Converting LVM to VxVM

Examples

Example: Invoking the vxvmconvert menu with vxinstall

The example below describes the conversion of a LVM volume group vg01 with disks c5t3d0 and c5t4d0 into

the VxVM rootdg disk group using vxinstall -C.

To invoke the vxvmconvert menu with vxinstall, invoke the following:

# vxinstall -C

vxinstall -C displays the Convert an LVM Volume Group to VxVM rootdg Menu and produces the following

example output:

Convert an LVM Volume Group to VxVM rootdg

Menu: LVM_Conversion/Convert_LVM_VGs

Use this operation to initialize your VxVM ’rootdg’ disk group by

converting an existing LVM Volume Group. This adds the disks

of the LVM Volume Group to the ’rootdg’ disk group in VxVM and

replaces existing LVM volumes in that group with VxVM volumes.

LVM-VxVM Volume Group conversion may require a reboot for the

changes to take effect. For this release, only Non-root LVM

Volume Groups can be converted.

At the prompt enter the name of the LVM Volume Group you wish to

convert. For a list of all available LVM Volume Groups, use

the ’listvg’ option. Some LVM Volume Group selection examples:

listvg: list all LVM Volume Groups

list: list all disk devices

vg_name: a single LVM Volume Group, named vg_name

Select Volume Group to convert : [<vg_name>,list,listvg,q,?] vg01

vg01

Convert this Volume Group? [y,n,q,?] (default: y)

The following disks have been found in the vg01 volume group and

will be configured for conversion to VxVM disk groups.

c5t3d0 c5t4d0

The disk device c5t3d0 will be converted and added to the disk

group rootdg with the disk name disk01.

The c5t3d0 disk has been analyzed and prepared for conversion.

The disk device c5t4d0 will be converted and added to the disk

group rootdg with the disk name disk02.

The c5t4d0 disk has been analyzed and prepared for conversion.

The first stage of the conversion operation has completed

successfully. If you commit to the changes hereafter, the

system will attempt to umount all of the associated file
