Specify Device Numbers

Specify a hardware device on an SOF command as one of the following:

• A hexadecimal local z/OS device number, optionally suffixed with a period followed by the CCI system name, SMFID, or LPAR name of the owning system.

  Examples: 1A, 2B.SYSA

• The hexadecimal SOF relative global device number, optionally suffixed with a period followed by an asterisk.

  Examples: 1A, 2B.*

If not suffixed, the common SOF command parameters LOCAL, GLOBAL, and SYSTEM control how a device number is interpreted.

In all cases, a device number is automatically padded on the left with zeros if less than the expected number of digits is specified. The expected number of digits for a local z/OS device number is listed for each SOF command parameter.
