Conditions for data migration (Legacy mode)
The conditions for data migration in Legacy mode include conditions that apply to all volumes (volume
migration requirements), and conditions that depend on the type of volume (volume migration
requirements related to volume type).
For some volumes, the reasons why they cannot be selected as migration-source volumes or
migration-target volumes are displayed on-screen.
Volume migration requirements
All volumes for which data migration is to be performed in Legacy mode must meet the conditions
below:
• 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 use the
server properties, 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, 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.
