AIX lsdevinfo

The lsdevinfo utility appears to an undocumented command. However it looks like it could come in handy occasionally. Here are some examples of using it on AIX 7.1:

# oslevel -s

7100-00-01-1037

# lslpp -w /usr/sbin/lsdevinfo

  File                                        Fileset               Type

# lsdevinfo -h

Usage:

lsdevinfo [-q Criteria] [-F Format] [-R] [-c] [-h]
