LVM Volume Group Dynamic LUN Expansion (DLE) and Contraction (DLC) (September 2009)

77
• Physical volume "/dev/disk/disk46" requires reconfiguration for expansion.
In review mode, for a DLE operation, vgmodify reports that the physical volume was
expanded by at least one extent, and that reconfiguration of the physical volume is required
to make use of the extra space
• The physical volume "/dev/disk/disk48" does not need to be reconfigured for expansion
since the available disk space is less than the size of one extent.
In review mode, or for a failed change mode, for a DLE operation, vgmodify reports that
the physical volume size either has not changed, or has been expanded less than the size of
one extent. Therefore, no reconfiguration is performed.
• Current number of extents: 12790
Number of extents after reconfiguration: 25590
In review mode, vgmodify reports that the reconfiguration will result in the number of extents
for the physical volume being increased. The output might also report that the number of
extents is staying the same, or being reduced.
• Previous number of extents: 12790
Number of extents after reconfiguration: 25590
In change mode, after successful reconfiguration of the physical volume, vgmodify reports
that the number of extents for the physical volume was increased. It might also report that the
number of extents stayed the same, or was reduced.
• Physical volume "/dev/disk/disk46" was not changed.
Either review mode, or change mode in which vgmodify did not detect that a
reconfiguration was required.
• Physical volume "/dev/disk/disk46" was changed.
During a change mode operation, a physical volume was reconfigured.
• Reconfiguration to expand physical volume "/dev/disk/disk46" succeeded.
A DLE operation succeeded in reconfiguring a physical volume.
• Physical volume "/dev/disk/disk46" requires reconfiguration to be provisioned to the
requested maximum volume group size 8388608 MB.
In review mode for either maximum VG size increase or decrease, vgmodify determined
that the physical volume can be reconfigured to the requested size.
