# set-sct command

The set-sct command attaches the SCT
drive to the current process. This must be executed before any other
tape handling commands. This command is provided for compatibility.

## Syntax

```
 set-sct {(options}
```

## Parameter(s)

| options | blocksize | Can be any value between 512 and 16384, but must be a multiple of 512. The default is 16384. |
| --- | --- | --- |
| h | High density, if available. | |
| l | Low density, if available. | |
| s | Standard density, if available. | |

## Description

The set-sct command specifies a 1/4-inch streaming tape unit as the
 peripheral storage device. The set-sct command automatically specifies a
 t-att (tape-attach) command and a t-rew (rewind)
 command.

 Make sure the hardware is present for a 1/4-inch drive. Otherwise, the port might wait
 indefinitely. If only one density is available, then it is used. The
 default is high density.

 Note: If there are more than one SCT devices, or one SCT device with multiple densities, the
 set-sct command selects the first device shown in the list produced by the
 list-device command. To select another SCT or another density, the
 set-device command must be used.
