Overview of Changes by Command
vgcreate (1M)
• vgcreate is changed. It can be used as before to create 1.0 volume groups. To create 2.x volume groups, you
must use new options. For more information, see “Creation of a volume group” and “How to Provision a 2.x
Volume Group”.
vgextend (1M)
• The –f option is obsolete on a 2.x volume group. If used on a 2.x volume group, vgextend displays a
warning.
• The –z y option is invalid on a 2.x volume group. If used on a 2.x volume group, vgextend fails.
• The –z n option is obsolete on a 2.x volume group. If used on a 2.x volume group, vgextend displays a
warning.
• vgextend on a 2.x volume group fails if the volume group is already at the maximum size specified with
vgcreate.
• vgextend on a 2.x volume group displays a warning if only part of the physical volume can be added to the
volume group. If adding the whole physical volume results in exceeding the maximum size of the volume
group, only a part of the physical volume is added.
