Privilege Class: B
Use QUERY CHPID to display the following:
v All devices with logical channel path yy installed
v Logical path status as it pertains to those devices (online, offline, or quiesced).
Use QUERY CHPID yy PCHID to display the physical channel identifier associated
with CHPID yy.
Use QUERY CHPID yy TYPE to display the channel path type of CHPID yy.
yy is the logical channel path whose device allocation information is requested.
The variable yy must be a 1- to 2-digit hexadecimal number between X'00' and
X'FF'.
PCHID
requests the display of the physical channel identifier associated with CHPID
yy.
Note: This parameter is valid only when your processor is capable of logical
channel-subsystem support.
TYpe
requests the display of the channel path type of CHPID yy.
1. The QUERY CHPID command shows all devices associated with a specific
logical channel path. For information about physical channel paths, use the
QUERY CHPIDS command. (See page 708.) For information about logical and
physical channel paths associated with a specific device, use the QUERY
PATHS command. (See page 918.)
2. If a device has never been initialized, its path information is not available and,
therefore, cannot be included in the command response.
3. Internal channel path types such as internal-queued-direct-communications
(IQD) channels and internal-coupling-peer (ICP) channels are not associated
with physical channel paths (PCHIDs).
To display all the devices on path 1A, enter:
query chpid 1a
