LU Number

Option for manually specifying the starting virtual LDEV ID to use for
allocated volumes. Volumes for which virtual IDs have not been specified
are assigned a new virtual LDEV ID when they are allocated to a host that
belongs to resource groups used for a data migration that uses virtual IDs.
Virtual LDEV IDs are assigned automatically by default, with unused IDs
assigned to volumes in ascending order. If a user manually specifies an
ID, volumes will receive the lowest available ID that is equal to or greater
than the specified value.
