Examples<br />

rdev<br />

rdev1-rdev2<br />

Privilege Class: B<br />

Use this SET RDEVICE comm<strong>and</strong> to tell <strong>CP</strong> that tape units are at certain device<br />

addresses.<br />

rdev<br />

rdev1-rdev2<br />

specifies one or more real device numbers to be defined or changed. Each rdev<br />

specified must be a hexadecimal number between X'0000' <strong>and</strong> X'FFFF'. The<br />

maximum number of devices allowed within a range is 256.<br />

TYpe 3422<br />

specifies an <strong>IBM</strong> 3422 tape unit.<br />

TYpe TAPE<br />

specifies an <strong>IBM</strong> tape unit that can be dynamically sensed by <strong>CP</strong> (such as an<br />

<strong>IBM</strong> 3480 or 3490 tape unit).<br />

SENSed<br />

tells <strong>CP</strong> to use the information returned from a sense ID request to determine<br />

the characteristics of this tape unit. If omitted, the default is SENSED.<br />

NOTSENSed<br />

tells <strong>CP</strong> not to use the information returned from a sense ID request to<br />

determine the characteristics of this tape unit.<br />

Example 1:<br />

To specify a 3422 tape unit at device number 0310, enter the following SET<br />

RDEVICE comm<strong>and</strong>:<br />

set rdevice 0310 type 3422<br />

Example 3:<br />

TYpe<br />
