■The maximum number of volumes / The maximum capacity of Thin Provisioning

Volumes for each model

RAID Migration creates a new volume. The following table shows the maximum number of vol-
umes and the maximum capacity of Thin Provisioning Volumes which can be created for each
model.
For the maximum number of volumes for each RAID Group, refer to "The maximum number of
volumes for each RAID Group" (page 168).
*1: The maximum number of volumes when creating Thin Provisioning Volumes. However, the actual
number of volumes that can be created is le s s th a n th e m ax i m u m va l u e a s s p e ci fi e d by t h e T h i n
Provisioning function.

•In addition to "Migration Source Volume Requirements" (page 214),
"Migration Destination RAID Group Requirements" (page 215), and
"Migration Destination Thin Provisioning Pool (TPP) Requirements"
(page 215), the following requirements must be met to execute
migration.
Click the [OK] button to return to the [Menu] screen if a message
appears, depending on the status of the ETERNUS DX400/DX8000
series.
-The total number of active migrations and TPV Balancing must be 31
or less
-The free space available for RAID Migration must be larger than the
total capacity of all the volumes available for RAID Migration
-The maximum number of volumes are not created in ETERNUS
DX400/DX8000 series.
-When Resource Domains are registered in ETERNUS DX400/
DX8000 series, work volumes can be assigned to the Resource
Domain to which the migration source volume belongs (*1)
*1: When Resource Domains are registered, and if the sufficient number of
Assignable Resources for Logical Volumes does not exist in the Resource
Domain to which the migration source volume belongs, migration cannot
be executed. The number of Logical Volumes that have been assigned to
the relevant Resource Domain and the number of Assignable Resources
can be checked using the [Resource Domain List] function.
•When the volume capacity of the new location is expanded with RAID
Migration, it is necessary for the server to recognize the expanded
volume capacity after the migration is complete. Refer to each OS or the
file system manual for operation from the server.
