DISPLAY SCHIB
Authorization
Privilege Class: G
Purpose
Use DISPLAY SCHib to see your subchannel information blocks (SCHIB).
Operands
- EXP
- specifies that extended channel measurement information is to be displayed.
- ALL
- specifies that SCHIBs for all virtual devices are to be displayed.
- vsch1
- identifies the starting (or only) virtual subchannel whose SCHIB is to be displayed.
- : END
- - vsch2
- vsch2 specifies that all SCHIBs in the range
vsch1 to vsch2 are to be displayed, or that all
SCHIBs from vsch1 to the highest number subchannel are to be displayed.
END is the default if you specify a hyphen (-), or a colon (
:
). A colon (:
) means the same as a hyphen (-) when specifying a range. - END
- . count
- count identifies the number of consecutive SCHIBs starting at
vsch1 that are to be displayed. Specify END to display all SCHIBs from
vsch1 to the highest number subchannel. END is the default if you specify
a period (
.
).
Usage Notes
- If you specify a list of SCHIBS, and one is not found, the DISPLAY command terminates at the
first SCHIB not found. For example, if you enter display SCHIB 0022 0033 0055
0011, and subchannel 0055 is not found, only SCHIB 0022 and 0033 will be displayed.
If you specify a range of SCHIBs, the DISPLAY command terminates if the first SCHIB in the range is not found. Otherwise, all those SCHIBs that were found are displayed.
- You can use the QUERY VIRTUAL command to determine the subchannel number associated with a virtual device.
- 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.)

Responses
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
