LD DISCONNECT [LDAn:]

 	This command will disconnect the Logical Disk device from the
 	Logical Disk file, or from the physical disk.

1    /ABORT

 	This qualifier can be used if the normal disconnect command does
 	not disconnect the file (for example, when the file has been
 	deleted). The ABORT qualifier disconnects the Logical Disk as it
 	is (No checks.)

 	When the physical disk is dismounted, and the logical disk
 	is still active,the physical disk will enter a marked for dismount
 	state until the logical disk is no longer connected.
 	The steps to follow if this happens are described below;

 		$ DISMOUNT LDA1:
 		$ LD DISCONNECT/ABORT LDA1:
 		$ DISMOUNT DDan:

 	Be careful using the ABORT qualifier because it disconnects the
 	Logical Disk independent of the state it is in.

2    /ALL

 	This qualifier disconnects all LDAn devices.
 	No devicename has to be given in this case.

3    /LOG

  /LOG
  /NOLOG (default)

 	Shows the status after the device has been disconnected.

4    /TRUNCATE

 	This qualifier will truncate the container file to the highest written
 	block. This can be used to trim excess blocks which may be left over
 	from an extend operation.
