Verified. From the 5.5 "Administrators Reference" page 420 under
DISCARDdata=Yes

If the volume being deleted is a primary storage pool volume, the server
checks whether any copy storage pool has copies of files that are being
deleted. When files stored in a primary storage pool volume are deleted,
any copies of these files in copy storage pools are also deleted.

Euh, wrong.  You delete all primary pointers to the file and this deletes
also
all copy storage pool pointers.  It _will_ also delete the copy storage
data.

So a =del vol <....> discarddate=yes" WILL also delete the copy storage
pool
data !!
