DescriptionSubfieldField
An 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 in data migrations that use 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 receive the lowest available ID that is equal to or greater than
the specified value.

ing field for de-
tails)

About clustered-host storage
Clustered-host storage is a storage configuration that is created when volumes are allocated to a new
host that is added to a host group (also known as a host cluster).
When creating clustered-host storage, you add the WWN of the newly added host to the host group
to which the WWN of an existing host belongs, and you set LUN paths from the newly added host
to the same volumes as those for an existing host.
For example, to better manage and distribute the load on your applications and resources, update
the existing host group by creating clustered-host storage using existing volumes by allocating them
to a new host in the host group.
Newly allocated volumes represent additional storage resources for a new host. Clustered-host storage
supports the reallocation of existing volumes within the host group to meet specific needs.
The following figure illustrates the process of adding a host to create clustered-host storage in a system.
