  [CHPID OFFLINE DUE TO THE FOLLOWING REASON(S)]
     [SWITCH INITIATED RECONFIGURATION FOR CHANNEL PORT]
     [HMC REPAIR AND VERIFY]

where:

CHP=nn IS OFFLINE

The channel path is offline.

nn

The channel path for which status was requested.

CHPID OFFLINE DUE TO THE FOLLOWING REASON(S)

SWITCH INITIATED RECONFIGURATION FOR CHANNEL PORT

Channel is offline due to port decommissioning.

HMC REPAIR AND VERIFY

Channel is offline due to HMC repair and verify processing.

Or:

CHP=nn DOES NOT EXIST

The channel path does not exist.

nn

The channel path for which status was requested.

Or:

CHP=nn IS PART OF ANOTHER CONFIGURATION

The cause of issuing this reason is one of the following:

• The channel path is configured to another logical partition.
• The channel path is in single channel service (SCS) mode; that is, the channel path configured offline and placed in a diagnostic mode. While in SCS mode, the channel path cannot be configured online, even though it appears to be physically accessible.
• The channel path is not defined in the current I/O configuration.
• The sysplex name found by using the D XCF command does not match DCM IOCLUSTER name in IODF.

A reconfiguration display request (a DISPLAY M=CHP(chp) command) asked the system to display the status of a channel path and the devices connected to it. In the message text:

CHPID nn

A channel path (X'00' through X'FF').

TYPE=tt

tt is the channel path type.

DESC=description

Full description of the channel path type tt. For a complete list of channel path types, please see the section on message IEE174I Channel Path Type Status.

dev

The first 3 digits (or 4 digits, if multiple subchannel sets have been defined) of the device number. The last digit is indicated by the row of hexadecimal digits above the corresponding status positions.

ssss

If the channel path is switch-attached, then this is the switch device number. Otherwise, it is ‘NONE’.

ss

If the processor is cascade-capable and the channel path is native FICON® and switch-attached, then this is the logical switch number.

tttttt.mmm.nnn.pp.ssssssssssss

If the processor is cascade-capable and the channel path is native FICON, then this is the node descriptor of the device to which the channel is attached. These descriptors are made up of the following:

ttttt

Type number of the device.

mmm

The model number of the device.

nnn

The manufacturer identification code.

pp

The plant of manufacture number.

ssssssssssss

The sequence number, unique device number.

cccc

Physical channel identifier associated with the channel, if any.

facility1, facility2,...

A list of facilities supported by the channel. The following facilities may be displayed:

ZHPF

Indicates that High Performance FICON for System z (zHPF) facility is supported by the channel.

IEDN BRIDGED

Indicates that this CHPID provides connectivity to the IEDN via a bridge function.

attribute1, attribute2,...

A list of attributes supported by the channel. The following attributes may be displayed:

MFS(xxKB)

Displays the maximum frame size for an IQD CHPID. xx = 16; 24; 40; or 64.

type

Node type (See ndetype in IXLYNDE).

mfg

Node manufacturer ID (See ndemfg in IXLYNDE).

plant

Node manufacturer plant ID (See ndeplant in IXLYNDE).

sequence

Node sequence number (See ndesequence in IXLYNDE).

partition

Node LPAR partition number (See ndepartition in IXLYNDE).

side

The node PP/SI mode indicator and configuration code from the IXLYNDE are used to determine the value for side. Value and meaning are:

• SIDE: 0 means the coupling facility is on SIDE 0 of a partitionable CPC.
• SIDE: 1 means the coupling facility is on SIDE 1 of a partitionable CPC.
• blank means the coupling facility is in a non-partitionable CPC.

cpcid

Node Central Processor Complex (CPC) ID (See ndecpcid in IXLYNDE).

cuid

Control unit number of the coupling facility.

cfname

Name of the coupling facility from the CFRM active policy.

chpid / pchid

CHPID and/or PCHID for the coupling facility sender

phystatus

One of the following:

ONLINE

The path, chpid to the coupling facility cfname is physically available for use. The chpid is configured online and is operating.

ONLINE – DEGRADED

The path chpid to the coupling facility cfname is physically available for use. The chpid is configured online and is operating, but at a reduced capacity.

OFFLINE

The path, chpid to the coupling facility cfname is configured offline.

MISCABLED

The path, chpid to the coupling facility cfname is not connected to the correct facility.

NOT OPERATIONAL

• When displayed under SENDER PATH header, it indicates that the path chpid, to the coupling facility cfname, is not operational.
• When displayed under COUPLING FACILITY DEVICE header, it indicates that the coupling facility subchannel subchannel, to the coupling facility cfname, is not operational.

NOT IN CONFIGURATION

The path, chpid to the coupling facility cfname is defined to a control unit that is accessible by this partition. However, the chpid is not accessible by the partition (not in the access list nor the candidate list for this partition). The partition cannot access this chpid.

FACILITY PAUSED

The path, chpid to the coupling facility cfname is not operational. The most recent path validation operation attempted for this path received a facility paused status condition.

PATH NOT AVAILABLE

The path, chpid to the coupling facility cfname is not operational. The most recent path validation operation attempted for this path received a path not available status condition.

logstatus

One of the following:

ONLINE

The path chpid to the coupling facility cfname is logically online.

OFFLINE

The path sender chpid to the coupling facility cfname is logically offline.

chtype

One of the following:

CFS

The channel path type description of path chpid is Coupling Facility Sender.

totdev

Number of coupling facility subchannels that have been defined for this system.

usedev

Number of coupling facility subchannels that are currently being used by this system to execute requests to the coupling facility. This is equal to the number of concurrent operations that can be initiated to this coupling facility minus any subchannels that are not being used because of subchannel tuning actions.

nusedev

Number of coupling facility subchannels that are eligible to be used but are not currently being used by this system to execute requests to the coupling facility. This is equal to the number of subchannels that have been taken out of the pool of usable subchannels by subchannel tuning actions. This count may temporarily include some number of subchannels when a re-adjusting of the IN USE subchannel count is in progress as a result of configuration actions against CF Links for this facility.
