VERITAS Volume Manager 4.1 Migration Guide

Converting LVM to VxVM
Examples
Chapter 2 23
Menu: Volume Manager/LVM_Conversion/Analyze_LVM_VGs
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.
c4t8d0
To allow analysis, a new VxVM disk group, dg08, will be fabricated
and the disk device c4t8d0 will be added to the disk group with
the disk name dg0801.
The c4t8d0 disk has been configured for conversion.
The first stage of the Analysis process has completed successfully.
