Last I checked it wasn't supported so I have to use zfsadm to do it prior to copy (in particular my cloning process of my "sysres" maintenance zFS files). As far as I know, that quiesce call / API is the exact same for HFS and zFS so it would be a trivial change for the software to just check for zFS and do the quiesce if HFS=QUIESCE was specified instead of ignoring it as it does today. Innovation's support has always been top notch but this particular item really irks me considering I've had zFS set up since z/OS 1.4. have been using zFS regularly since z/OS 1.6 and all but eliminated HFS usage since z/OS 1.8.
