uname phy

appeared in in step 1, continue to step 3. (Only a SCSI device that appears in step
1 can be migrated to an HDLM device.)
3. If domainU is running, stop it.
If domainU has been set to automatically start when domain0 starts, temporarily
change the setting so that domainU will not start automatically.
4. Specify the settings so that SCSI devices are not used in domainU.
Disable the block device settings from domainU. For details, see the Linux
documentation.
5. Specify the settings so that HDLM devices are used in domainU.
Set (export) the block devices to domainU. For details, see the Linux
documentation.
Make sure that you specify the settings based on the correspondence between the
HDLM and SCSI devices displayed in step 1.
6. Change the single-path configuration to a multi-path configuration.
7. Start domainU.
If you temporarily changed the settings in step 3 so that domainU would not
automatically start, restore the previous settings.
