Starting a Cartridge Tape Drive

You use the SCF START command to start a tape drive. The START command makes

a stopped tape process accessible to user processes.

When the START command finishes successfully, the tape drive is in the STARTED

state.

Examples

To start tape drive $TAPE0, enter the following command:

->START $TAPE0

To then check the status of $TAPE0, enter the following command:

->STATUS TAPE $TAPE0

Tape drive $TAPE0 is now in the STARTED state.

For more on the START command, see the SCF Reference Manual for the Storage

Subsystem.

Stopping a Cartridge Tape Drive

You use the SCF STOP command to stop access to a tape drive in an orderly manner

(which means that the tape is stopped after any current activity finishes). When the

STOP command finishes, the tape drive is left in a STOPPED state. The tape drive

remains configured in the system configuration database.

Example

To stop access to the tape drive $TAPE1, enter the following command:

->STOP $TAPE1

To then check the status of $TAPE1, enter the following command:

->STATUS TAPE $TAPE1

Tape drive $TAPE1 is now in the STOPPED state.

For more on the STOP command, see the SCF Reference Manual for the Storage

Subsystem.
