Fujitsu ETERNUS DX100 S3 - Figure 30 RAID Migration

•
Changing the encryption attributes
The encryption attribute of the volume is changed according to the encryption setting of the vol-
ume or the encryption attribute of the migration destination pool (TPP and FTRP).
•
Changing the number of concatenations and the Wide Stripe Size (for WSV)
•
Enabling the Deduplication/Compression function for existing volumes
The following processes can also be specified.
•
Capacity expansion
When migration between RAID groups is performed, capacity expansion can also be performed
at the same time. However, the capacity cannot be expanded for TPVs or FTVs.
•
TPV/FTV Capacity Optimization
When the migration destination is a pool (TPP or FTRP), TPV/FTV capacity optimization after the
migration can be set.
For details on the features of TPV/FTV capacity optimization, refer to "TPV/FTV Capacity Optimi-
zation" (page
47).

The volume type depends on
the migration destination.
A volume becomes encrypted
when moved to an encrypted
pool.

Specify unused areas in the migration destination (RAID group or pool) with a capacity larger than
the migration source volume. Note that RAID groups that are registered as REC Disk Buffers cannot
be specified as a migration destination.
RAID migration may not be available when other functions are being used in the
ETERNUS DX or
the target volume.
Refer to "Combinations of Functions That Are Available for Simultaneous Executions" (page 203)
for details on the functions that can be executed simultaneously, the number of the process that
can be processed simultaneously, and the capacity that can be processed concurrently.
During RAID Migration, the access performance for the RAID groups that are specified as the
RAID Migration source and RAID Migration destination may be reduced.
