Example: listing disk information
The list option of vxvmconvert displays information about the disks on a system. Select the list option from the vxvmconvert Main Menu:
Menu: Volume Manager/LVM_Conversion/list
# list
Use this menu option to display a list of disks. You can also choose to list detailed information about a disk by entering a specific disk device address.
Enter disk device or "all" [<address>,all,q,?](default: all) x

Example: listing LVM volume group information
To list LVM volume group information, use the listvg option of vxvmconvert.
Select the listvg option from the vxvmconvert Main Menu:
Menu: Volume Manager/LVM_Conversion/ListLVMVolumeGroups
# listvg
Use this menu option to display a list of LVM volume groups. You
can also choose to list detailed information about the LVM
volume groups at a specific disk device address.
Select the Volume Group as follows:
Enter Volume Group (i.e.- vg08) or "all" [<address>,all,q,?]
(default: all)

[<address>,none,q,?] (default: none) none
To display detailed information about a volume group, select any of
the volume groups from the above list.

Note
The volume groups you want to convert must not be a root volume group or have bootable volumes in the group.
Example: analyzing LVM volume groups
To analyze one or more LVM volume groups:
# vxvmconvert
Volume Manager Support Operations
Menu: VolumeManager/LVM_Conversion
1 Analyze LVM Volume Groups for Conversion
2 Convert LVM Volume Groups to VxVM
3 Roll back from VxVM to LVM

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.

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.
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
the (vg08) Volume Group, and allowing that for every volume
removed, the number of Database records required would be
reduced by three. This is only a rough approximation, however.
