HP StorageWorks P9000 Tiered Storage Manager Software 7.1.1 CLI Reference Guide (TB585-96014, September 2011)

DescriptionItem
The controller logical device number of the migration target volume
Multiple lines are displayed for a volume when multiple volumes are available as
the migration target volume candidate. Volumes that are available as the migration
target volume include volumes that have larger capacities than the migration source
volume (and need to be re-created).
#2
The first candidate volume displays the controller logical device number followed
by an asterisk (*) and the controller logical device number of the migration source
volume in parentheses.

#1
There are two types of information for the #Target candidates for source LDEV line,
depending on the Tiered Storage Manager server settings. One type is migration target volumes
that have the same capacity as the migration source volume, and the other is migration target
volumes that have larger capacities than the migration source volume. One or both of these types
are displayed. If both types are displayed, they are output in the following order:
1. Migration target volumes that have the same capacity as the migration source volume
2. Migration target volumes that have larger capacities than the migration source volume
For a mixed display example, see Command execution example (1).
#2
If you do not want to display the volumes that have larger capacities than the migration source
volume as candidate volumes, specify 0 for the server.migrationPlan.candidateCapa-
cityGroupDisplayMaxCount key in the server.properties file.
Example and execution results
• Command execution example (1):
In this example, a candidate migration plan is created for when each volume in the MG011 migra-
tion group is migrated to the MegaTech-HighCost storage tier, in the
TSM_P9500@10.208.115.233 storage domain. In this example, the migration-target volumes
(the candidate volumes) contain the following two types of volumes: candidate volumes that have
the same capacity as the corresponding migration-source volumes and candidate volumes that
have a larger capacity than the corresponding migration-source volume.
