	PN01
SI	Storage IOP	SI01
SP	Service processor	SP01
T	Tape device (external)	T1
TC	Tape device (internal)	TC
UNK	Unknown resource*	UNK0001
WS	Workstation I/O processor	WS01
See Note	Printer (device)	P1
See Note	Workstation (device)	W1
Note: Names for displays and printers are defined by the user as any two characters. `` An unknown resource (UNK) is one that is assigned to an I/O processor that is not operational, or to a device that the operating system does not recognize. `` An inoperative resource (ERR) is one that is not operational. Full vital product data might not be provided. `**` A system resource (CEC) is a collection of all logical resources that are attached to the processor. It also indicates the type, model, and serial number of the system.

Table 2. Packaging resource naming formats
Name	Description	Example
C	Card	C01
CE	Card enclosure (rack-mounted)	CE01
DE	Device enclosure (rack-mounted)	DE01
EE	Card enclosure (enclosure-mounted)	EE01
EMD	Device (enclosure-mounted)	EMD01
EMP	Control panel (enclosure-mounted)	EMP01
FR	Frame	FR01
SD	Stand-alone device	SD001
SYS	System (packaging)*	SYS01

* A system resource (SYS) is a collection of all packaging resources that are contained within, or attached to the system unit.
