The shaded portion shows the SCSI device to be managed by HDLM.
Execute the following command on this SCSI device to unmount it:

.
If the disks are set to be mounted automatically when the host starts,
delete this setting from the /etc/fstab file.

Comment out the shaded portions by placing a hash mark (#) at the
beginning of each line. The Linux functionality that adds LABEL= to a SCSI
device is not supported in HDLM. Do not use this functionality.
Checking the Volume Group
If you have already created a physical volume, volume group, or logical
volume by using LVM, you can use the procedure described in Settings for
LVM2 on page 3-196 only when all of the conditions below are satisfied.
Migration is not affected even when a logical volume or file system has been
created.
