*1 : This indicates that the copy session is being set or the copy session is already set.
*2 : This indicates the copy session setting operation.
*3 : Using the "Format Volume" function will cause losing the entire data in volumes.
*4 : The function cannot be executed when the same volume is set as the execution target.
*5 : LUN concatenated volumes can be set as the RAID Migration source.
Note that LUN concatenated volumes cannot be set as the RAID Migration destination.
*6 : RAID Migration that expands the capacity cannot be performed on any volumes with copy sessions in LUN
units.
*7 : The function cannot be executed when the same RAID group is set as the execution target.
*8 : When a copy session with a copy area that is specified in LUN units exists, volume capacity expansion
cannot be performed because copying cannot be processed for the expanded part. When a copy session is
specified for a logical disk, volume capacity expansion can be performed.
*9 : Copy sessions in LUN units cannot be performed on a volume that is being expanded with RAID Migration.
*10: Complies with Advanced Copy specifications (multi-copy/Cascade Copy).
*11: The motor-off state of Eco-mode is stopped, and the drive motor is activated (spin-up).
*12: EC can be performed (the motor-off state of Eco-mode will be stopped).
OPC/QuickOPC/SnapOPC/SnapOPC+ cannot be performed (the ETERNUS DX returns an error).

Number of Processes That Can Be Executed Simultaneously

The following upper limits are applied to the number of processes that are to be executed.
• Only one process can be executed with Logical Device Expansion (LDE). Two or more processes cannot be exe-
cuted simultaneously in the same device.
The total number of TPV balancing and RAID Migration processes that can be performed at the same time is
•
32.
Capacity That Can Be Processed Simultaneously
The following upper limit is applied to the capacity of processes that are to be executed.
The total capacity of TPV balancing and RAID Migration processes that can be performed at the same time is
•
128TB.
