nn

A channel path (X'00' through X'FF' ) to the device. Under each nn is Y or N indicating whether the corresponding condition is true or not.

DEST LINK ADDRESS la

A 1-byte or 2-byte address of a control unit that is used to access the I/O device associated with the specified channel path. If 1 byte, it is the link address. If 2 bytes, the first byte is the switch address (domain) and the second byte is the destination port address (area). This information will only be displayed when the cascade facility is available.

ENTRY LINK ADDRESS la

A 1-byte or 2-byte physical link address of the channel path to the entry switch. If 1 byte, it is the link address. If 2 bytes, the first byte is the switch address (domain) and the second byte is the entry port address (area). This information will only be displayed when the cascade facility is available.

CHP PHYSICALLY ONLINE Y|N

The specified channel path is (Y) or is not (N) configured online to the hardware.

PATH VALIDATED Y|N

The I/O check of the paths to a device was successful (Y) or has failed (N).

MANAGED Y|N

The channel path is (Y) or is not (N) defined as managed. This line will be displayed only for a managed subsystem.

ZHPF-CHPID Y|N

The channel path supports (Y) or does not support (N) the High Performance FICON for System z (zHPF) facility.

ZHPF-CU INTERFACE Y|N

The control unit interface supports (Y) or does not support (N) the High Performance FICON for System z (zHPF) facility.

MAXIMUM MANAGED CHPID(S) ALLOWED=n

The maximum number of managed chips that can be used by the control unit.

DESTINATION CU LOGICAL ADDRESS=da

The logical link address of a control unit that is used to access the I/O device associated with the specified channel paths.

CCCC

The control unit that was specified.

CU ND

Node descriptor of the attached subsystem.

CU NED

Node-element descriptor

TOKEN NED

Node-element descriptor that was most recently obtained from the control unit.

FUNCTIONS ENABLED=functions

Displays the functions enabled for the control unit. The following functions may be displayed:

ZHPF

Indicates that High Performance FICON for System z (zHPF) facility is enabled for use.

CONTROL UNIT IS INELIGIBLE FOR DCM FOR THE FOLLOWING REASONS

If the control unit is a managed control unit, the control unit is ineligible for Dynamic Channel-path Management (DCM).

rsntext can be one or more of the following:

UNABLE TO RETRIEVE CONTROL UNIT NODE DESCRIPTOR

The node descriptor cannot be retrieved for the control unit

UNABLE TO RETRIEVE INFORMATION FROM CHANNEL SUBSYSTEM

Configuration information such as the list of channel paths and the maximum number of managed CHPIDs cannot be obtained from the channel subsystem for this control unit.

A DEVICE/CHPID MISMATCH EXISTS

The devices for this control unit have different sets of CHPIDs.

CONTROL UNIT NOT SUPPORTED BY DCM

This model of control unit is not supported by DCM.

UNABLE TO RETRIEVE NEIGHBOR NODE (SWITCH) INFORMATION

The node descriptor information for the switches connected to this control unit cannot be obtained.

CONTROL UNIT HAS A MIX OF ESCON/FCV AND FICON CHPIDS

The control unit has both online ESCON or FICON bridge (FCV) CHPIDs and online FICON CHPIDs.

CONTROL UNIT SHARES CHPIDS WITH MIXED CHPID CONTROL UNIT

The control unit shares CHPIDs directly or indirectly with another control unit that has both online ESCON or FICON bridge (FCV) CHPIDs and online FICON CHPIDs.

SENSEID I/O ERROR

A sense-id channel program, which is part of a set of channel programs used to obtain control unit interface information, encountered an I/O error.

SENSEID I/O RETURNED INCORRECT INFORMATION

A sense-id channel program returned incorrect information.

UNABLE TO RETRIEVE REQUIRED COMMAND CODES

A sense-id channel program did not contain the command codes required to continue.

READ NODE IDENTIFIER I/O ERROR

The read node identifier channel program that was used to retrieve the list of control unit interfaces failed.

CONTROL UNIT INTERFACE INFORMATION IS NOT VALID

The read node identifier channel program that was used to retrieve the list of control unit interfaces was successful, but the information returned was not valid.

INCONSISTENT MAXIMUM MANAGED CHPID COUNTS IN GROUP

The managed control units in the control unit group have different maximum managed CHPID counts. All managed control units in the group (control units with a non-zero maximum number of managed CHPIDs) must have the same value.

DEFINED DEVICES

dddd

A list of devices defined for the specified control unit are displayed.

DEFINED PAV ALIASES

aaaa

A list of PAV ALIASES defined for the specified control unit is displayed.

tttttt.mmm.nnn.pp.ssssssssssss.uuuu

These descriptors are made up of the following:

tttttt

Type number of the device.

mmm

Model number of the device.

nnn

Manufacturer identification code.

pp

Plant of manufacture number.

ssssssssssss

Sequence number, unique device number.

uuuu

Two-byte tag.
