Settings for Using a Logical Volume (LVM2) on an HDLM Device as a Boot Disk
To migrate a single-path boot disk environment that uses a logical volume
(LVM2) on a SCSI device to a multi-path boot disk environment that uses a

See steps 1 to 9 in Settings for Using a Logical Volume (LVM2) on an
HDLM Device as a Boot Disk on page 3-155 .
