Man documentation for diskutil...

 

http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/ man8/diskutil.8

 

... states that the diskutil eject command can be used to "re-lock" a corestorage volume that has been previously unlocked:

 

"To 're-lock' the volume, make it offline again by ejecting it, e.g. with diskutil eject."

 

I have an external hard drive with several Filevault 2 encrypted partitions (OSX 10.8.3) .  Once a volume is unlocked using diskutil corestorage unlockVolume, when the volume is subsequently ejected using diskutil eject, it  shows the disk as unlocked after ejecting.  After ejecting, I can look with diskutil corestorage list and find:

 

|               Encryption status:      Unlocked

 

Indeed, after ejecting, the disk can be re-mounted and the files accessed without re-entering the Filevault password for the volume.

 

The only means I have for restoring the disk to the locked status is to restart the machine.

 

What is the correct way to "re-lock" a corestorage volume?

 

Below is the output for the drive using diskutil corestorage list after unlocking with diskutil corestorage unlockVolume and then ejecting with diskutil eject.
