DEVSERV PATHS

You can use the DEVSERV PATHS command to display the number of configured cylinders for a device or range of devices under CYL header. If a device is part of a DUAL COPY pair (devices behind a 3990-3 or older), then the ALT dddd is displayed under the CYL header. The first character of the UNIT number represents the subchannel set number.

Figure 1 shows the output of the DEVSERV P,F4A command.
