Conditions to migrate volumes in Legacy mode

Before migrating data, perform or confirm the following:

•

An HP StorageWorks P9000 Tiered Storage Manager software license is registered.

•

Create a tier.

•

Determine which data to migrate and which storage systems they belong to.

•

The emulation type, number of blocks, and size are the same for the source and target migration
volumes. However, note the following exceptions:

1.

If the micro version of XP24000/XP20000 is 60-03-20-00/00-xx or later and if both the
migration source and the migration target volumes are THP volumes, the emulation type can
be between OPEN-V and OPEN-0V.

2.

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 from the largest are displayed as
migration target volumes.

•

The LDKC:CU:LDEV number for the volume is in the range from 00:00:00 to 00:FF:FF

•

You can access the volumes and they are not reserved by other programs or tasks.

•

The emulation type is other than OPEN-V and both the migration source and the migration target
volumes are normal or both are CVS volumes.

•

Neither the migration source volume nor the migration target volume is an On-Demand device.

•

Volumes are not intermediate volumes.

•

Nothing is displayed in the Migration Restrictions section of the volume detailed information area.
However, if (target) is displayed at the end of the character string, the volume can be a migration
source volume.

LUSE volume conditions

If the source volume is LUSE volume:

•

A migration target must be selected for each volume that constitutes the LUSE.

•

Target volumes must be either all internal or all external volumes.

•

The LUSE volume can be migrated only if the target volume is not a THP volume.

•

The emulation type, drive type, I/O suppression mode, cache mode, and CLPR of all migration
target volumes must be the same.
