Notes:
1. When the migration source volume is a LUSE, a migration target must be selected for each volume that
constitutes the LUSE. Migration target volumes must also satisfy the following conditions:
• All of the migration target volumes are internal volumes, or all are external volumes.
• The I/O suppression mode, cache mode, and CLPR of all migration target volumes are the same.
• Migration target volumes are not THP/Smart volumes.
Also, for Tiered Storage Manager to automatically create pairs for migration sources and migration targets,
we recommend that the following conditions also be met:
• If the migration target volumes are external volumes, all of the volumes are in the same external storage
system.
• The RAID level, drive type, and SLPR (storage management logical partition) of all migration target
volumes are the same.
Note that if you are migrating a LUSE volume of an XP24000/XP20000 storage system for which the
micro version is earlier than 60-05-12-00/00, you must not perform I/O operations on the volumes while
migration is being executed.
2. The migration-source volumes and migration target volumes or pools are in different THP/Smart pools.
3. The following conditions must be satisfied:
• The status is not blocked.
• The THP/Smart pool has more unused capacity than the migration-source volumes.
• Used THP/Smart pool capacity does not exceed both used thresholds 1 and 2 (even after a migration
is performed).
• THP/Smart pool subscription does not exceed the subscription warning and subscription limit (even
after a migration is performed).
• When selecting migration-target resources, if the option to create new THP/Smart volumes is selected,
the number of virtual volumes in the THP/Smart pool is less than the limit (HP P9500: 63,232;
XP24000/XP20000: 8,192).
4. The CLPRs for the migration target and migration source are the same.
5. If an external storage system is locked (not Read/Write), it cannot be a migration source or migration
target.
6. Volumes with virtual IDs specified cannot be selected as migration target volumes when:
• The migration target is a THP/Smart pool, and Create new THP volumes is selected in the migration
target creation options.
• The specified capacity differs from the capacity of the migration source.
