2. Use the VSCLOSE command to place the volume set in the LONER
state. The VSCLOSE command is described in this chapter. Then
use the DSTAT command to display the states of all the volumes.

| volutil: :VSCLOSE BSET |
| volutil: :DSTAT |
| |
| LDEV-TYPE STATUS VOLUME (VOLUME SET - GEN) |
| --------- ------- --------------------------- |
| 21-079330 LONER BVOL1 (BSET-0) |
| 22-079350 LONER BVOL2 (BSET-0) |
| 23-079350 LONER BVOL5 (BSET-0) |

3. Now that you have verified that the volume set is in the LONER
state, you can use the SCRATCHVOL command to place the volume in
the SCRATCH state. Refer to the SCRATCHVOL command for more
information.
4. Use the FORMATVOL command to format the volume on LDEV 23. After
you format the volume, the volume will be in the UNKNOWN state.
Again use the DSTAT command to verify the state of the volume.
