Veritas Volume Manager 5.0 Migration Guide, HP-UX 11i v3, First Edition, May 2008

36 Converting LVM to VxVM
Examples
Use this operation to analyze one or more LVM volume groups for
possible conversion using the VxVM Volume Manager. This
operation checks for problems that would prevent the conversion
from completing successfully. It calculates the space required
to add the volume groups disks to a Volume Manager disk group,
and to replace any existing partitions and volumes with Volume
Manager volumes, plexes, and sub-disks.
More than one volume group or pattern may be entered at the
prompt.
Here are some LVM volume group selection examples:
all: analyze all LVM Volume Groups (all except Root VG)
listvg: list all LVM Volume Groups
list: list all disk devices
vg_name:a single LVM Volume Group, named vg_name
<pattern>:for example vg08 vg09 vg05
Select Volume Groups to analyze :
[<pattern-list>,all,list,listvg,q,?] vg08
Name a new disk group [<group>,list,q,?] (default: dg08)
The following disk has been found in the vg08 volume group and
will be analyzed for VxVM conversion.
disk12
To allow analysis, a new VxVM disk group, dg08, will be
fabricated and the disk device disk12 will be added to the disk
group with the disk name dg0801.
The disk12 disk has been configured for conversion.
The first stage of the Analysis process has completed
successfully.
Second Stage Conversion Analysis of vg08
Analysis of vg08 found insufficient Private Space for conversion
SMALLEST VGRA space= 176
RESERVED space sectors = 78
PRIVATE SPACE/FREE sectors = 98
AVAILABLE sector space = 49
AVAILABLE sector bytes = 50176
RECORDS neededs to convert = 399
MAXIMUM records allowable= 392
The smallest disk in the Volume Group (vg08) does not have
sufficient private space for the conversion to succeed. There is
only enough private space for 392 VM Database records and the
conversion of Volume Group (vg08) would require enough space to
allow 399 VxVM Database records. This would roughly translate to
needing an additional 896 bytes available in the private space.
This can be accomplished by reducing the number of volumes in
