Notes:
  • 1 This operand is required for privilege class G users who also have privilege class B.

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.

QUERY VIRTUAL 191
