start migration
This command starts RAID migration, which moves the currently registered volume to another RAID group or
Thin Provisioning Pool (TPP). The capacity of a volume can also be expanded at the same time.
The "start flexible-tier-migration" command is used to perform RAID Migration in which the destination is a
Flexible Tier Pool (FTRP).

-volume-number
or
-volume-name
This parameter specifies the volume identifier to be moved. Only one volume can be specified
at the same time. For details, refer to
"1.2.9 Volume Syntax" (page 22) .
-rg-number
or
-rg-name
-pool-number
or
-pool-name
This parameter specifies a RAID group or Thin provisioning pool as the volume migration
destination. Only one Thin provisioning pool can be specified at the same time. Use the "-rg-
number" or the "-rg-name" parameter to specify the RAID group as the migration destination.
Note that when multiple RAID groups are specified, the migration destination becomes a Wide
Stripe Volume. Use the "-pool-number" or the "-pool-name" parameter to specify the Thin
provisioning pool as the migration destination. For details, refer to
"1.2.8 RAID Group Syntax"
(page 22) or "1.2.5 Thin Provisioning Pool Syntax" (page 20) .
-size Optional. This parameter specifies the volume size of the migration destination. A different
volume size from the source size can only be specified for the destination when performing
migration between RAID groups with a volume size that is larger than the source size. If the
volume size that is specified for the destination is smaller than the source size, a parameter
error occurs. If omitted, the same size as the source volume is set. Select whether terabytes
(TB), gigabytes (GB), or megabytes (MB) are used for the capacity. The size cannot be changed
when the migration destination is a Thin provisioning pool.
Example: 1tb, 120gb, 200mb
