Yes, you're right. I wasn't thinking of just having the space available
in the next slice, I was thinking I'd be going through the hardware raid
controller to enlarge a logical drive or something. Thanks.

I haven't tried it, but it's documented:
http://seer.support.veritas.com/docs/264220.htm, page 100, under
FlashBackup supports the following I/O system components: ufs,
VxFS, and Windows NTFS file systems, VxVM volumes and LVM volumes, and
disks. Other components (such as non-VERITAS volume managers or storage
replicators) are not supported.
plus, a pre-sales engineer confirmed that shortcoming for me.
