Required keywords

DEVTYPE

Specifies the tape device type that the TAPECNTL operation is to be performed against. Eligible device names are 3400 and TAPE. When either 3400 or TAPE is specified, Stand-Alone Services attempts to determine the device type from the self-description information. If the device self-description information indicates a supported device type, Stand-Alone Services uses the returned device type for processing. When a device does not support self-description, Stand-Alone Services processes the device differently depending on whether 3400 or TAPE is specified. Abbreviation: DEV.

3400: specifies device types 3420, 3422, and 3430. If the device does not support self-description, Stand-Alone Services may not be able to determine if the device is a tape drive. Stand-Alone Services issues the rewind or unload instruction to the device anyway. When the device is not a tape drive, unpredictable results may occur.
TAPE: specifies all other supported tape devices. Stand-Alone Services does not issue rewind or unload instructions to the device when Stand-Alone Services cannot determine the device type from the self-description.

UNITADDR (ccuu)

Specifies the unit address of the device against which the TAPECNTL operation is performed. You can specify a 3-digit or 4-digit address. Abbreviations: UNIT and ADDR.

REWIND

Specifies a rewind operation. Specify either the REWIND keyword or the UNLOAD keyword, not both. Abbreviation: REW.

UNLOAD

Specifies that a rewind and unload operation be performed. If the tape drive is in an IBM® tape library, the tape is demounted if necessary. Abbreviation: UNL.
