the specific device. The information presented in the subchannel details is taken from the Subchannel-
Information Block (SCHIB). The Subchannel-Information Block contains - beneath other areas - the Path-
Management-Control Word (PMCW) and the Subchannel-Status Word (SCSW). The subchannel infor-
mation shown here displays words 0-6 of the SCHIB (the Path-Management-Control Word). More details
can be found in the “DS” console command description in the “User Reference” manual.

Clicking on the “Select / Refresh” button updates the information shown. Selecting another device from
the drop-down box and clicking on the “Select / Refresh” button displays the subchannel details for the
newly selected device without the necessity to go back to the device list first.
