RSRCNAME

Specifies the resource name that describes the automatic call unit port.

Note:

Use the Work with Hardware Resources (WRKHDWRSC) command with *STG specified on the TYPE parameter to determine the resource name.

SWTSET

Specifies a 1-character switch setting field with a value ranging from 0 through F.

Note:

This parameter is required for a device type of 3422, 3430, 3480, or 3490, but is not allowed for other device types. Valid values for a 3422, 3480 or 3490 device type ranges from 0 through F. Valid values for a 3430 device type range from 0 through 3.

 

Optional Parameters

ONLINE

Specifies whether this object is automatically varied on at initial program load (IPL).

*YES: The object is automatically varied on at IPL.

*NO: This object is not automatically varied on at IPL.

CTL

Specifies the name of the controller description to which this object is attached.

Note:

This parameter is valid only for 3422, 3430, 3480 and 3490 device types.

ASSIGN

Specifies whether the tape drive is assigned to the system when it is varied on.

*YES: The tape drive is assigned when the device is varied on.

*NO: The tape drive is not assigned when the device is varied on.

UNLOAD

Specifies whether the tape drive is unloaded when the device is varied off.

*YES: The tape drive is unloaded when the device is varied off.

*NO: The tape drive is not unloaded when the device is varied off. The tape is rewound, but not past the beginning-of-tape marker.

MSGQ

Specifies the name of the message queue to which messages are sent.

*SYSOPR: Messages are sent to the system operator message queue (QSYS/QSYSOPR).

message-queue-name: Specify the name of the message queue to which operational messages are sent.

The name of the message queue can be qualified by one of the following library values:

*LIBL: All libraries in the job's library list are searched until the first match is found.

*CURLIB: The current library for the job is searched. If no library is specified as the current library for the job, the QGPL library is used.

library-name: Specify the name of the library to be searched.

AUT

Specifies the authority given to users who do not have specific authority to the device description, who are not on an authorization list, and whose user group has no specific authority to the device description.

*LIBCRTAUT: The authority for the object is the same as the create authority for QSYS. The create authority for QSYS can be displayed by using the Display Library Description (DSPLIBD) command. If the create authority is changed with the Change Library (CHGLIB) command, the new authority does not affect existing objects.

*CHANGE: The user can perform all operations on the object except those limited to the owner or controlled by object existence authority and object management authority. The user can change and perform basic functions on the object. Change authority provides object operational authority and all data authority.

*ALL: The user can perform all operations except those limited to the owner or controlled by authorization list management authority. The user can control the object's existence, specify the security for the object, change the object, and perform basic functions on the object. The user also can change ownership of the device description.

*USE: The user can perform basic operations on the device description, such as running a program or reading a file. The user cannot change the device description. *USE authority provides object operational authority, read authority, and execute authority.

*EXCLUDE: The user cannot access the device description.

authorization-list-name: Specify the name of the authorization list used.

TEXT

Specifies the text that briefly describes the device file. More information on this parameter is in Commonly used parameters.

*BLANK: Text is not specified.

'description': Specify no more than 50 characters of text, enclosed in apostrophes.
