# vgs --foreign
# all cases show all local and foreign
#
# vgs foo
# a. not found
# b. not found
# c. show 1 local
# d. show 1 local
# e-g. dup error
#
# vgs --foreign foo
# a. show 1 foreign
# b. dup error
# c. show 1 local
# d. show 1 local
# e-g. dup error
#
# vgchange -ay
# a. none
# b. none
# c. activate 1 local
# d. activate 1 local
# e-g. activate 2 local
# (if both local vgs have lvs with same name the second will fail to activate)
#
# vgchange -ay foo
# a. none
# b. none
# c. activate 1 local
# d. activate 1 local
# e-g. dup error
#
# lvcreate foo
# a. none
# b. none
# c. create 1 local
# d. create 1 local
# e-g. dup error
#
# vgremove foo
# a. none
# b. none
# c. remove 1 local
# d. remove 1 local
# e-g. dup error
# (in a couple cases test that vgremove -S vg_uuid=N works for local vg when local dups exist)
