Responses
2. You can use the QUERY VIRTUAL command to determine the subchannel
number associated with a virtual device.
3. The response to this command is a header line followed by a line of information
for each SCHIB that you specify. (The header line identifies, column by column,
the SCHIB information below it. See “Responses” below.)
4. For more information, see “Usage Notes” on page 282.
Response 1: When EXP is not specified
SCHIB DEV INT-PARM ISC FLG LP PNO (Con’t)
nnnn nnnn nnnnnnnn n nn nn nn
LPU PI MBI PO PA CHPID0-3 CHPID4-7
nn nn nnnn nn nn nnnnnnnn nnnnnnnn
If an interrupt is pending for the virtual subchannel, the following line describes the
pending interrupt:
KEY ECC FPI ZN SCTL CCW-ADDR DS SS CNT EXT-LOG
n n n n nnnn nnnnnnnn nn nn nnnn nnnnnnnn
Response 2: When EXP is specified
SCHIB DEV INT-PARM ISC FLG MBI FLG2 MBA
nnnn nnnn nnnnnnnn n nn nnnn nn nnnnnnnnnnnnnnnn
Response header lines contain headings from the list below, a brief description is
included.
