NAME

       vxvmconvert - convert LVM volume groups to VxVM disk groups

SYNOPSIS

       vxvmconvert

DESCRIPTION

       vxvmconvert  is a menu-driven program to convert an HP Logical Volume Manger (LVM) configuration to a Veritas Volume Manager configuration.
       This man page is a brief overview of vxvmconvert.  Refer to the Veritas Volume Manager Migration Guide for a  detailed  description  before
       using the conversion procedure.

       The  vxvmconvert  script  is  interactive and prompts you for responses, supplying defaults where appropriate.  There is a Help facility at
       every prompt.  Enter a question mark (?) at a prompt to display a context-sensitive help message.

       With vxvmconvert you can identify LVM volume groups, list disks, analyze volume groups for conversion and complete the  conversion  of  LVM
       volume groups to VxVM disk groups.

       LVM configurations are converted at the volume group level.  All disks used in a volume group are converted together.  You cannot use vxvm-
       convert to convert unused LVM disks (those not part of an LVM volume group) to VxVM disks. To convert unused LVM  disks,  use  pvremove	to
       take  the  disk	out  of LVM control, then initialize the disk for VxVM use by using vxdiskadm (see pvremove(1M) and vxdiskadm(1M) for more
       information).

       vxvmconvert changes disks within LVM volume groups to VxVM disks by replacing the areas of the disks used for LVM configuration information
       and  with  the  equivalent VxVM volume configuration information.  Portions of the disks used for user data, such as file systems and data-
       bases, are not affected by the conversion.

       The conversion process changes the names by which your system refers to the logical storage, so must be done offline.  No applications  can
       access  data in the volume groups undergoing conversion.  You must unmount file systems using those volumes and shut down any applications,
       such as databases, that might use the volumes directly.

OPERATIONS

       Analyze LVM Volume Groups for Conversion
		 Use this operation to analyze one or more LVM volume groups for conversion to use by VxVM.  The analysis checks for problems that
		 can  prevent the conversion from completing successfully.  It calculates the space required to add volume group disks to a Volume
		 Manager disk group.  More than one volume group may be entered at the prompt.	A grep-like pattern may be used to select multiple
		 volume groups.

		 See the ``Limitations in Conversion'' section in the Volume Manager Migration Guide for more information.

       Convert LVM Volume Groups to VxVM
		 Converts  one	or  more LVM volume groups to one or more VxVM disk groups.  This adds the disks to a VxVM disk group and replaces
		 existing LVM volumes with VxVM volumes.

		 vxvmconvert prompts you to name the VxVM disk group that replaces the LVM volume group being converted.  A default  is  suggested
		 at the prompt.  For example, if you are converting a volume group vg08, vxvmconvert renames it as dg08.

		 See  to  the  sections  ``Dealing with New Logical Volume Names'' and ``Tailoring your VxVM Configuration'' in the Volume Manager
		 Migration Guide for more information.

       Rollback from VxVM to LVM
		 Rollback reverts VxVM disk groups to LVM volume groups.  vxvmconvert provides a limited snapshot capability for the LVM  metadata
		 in a converted volume group.  A snapshot is a simple protection method to use during conversion.

		 Caution! Do not use this operation if the VxVM disk group was modified since the conversion.

		 See  to the section ``Restoring LVM Volume Groups and Disaster Recovery'' in the Volume Manager Migration Guide for more informa-
		 tion.

       List Disk Information
		 Displays information about the disks on a system.  You can obtain detailed information about a disk by entering a  specific  disk
		 device address.

       List LVM Volume Group Information
		 Listvg  displays  a  list of LVM volume groups.  You can obtain detailed information about an LVM volume group at a specific disk
		 device address.
