1 The old form of this oper<strong>and</strong>, CFS, is still supported for compatibility.<br />

2 For coupling channels, the UNIT_ADDRESS <strong>and</strong> UNITADD oper<strong>and</strong>s are ignored.<br />

3 You can specify a maximum of 8 control unit numbers.<br />

4 You can specify these oper<strong>and</strong>s in any order.<br />

DEFINE DEVICE / IODEVICE<br />

5 A preferred path must not be specified for a device connected to a control unit for which<br />

z/OS ® –managed paths are being used. Although the comm<strong>and</strong> will not prevent you from doing so,<br />

the use of preferred paths in a managed-path environment will adversely affect z/OS’s ability to<br />

manage channel-path workloads.<br />

6 For processors in LPAR mode this oper<strong>and</strong> is required. Otherwise, it is not applicable <strong>and</strong> should<br />

not be specified.<br />

7 The maximum number of logical partition names you can specify depends on the capabilities of<br />

your processor.<br />
