Select an operation to perform: 1

Analyze one or more LVM Volume Groups

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)

Each volume group will be analyzed one at a time. If there are any

in this list that you do not want to analyze, you can either

abort now or wait until a later time when you will be given an

opportunity to skip the analysis of any group(s) in this list.

The following disk has been found in the vg08 volume group and will

be analyzed for VxVM conversion.

c8t8d0

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.

Second Stage Conversion Analysis of vg08

Analysis of vg08 found sufficient Private Space for conversion

Conversion Analysis of c4t8d0 indicates that the Volume Group is

still in use, which may prevent the completion of the conversion

without having to reboot the system. You may want to double

check that none of the volumes in the volume group are in use

before continuing with the conversion.
