Volume migration requirements
All volumes for which data migration is to be performed must meet the following conditions:
• Migration-source and migration-target volumes exist within one of the following storage systems
(chassis):
• P9500 Disk Array
• XP24000/XP20000
• XP12000/XP10000/SVS200
• The emulation type, number of blocks, and size are the same for the source and target migration
volumes. However, note the following exceptions:
• If the micro version of XP24000/XP20000 is 60-03-20-00/00-xx or later and if both the mi-
gration source and the migration target volumes are THP/Smart volumes, the emulation type
can be between OPEN-V and OPEN-0V.
• If a volume whose emulation type is OPEN-V is a normal volume, and if the size of a migration
target volume is larger than a migration source volume, a volume that has the same size of the
migration source volume is re-created. The remaining capacity can be reused. If you set a
value for the property migration.plan.candidateCapacityGroupDisplayMaxCount
in the migration.properties file, you can specify how many volumes with a larger capacity
than the migration source volume to display, in addition to the volumes with the same capacity
as the migration source volume.
• The LDKC:CU:LDEV number for the volume is in the range from 00:00:00 to 00:FF:FF
• Volumes can be accessed, and are not reserved by other programs, Device Manager, or tasks.
• If the emulation type is not OPEN-V, and both the migration source and the migration target
volumes are normal, or both are CVS volumes.
Volume migration requirements related to volume type
Whether you can select a volume as a migration source or migration target depends on the volume
type. The following table shows which volume types can and cannot be selected as migration sources
and targets.
