Unhappy Change Password on Encrypted Disk: Invalid Request?

Hi all.

I have an internal hard disk, auxiliary to my startup disk, which is CoreStorage encrypted, originally via diskutil cs. I am trying to change the password to one that is more secure—I dutifully read the manpage and came up with the following command:

cat passwordChg.txt | diskutil cs passwd 52DC2A4E-A74A-409A-B8B4-B440AC4F8686 -stdinpassphrase
where passwordChg.txt contains the old and new passwords separated by newline. Instead of doing anything, diskutil replies:

Started CoreStorage operation
Error: -69886: Invalid request
Huh? I tried several variations (sudo, synonyms for keywords, specifying the passwords on the command line, etc.) which all give precisely the same error. Disk offers to change the password, and makes no complaint, but in fact changes nothing.

I have also tried the command with each one of the UUIDs in the coreStorage listing—each of which I'm told "is not a CoreStorage Logical Volume UUID." They are:

+-- Logical Volume Group 059FCC6B-DA8D-4590-9D67-4C4CE28FCF02

Any ideas or suggestions are greatly appreciated.
Is that a crosswalk in my Dock?
