QUERY VIRTUAL CHPID
Authorization
Privilege Class: G
Purpose
Use QUERY VIRTUAL CHPID to display the devices associated with a virtual CHPID number or the virtual CHPID type.
Operands
- CHPID
- yy is the logical channel path of the virtual CHPID whose device allocation information is requested. The variable yy must be a 1- to 2-digit hexadecimal number between X'00' and X'FF'.
- TYPE
- Display the CHPID type.
Responses
Response for Path Status:
PATH yy {ONLINE } TO DEVICES xxxx(1)
… xxxx(n)
PATH yy {OFFLINE} TO DEVICES zzzz(1)
… zzzz(n)
indicates that path yy to device xxxx(1) through
device xxxx(n) is logically available (online), and path
yy to device zzzz(1) through device
zzzz(n) is logically unavailable (offline).- yy
- is the logical channel path.
- xxxx
- zzzz
- are the real device numbers.
Response for No Devices on Path:
NO DEVICES ON PATH yy
indicates there are no
devices on the specified channel path.- yy
- is the logical channel path.
Response for Nonexistent CHPID:
INVALID CHPID yy
indicates that a nonexistent
channel path ID was specified.- yy
- is the nonexistent logical channel path.

Usage Notes
The following commands are used to find the virtual CHPID number for a virtual device. In this example, the device number is 191, the subchannel ID is 5, and the CHPID numbers are 60-67.
