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

/dev/rdsk/c2t3d0
/dev/rdsk/c3t4d0
Bootable disks (disks created using pvcreate –B or changed type using vgmodify –B y)
limit the space available for the VGRA. If this is not a boot volume group, use –B n to
change all the disks in the list to non-boot.
• Physical Extent zero is not free on all PVs. You will not achieve these values until the first
extent is made free (see pvmove(1M)) on all the following disks:
/dev/rdsk/c2t4d0
vgmodify was run with –n and it wants to lower the physical extent numbers on c2t4d0, but
to do this the first extent must be free so that its space can be given over to metadata.
• VGRA for the disk is too big for the specified parameters. Decrease max_PVs and/or
max_PEs.
The selected max_pv and max_pe values create a VGRA that is too large for the space
available on all physical volumes. The VGRA cannot be greater than the physical extent size.
• "/dev/rdsk/c2t4d0" size is limited by the maximum extents per PV to 56934400.
The disk /dev/rdsk/c2t4d0 was resized to a size greater than 56934400, but because of
the limitation of the current value of max_PE, LVM can only use 56934400 of the disk space.
• Error: The physical volume “/dev/rdsk/c2t4d0" does not need to be
reconfigured since the newly added space is less than the size of one
extent.
The disk /dev/rdsk/c2t4d0 was increased by a size less than the size of one physical extent.
• The physical volume "/dev/rdsk/c4t2d0" can be prepared for contraction to 40003 MB
without having to move any physical extents on it.
The minimum size to which the disk /dev/rdsk/c4t2d0 can be reduced without having to
move any of the physical extents.
• The physical volume "/dev/rdsk/c4t2d0" can be prepared for contraction to a minimum size
of 40003 MB after freeing up the last 7501 physical extents.
The minimum size to which the disk /dev/rdsk/c4t2d0 can be reduced after freeing up the
last extents 7501 extents using pvmove(1M) command.
• Error: The specified size for physical volume "/dev/rdsk/c4t2d0" is too small. The minimum
size to which the physical volume can be contracted to is 200 MB.
The specified size for the physical volume /dev/rdsk/c4t2d0 in the command line for DLC is
less than the metadata size.
