The former (rootvg-homelv) is indirectly available via hinv.map.dmname but
the latter (/home -> mount point) is not necessarily a one-to-one mapping
with device, so gets more complicated.

You might also find pmdamounts(1) of use for your situation, in recent PCP
versions it exports all of the same metrics as filesys.* for a specified
set of mount points.

cheers.
