 lvmmigrate(1M)                                               lvmmigrate(1M)

 NAME    [Toc]    [Back]
      lvmmigrate - prepare root file system for migration from partitions to
      LVM logical volumes

 SYNOPSIS    [Toc]    [Back]
      /usr/sbin/lvmmigrate [-d disk_special_file] [-e file_system ...] [-f]
           [-i file_system ...] [-n] [-v]

 DESCRIPTION    [Toc]    [Back]
      The lvmmigrate command records the configuration information of the
      current system in the LIF volume of the boot section for use with a
      subsequent cold-install process.  If there is no LIF volume on the
      disk, lvmmigrate creates it using lifinit(1), then records the
      information in a LIF file named CUSTOM.  A copy of the LIF file is
      saved as /tmp/LVMMIGRATE.CFG.  The information is also written to file
      /tmp/LVMMIGRATE for reviewing.  The install process looks for the LIF
      file CUSTOM, and if it exists, uses the information found as the
      configuration defaults for the root volume group and the root file
      systems.  After the install process has completed, a copy of the
      CUSTOM final configuration can be found on the newly created system in
      the file /usr/lib/sw/hpux.install/config.local.

      All file system entries in the /etc/mnttab and /etc/fstab files are
      read.  lvmmigrate also searches for unmounted file systems and
      possible character data sections in unused disk areas.  The file
      systems appropriate for the root volume group are marked for
      migration.  The default file systems are: /, /home, /opt, /tmp, /usr,
      /var, and any file system with a mount path beginning with: /home/,
      /opt/, /tmp/, /usr/, /var/.

      lvmmigrate displays the following information on the standard output:
      disks and file system names that are marked for migration, disk areas
      and file systems to be backed up by the user, and instructions for

      After executing lvmmigrate, the user must back up the file systems and
      any raw device section having useful data to tape.  The system is then
      reinstalled on logical volumes using the configuration information
      recorded by lvmmigrate.

    Options    [Toc]    [Back]
      lvmmigrate recognizes the following options:

           -d disk_special_file     Use the specified root disk for
                                    reinstallation.  Without this option,
                                    the current root disk (where root file
                                    system / is currently located) is
                                    assumed and the configuration is
                                    recorded in the boot section.

                                    system from the root volume group.  Note

           -f                       Force the recording of configuration
                                    information.  Information is recorded in
                                    a LIF file named CUSTOM in the boot
                                    section.  Without this option, if there
                                    is a file system or LVM record in the
                                    boot section, no write is done and a
                                    warning message is displayed.

           -i file_system ...       Include each specified file system in
                                    the root volume group, along with the
                                    default file systems.

           -n                       Perform a "no write" operation for
                                    preview purposes.  Migration information
                                    is displayed on the terminal screen, but
                                    is not recorded in the boot section of
                                    the disk.  The CUSTOM LIF file is not
                                    written, but the files /tmp/LVMMIGRATE
                                    and /tmp/LVMMIGRATE.CFG are still

 EXAMPLES    [Toc]    [Back]
      Prepare a system for migration to root logical volumes.  Create a file
      in the LIF area that the cold-install can use to read default
      configuration information.  Specify verbose mode.  Create files
      /tmp/LVMMIGRATE and /tmp/LVMMIGRATE.CFG:

           lvmmigrate -v

      Display a detailed list of the disks, file systems, and possible raw
      data sections present in the current system.

           lvmmigrate -v -n

      Include file system /mnt in the root volume group for migration and
      exclude file system /usr/source.  Write configuration information in
      the boot section of disk /dev/dsk/c1t0d0:

           lvmmigrate -d /dev/dsk/c1t0d0 -i /mnt -e /usr/source

 WARNINGS    [Toc]    [Back]
      Use of the -f option results in overwriting the contents of the boot

      section.  Before using the -f option be sure to back up all data on
      the boot section of the disk specified with the -d option.

      If there is no LIF volume, lvmmigrate uses lifinit to create it (see
      lifinit(1)).  If file CUSTOM already exists in the LIF volume,
      lvmmigrate rewrites it.

      Caution: All data on disks being used for reinstallation must be
      backed up to a separate device because the install process overwrites
      data on all disks used in the new root volume group.
